Simulation of the ALOHA protocol

Simulation of the ciao protocolAbstract-The present essay is a tutorial on the OMNeT++ pretense environment, through the analysis of the cognise ciao protocol. The model implements the ciao random price of admission protocol on the Link layer, and simulates a host to server instant hand out. aloha is rather plain soon enough convenient to demonstrate the potential of OMNeT++ in simulating radiocommunication protocols. The final part evaluates the pure and the slotted ALOHA variations, in regard to the theoretical models.IntroductionOMNeT++ is a distinct typeface pretence (DES) environment, developed by Andras Varga as public source, and is accompanied by Academic Public License, which means that it is free for nonprofit academic use. The target behind OMNeT++ was the development of an open source generic poser environment, not exclusively dedicated to network simulations as the more than known ns-2, or the commercialized Opnet. The environment offers instead, a generic and flexible platform to develop simulation positionworks dedicated to complex IT systems, as wireless and sensor networks, the patternic IP and IPv6 stacks, queuing networks, ocular networks and various hardw atomic number 18 architectures.Typical example of a framework that provides simulation components for IP, TCP, UDP, Ethernet and MPLS, is the INET Framework and the MiXiM, which is an aggregation of several frameworks for mobile and wireless simulations. The OMNeT++ ver. 4.0 is built on the known Eclipse CDT ver. 5.0, and uses most of its resources. It is offered for Windows and Linux operating systems. The core of the models is coded in C++, in Linux uses the gcc compiler and in Windows uses the MinGW port for the gcc suite. There is a commercial version called OMNEST, with no signifi can buoyt accessories than the open version, except the optional use of the native Visual C++ compiler for the Windows platform.The ALOHA protocol was one of the oldest random access protocol s, invented by Norm Abramson in 1969. The first wireless network, implementing packet switching over radio, used the pure ALOHA variation, have initially established in Hawaii. later(prenominal) Abramson interfaced the ALOHAnet with the ARPAnet, the primitive form of internet. The ALOHA have inspired the creation of CSMA/CD and the birth of Ethernet. Finally, the random access protocol has evolved to contemporary CSMA/CA, the MAC layer of Wi-Fi. The slotted ALOHA and the later pure ALOHA have unproblematic implementations, portion for simulation. It uses only the host to server broadcast instant, but is adequate to calculate the supreme pass on capacity and demonstrate some opposite interesting attributes, as well.OMNeT++ DESCRIPTIONThe Structure of ModelsOMNeT++ is based on C++ programming and fol low-downs the object-oriented approach with classes and class instances, the so-called objects. The simulation model consists of modules, which communicate by message passing. The core element is the simple module, which is written in C++, and constitutes an instance of a module slip from the simulation class library. The adjacent structural element in the hierarchy is the entangled model, which is formed from simple modules or other compound models. E very module, simple or compound, has ports to communicate with the external environment, called furnish. Gates could be bidirectional or could be restricted to input or output. Modules are connected through their gates via connections and they communicate by exchanging messages, via these connections.The block diagram in Fig. 1 depicts the internal module structure gibe to the declare hierarchy, in OMNeT++. The connections are limited indoors the module range but the message exchange can be established across hierarchy levels. This is applicable in the case of modeling wireless systems and the simulation of ALOHA institutionalizes will make use of it. Otherwise, messages are traveling through the chain of connections. Modules have parameters, which are used to pass initialisation data during the initiation of the simulation. The compound models can pass parameters to the contained sub-modules. The final model which contains the aggregate of the modules is called network model, is represented as a class and each simulation run is executed on an instance of this class.The NED languageThe structure of the simulation in OMNeT++ is based on the network interpretation language (NED). The NED includes declarations for the simple modules and definitions for the compound modules and the network model. The language programming is accomplished by the integrated graphic editor, as shown in Fig. 2 or the text editor, as shown in Fig. 3. both(prenominal) editors are producing equivalent code, and the coder can switch from one another without any derogation.The programming modelThe typical code development includes the hobby stairs The programmer creates the network model, by creating the ap propriate network_name.ned cross-file, using the IDE. The NED file describes the network name and the topology, which are the names of the sub-modules, simples and compounds. Every sub-module should have its own module_name.ned file, which includes the parameter declarations and other meta-data. As mentioned, the demeanour of every(prenominal) simple module is expressed in C++, so there should be two specific files, the module_name.cc and the module_name.h, for every simple module. These files are compiled during simulation execution by the supporting C++ compiler, and linked with the simulation kernel and libraries.The programmer usually tests the behavior of the simulation model according to different inputs. These could be entered manually by the user, during simulation execution, or could be included in a configuration file. Generally, there is a special caseful of file the omnetpp.ini that contains these parameters and the rest of the building blocks, to support user intera ction. The IDE includes an editor for the initialization files, which can switch between form view, as shown in Fig. 4, and source view, as shown in Fig. 5. The two fields are equivalent.There are two fundamental methods to develop C++ code for programming the simple module behavior The co-routine based and the event processing function. In the first approach, every module executes its own threat of code, which is activated every judgment of conviction it receives a message from the simulation kernel. In the last approach, the simulation kernel calls the module function, having the specific message as argument. Prior to main() function execution, an initialization function declares variables and objects and before program termination, a finalization function saves the data logged during simulation, and produces histograms.OMNeT++ Architecture and PotentialityThe next Fig. 6 presents the internal logic structure of OMNeT++. The first block is the model component library, which the programmer develops in C++, and contains the compiled code of simple and compound modules. The simulation kernel and the class library (SIM) instantiates the modules and build the concrete simulation model. The user interface libraries (Envir and Cmdenv or Tkenv) provide the simulation environment, which defines the source of input data, the sink of simulation results and the debugging information. It controls the simulation execution, visualization and animation.Cmdenv provides only command line and text mode input-output, and it is more appropriate for batch simulations. Tkenv is the graphical user interface (GUI) of OMNeT++. It provides automatic animation, module output windows and object inspectors. The following Fig. 7 depicts an active simulation output through OMNeT++/Tkenv.OMNeT++ includes very powerful tools to visualize the interaction among modules. A sequence chart diagram provides a way to inspect the timing of the events during simulation by extracting data from an ev ent log file. During the finalization routine, the logged data are saved to specific result files, the vectors in network_name.vec and the scalars in network_name.sca files, respectively. For the result analysis, OMNeT++ produces the analysis file network_name.anf, which contains aggregated data in vectors and scalars plus any histograms, created during the final stage. All the types of data can be further processed by using pattern rules, in datasets and charts section, to produced advanced charts and graphs. In the ALOHA simulation most of the available choices are used for demonstration. aloha SimulationBackground TheoryThe slotted ALOHA is the most simple random access protocol. The transfer station always broadcasts at the full rate R of the channel. The transmission initiates at the first-class honours degree of the slot, which is common for the aggregate of the displace. If two or more stations transmit simultaneously, then the condition is called collision and all the sta tions involved, after a random metre different for each, retransmit the frame until thriving delivery. The procedure is presented at the following figureThe slotted ALOHA protocol allows each station to transmitat at the channels full speed R, but requires slots to be synchronized in all the stations, something not nessesary for the unslotted or pure ALOHA. The following assumtions are made to simplify simulationThe source generates single frames of length L bits. The inter-arrival times between frames follow exponential distribution. If R bps is the capacity of the wireless link then the slot time is set equal to the transmission time of each frame, which is tframe=LR sec.All nodes are synchronized and transmit frames only at the beginning of a slot.If a node has a new frame to send, it waits until the beginning of the next slot.If two or more frames collide, then their hosts retransmit after random time, following exponential distribution.If there is no collision, then the nod e transmits its next frame following exponential distribution.I define N the number of stations operating the slotted ALOHA protocol and p the probability of each station to transmit in the next slot. The probability for the same station to do not transmit in the next slot is then 1-p, and for the rest of the stations is 1-pN-1. Therefore, the probability for a station to have a successful transmission during the next slot is to transmit and the rest of the stations to do not transmit, so it is p1-pN-1, and because there are N stations, the probability that an arbitrary node has a successful transmission is Np1-pN-1.A slot where a single station transmits is called a successful slot. The efficiency of slotted ALOHA is defined as the long run fraction of successful slots, which isEp=Np1-pN-1 (1)To find the supreme efficiency, we seek p* that maximizes (1). ThenEp=N1-pN-1-NpN-11-pN-2=N1-pN-21-p-pN-1If Ep=0 then p*=1N . Using this value, the maximum efficiency isEp*=N1N1-1NN-1=1-1NN-1 =1-1NN1-1N (2)For a large number of active stations, the maximum efficiency accrues from (2) as N approaches infinitylimNEp*=limN1-1NNlimN1-1N=1e1=1e=0.368 (3)From (3), the maximum efficiency of slotted ALOHA is 0.368 or 36.8%The unslotted version or pure ALOHA protocol does not have the restriction of slot synchronizing, and the station is able to broadcast when a new frame is available. So pure ALOHA is a full-decentralized random access protocol. When a transmitting station detects a collision, after complete the transmission, it retransmits the frame with probability p. If it chooses to postpone the transmission for a single frame transmission period tframe=LR sec, then the probability is (1-p). The figure below depicts transmissions and collisions in the unslotted channel.The maximum efficiency of pure ALOHA protocol is calculated similarly as the slotted ALOHA. The only difference here is that the rest of the stations should have not begun transmitting before and should not b egin during the broadcast of the assumption station. The probability that the rest of the stations remain idle is 1-pN-1 and the probability that they remain idle is 1-pN-1 again. Therefore, the probability that the given station will have a successful transmission is p1-p2N-1.Again, we seek the value of p* that maximizes (4), which is the probability of successful transmission for the sum of the N stations.Ep=Np1-p2N-1 (4)Ep=N1-p2N-2-Np2N-11-p2N-3=N1-p2N-31-p-p2N-1If Ep=0 then p*=12N-1 . Using this value the maximum efficiency isEp*=N2N-11-12N-12N-1 (5)From (5), the maximum efficiency accrues as N approaches infinity, which islimNEp*=121e=12e (6)From (6) I assume that the maximum efficiency, for the pure ALOHA protocol, is 0.184 or 18.39%, the half of slotted ALOHA.Another useful diagram is in Fig. 10. It depicts the apparent superiority of slotted ALOHA over the pure ALOHA protocol, despite the limitations that turn it to non-functional. The normalized intact concern is the agg regate traffic, which generated by the source of the station, divided by the channel capacity R and the normalized throughput ? is the average successful traffic (non-collided) divided by R. The slotted ALOHA achieves double throughput than the pure ALOHA and achieves its maximum efficiency when the generated traffic rate equals the channels capacity R. The pure ALOHA although, achieves its maximum efficiency when the generated traffic equals to R/2.Model DevelopmentNED languageThe following paragraphs describe the process of creating a functional model for the simulation of ALOHA protocol in OMNeT++. The object of simulation is to study the behavior of the ALOHA model and to confirm the theoretical values of maximum efficiency for pure and slotted ALOHA. The ALOHA random access protocol is associate based and does not use a server-client architecture. It is convenient to study the effect of collisions and random retransmissions only in the case when one host is receiving (becomes server) and the rest of the hosts are transmitting.The first step is to develop the NED code that describes the network Aloha. The following Aloha.ned file creates the Aloha network, which consist of simple modules, one called server and a number of hosts, equal to num legionss parameter. The txRate defines the transmission rate R, of the wireless channel, and slotTime defines the type of protocol. Zero means pure ALOHA and 100ms defines the slot time length. The parameter display selects a background image, interpreted from the library.network Aloha parameters int numHosts // number of hosts double txRate unit(bps) // transmission rate double slotTime unit(ms)// zero means no slots (pure Aloha) display(bgi=background/terrain) submodules server server hostnumHosts Host txRate = txRate slotTime = slotTime The following Server.ned file describes the servers simple module. It debauchs an image for the server icon and defines a gate of input type (in), with which it is not necessary t o establish a connection. It can receive a message directly from a host via directIn, something that is usual to wireless simulations.simple Server parameters display(i=device/antennatower_l) gates input in directInThe following Host.ned describes the hosts simple module. It loads a set of parameters from the omnetpp.ini file, the radioDelay, which is the propagation delay over the radio link, pkLenBits, which is the length of the frame, and iaTime, which is the random inter-arrival time, following exponential distribution. The rest of the parameters, txRate and slotTime, are sozzled in Aloha.ned, during sub-module instantiation.simple Host parameters double txRate unit(bps) // transmission rate double radioDelay unit(s)// propagation delay of radio link volatile int pkLenBits unit(b) // packet length in bits volatile double iaTime unit(s) // packet interarrival time double slotTime unit(s) // zero means no slots (pure Aloha) display(i=device/pc_s)ConfigurationThe most critical fil e is the configuration file omnetpp.ini. It stores the values of the parameters that are loaded in the NED parameter fields. When declaring on the General field that Aloha.slotTime=0, is presets globally the pure ALOHA protocol. Similarly, the Aloha.numHosts=20 defines the number of hosts to be 20, the Aloha.txRate=9.6kbps defines the R to be 9600bps. The last definitions load the parameters of Aloha model and consequently the parameters of the simple modules that Aloha model controls, which are the server and the host modules. The definitions Aloha.host*.pkLenBits=952b and Aloha.host*.radioDelay=10ms load directly the parameters pk.LenBits and radioDelay on every host submodule, respectively.Generalnetwork = Alohadebug-on-errors = truerecord-eventlog = trueAloha.numHosts = 20Aloha.slotTime = 0 no slotsAloha.txRate = 9.6KbpsAloha.host*.pkLenBits = 952b =119 bytes, so that (with +1 byte guard) slotTime is a nice round numberAloha.host*.radioDelay = 10msConfig PureAloha1description = pure Aloha, overloaded too frequent transmissions result in high collision rate and low channel utilizationAloha.host*.iaTime = exponential(2s)Config PureAloha2description = pure Aloha, best load near optimal load, channel utilization is near theoretical maximum 1/2eAloha.host*.iaTime = exponential(6s)Config PureAloha3description = pure Aloha, low traffic very low traffic results in channel being idle most of the timeAloha.host*.iaTime = exponential(30s)Config PureAlohaExperimentdescription = Experimental mutliparameter demostrationrepeat = 2sim-time-limit = 90min**.vector-recording = falseAloha.numHosts = $numHosts=10,15,20Aloha.host*.iaTime = exponential($mean=1,2,3,4,5..9 step 2s)Config SlottedAloha1description = slotted Aloha, overloaded slotTime = pkLen/txRate = 960/9600 = 0.1sAloha.slotTime = 100ms too frequent transmissions result in high collision rate and low channel utilizationAloha.host*.iaTime = exponential(0.5s)Config SlottedAloha2description = slotted Aloha, optimal load slotTime = pkLen/txRate = 960/9600 = 0.1sAloha.slotTime = 100ms near optimal load, channel utilization is near theoretical maximum 1/eAloha.host*.iaTime = exponential(2s)Config SlottedAloha3description = slotted Aloha, low traffic slotTime = pkLen/txRate = 960/9600 = 0.1sAloha.slotTime = 100ms very low traffic results in channel being idle most of the timeAloha.host*.iaTime = exponential(20s)A selection of the SlottedAloha2 configuration overrides the value of slotTime with Aloha.host*.slotTime=100ms, which fixes the slotted ALOHA protocol with slot time to 100ms. The Aloha.host*.iaTime=exponential(2s) sets the frame inter-arrival time on every host to follow exponential distribution, with mean time equals to 2 seconds.The Config option PureAlohaExperiment exploits the OMNeTs capabilities of organizing different experiments with simple repetition declarations. The statement Aloha.numHosts=$numHosts=10,15,20 declares common chord (3) repetitions having 10, 1 and 20 hosts respec tively.The statement Aloha.host*.iaTime=exponential($mean=1,2,3,4,5..9 step 2s) declares seven (7) repetitions, with interarrival times equal to exponential distribution and means, 1, 2 ,3, 4, 5, 7 and 9, respectively. The repeat=2 statement doubles the number of runs, so finally the available choices will be 2x3x7=42 from 0 to 41 optional runs. The statement sim-time-limit=90min constrains the simulation time to 90 minutes.C++ model codingThe simple modules Host and Server are based on C++ programming. The relevant host.cc, host.h, server.cc and server.h, which are included merely in the appendix section, implement the model behavior during simulation by exchanging messages directly one-another or with the simulation kernel. The following Fig. 11 is a design- level class diagram, describing the basic relationships among network module Aloha and simple modules, Host and Server. The two last, inherit from cSimpleModule simulation class library, and redefine the basic methods initial ize(), handleMessage(), activity() and finish(), according to the desired function.The Aloha network model comprises of several Host objects and one Server, so it keeps an aggregation association with Host and Server classes. It passes also to them some parameter values, some declared in the omnetpp.ini file and some taken from user dialog form. The Host module keeps an one-way association with Server because every Host declares a Server object in the attribute field, in order to send a direct message (pk) later, by calling the sendDirect() function. The scheduleAt() function programs the kernel to send the Host an endTxEvent message when the transmission ends. This is represented by the self-association. Similarly, the Server module programs the kernel to send the Server an endRxEvent, when the reception of the message sent from Host finishes, and is represented as the self-association.The module code is cited commented in the appendix. Here, I will explain the finish() function of the server module, because it creates the result reports, necessary for the exploitation of the simulation.void Serverfinish() EV

Religion and Politics Essay examples -- Papers Church State Separation

Religion and Politics Both liberals and conservativists put one over become quite adept at mixing religion and politics in our current society. One also continues to observe an ongoing practice of civil religion demonstrated by presidents and office-seekers on twain the left and right. Generally, the leftist merger of religion and politics has received greater social acceptability because it has been cloaked in such rights causes as civil rights, womens rights, or economic rights (the social distri moreoverion of wealth). The advocating of these rights issues have provided an appearance of transcending religion, keeping the left relatively free from criticism of any church and state overlap. delivery boyian Conservatives, however, have found it more difficult to reasonably combine tru stingness and politics because they have more overtly recognized that their political positions are grounded on faith assumptions. This has resulted in numerous attacks by both non-Christians and Christians alike against the conservative attempt to merge religion and politics. Three arguments have been used most frequently against the conservative mixture of religion and politics. In what follows each of these arguments is stated and then refuted. The first argument is that politics is too worldly. The essence of the argument is that politics is part of this worlds system, and Christ clearly taught His followers to love not the world, and to flee from worldly activities. There is a danger of becoming caught up in th... ...hermore, in the Bible in that location is much political activity by Gods servants. The judges and kings ruled under God. The prophets and Moses were quite political. Daniel served in the civil governments of Babylon and Persia. Joseph g overned in Egypt. The Apostles spoke of following Gods rules rather than mens. In conclusion, to be obedient to Christ requires political activity. Jesus is quite clear about the need to overcome social injustices. If Christ tells us to confront the forces of evil, but society tells us not to, and even makes a law against bringing religion into politics, then who should we follow, the state or Christ? In the broadest sense, we are called to political activity because we are responsible to apply Christian principles and standards to all areas of our society, and politics is one of these areas.

Sonnys Blues (An Insight) Essay -- essays research papers

Baldwins Sonnys Blues, set in Harlem in 1957, was largely about the struggles of an ethnic minority and the stagnancy they feel, scarcely moreso how two brothers come to understand each other due to their struggles and from years of living their own, very different lives. Baldwins constant, detailed, reflections helped me immensely in understanding this story. I feel that they served as a constant reminder of the social context in which this story takes take aim. It helped to have those incessant reminders because I kept thinking it takes place in recent years, versus the 1950s, before the Civil Rights Movement was in full swing. The biggest idea that I had to keep open in mind was that the racism (ultimately leading to stagnation/oppression) presented in the context was accepted at this point in time. By accepted I mean that there were not yet any indite laws in place to protect blacks against these acts, not that the actions were morally correct or acceptable. Sonnys side of t he story represented one perspective of the African American experience in this time period. He accepts his status & tries to live within the black culture and deal with it distress that goes along with it, just to keep his dignity. At first, he channels his afflictions through music. There eventually becomes a time in his life when can no longer deal with the torture or suffering and Sonny takes the well-beaten path of turning to heroin, t...

Manhood and Heroism in Joseph Conrads Heart of Darkness :: Heart Darkness essays

Heart of Darkness Essay Manhood and Heroism Civility, civilization and civilize, are they and could they be mans defense against the power and mystery of nature and the primal nature of himself? When man lives away from refinement and education and is living in the natural habitat of ocean, jungle, and forest, there can be seen a disaster of a warrior, in the destruction of nature and himself. In The Heart of Darkness, Joseph Conrad must go on a quest to discover the fire and warmness in his male being and ignite the flame in his heart that is the fuel for his will to survive in the earth. The immediate relationship to the Thames River and his merging brain with that element, reflect back to him a memory of myth and history of all the archetypes of man and warriors who also as he, was engaged and moving in this famous passage. The sea has parted and has opened all past memory to the strong images that have crystallized before him of his first journey where man and sea began. The sea is a mans world where he goes through trials and initiations that test his manhood, and why? Is there an obsession in our past history and today with manliness and workforce? If aliens were to study our cultures, they definitely would notice something very strange. It is our favorable obsession with manhood that is considered a test to be passed, which creates unnecessary arenas of war, and work that links man with the social stresses of protecting, providing and procreating. In The Heart of Darkness there is the fear of a man not being man enough. The tragedies of a hero and the hazards of heroism are that the more he fights the enemy, the more he begins to be like the enemy the more he kills beasts, the more he becomes like a beast.

Industrialization - Economic Change and Effect :: European Europe History

Industrialization - Economic Change and EffectSince the 19th century, industrialization has had positive and negative makes on the live of workers. Industrialization is the answer of modernization and mass production of most goods. This also includes but not limited to mining and the forging of iron. An area where industrialization had a massive effect was in Eastern Europe. It emerged as a need to modernize and unify Europe. Although Britain led industrialization at first, it quickly exploded from Spain all the way done Russia. Early in the industrial revolution Britain stood alone as the worlds industrial giant. To protect its head start Britain smudged strict laws monitoring the exportation of inventions. accordingly in 1807 a British mechanic William Cockerill, opened factories in Belgium for the manufacturing of spinning and weaving machines. Belgium thus became the first European nation to industrialize. By the mid 1800s, opposite nations had joined the race, and several newcomers were challenging Britains industrial supremacy. The effects of industrialization were especially obvious in Germany. By the late 1800s Germany had setup a standard for chemic and electric companies worldwide. Germany was second only to Britain among the European powers. Germany spectacular growth was due to the ample amount of iron and coal resources in the area. A disciplined and ameliorate work force also helped the economy, while a rapid growing population provided a huge home market and a highly consummate work force. It almost eliminated the poverty factor in Germany due to the vast availability of employment. But along with the attributions of industrialization also came the bad. Poor work place conditions lead to work place abuses. Workers were forced to work long hours for little pay and even children were abuses during this time. Some of the abuses were children as young as 7 could be seen in work places, sexual discrimination was present. Women were often hire d in factories because they could be paid less then men. And pollution was also a sound problem. These were among the most common problems of the time and these were too often seen in most if not all the work places. Workers were outraged by these abuses and how the government, at the time, did nothing to help. Workers ceremonious unions and won the right to bargain with employers for better wages and hours. And eventually the government passed laws regulating the employment of children and set safety regulations in the work place.
