When multiple nodes contend for channel access simultaneously, the base station initiates a collision resolution epoch where a set of cooperating nodes retransmit either their own packets, if they were involved in the collision, or the signal that they heard during the collision slot, until the base station has enough linearly independent collided signals to recover the packets. The throughput and service delay of such protocols depends critically on the rate that independent signals may be generated, which in turn depends critically on the underlying channel diversity. We consider two natural models for \"imperfect\" retransmission schemes where insufficient diversity extends the duration of the retransmission epochs, thus lowering the effective throughput. The throughput optimal medium contention probabilities for both models are obtained as a function of the measure of imperfection. The analysis permits a meaningful and quantitative framework for assessing the strengths and weaknesses of cooperative retransmission MAC protocols.","PeriodicalId":311005,"journal":{"name":"International Workshop on Performance Monitoring, Measurement, and Evaluation of Heterogeneous Wireless and Wired Networks","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123540500","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Wireless medium access control (MAC) protocols use distributed contention resolution mechanisms for sharing the wireless medium. Wireless nodes decide access to their channel independently and accessing the channel by a node has an influence on those of other nodes. In this environment, selfish nodes that do not obey the operation of the MAC protocol may obtain an unfair share of the channel bandwidth at the expense of well-behaved nodes.\u0000 Game theory is a useful and powerful tool to research this kind of systems. We study the effect of misbehavior in CSMA/CA wireless LANs and in particular in Idle Sense access method which has been designed to optimize the performance and fairness of the network using game theory. We show that Nash equilibrium point of our game is not an optimal point of the game. Then we find the Pareto-optimal point of our game using static game model from Nash bargaining framework. We design a prevention model to force nodes converge to the Pareto-optimal point and make the Pareto-optimal point as the Nash equilibrium point of our game. Finally, we devise a detection system to detect deviating cheaters from optimal point.","PeriodicalId":311005,"journal":{"name":"International Workshop on Performance Monitoring, Measurement, and Evaluation of Heterogeneous Wireless and Wired Networks","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124534818","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Combined with the fact that such networks are often deployed for critical missions like forest fire detection in the WSN scenario or have to function properly and efficiently for an extended period of time, it is desirable to thoroughly test, analyze and evaluate newly developed communication protocols before deployment. In order to do this, simulations are a good compromise between cost/complexity and accuracy of the results. Since there are many simulators for wireless networks, it is often difficult to decide which one to choose. Therefore, we present a case study in which four common wireless network simulators were used to evaluate a well-known topology control protocol (SPAN). Within the case study, we describe the strengths and weaknesses of the examined network simulators: First, we evaluate the usability of the simulators in terms of different parts of the protocol developer's work process. Moreover, we also focus on the simulator's support for reusability and maintainability of simulation models by measuring particular model properties. For this purpose, we have proposed a model of quality for network simulators. The model of quality defines which properties of models to measure and how to interpret them. As opposed to other simulator comparisons, we do not focus on the correlation of the individual simulation results. Through this paper, we aim at providing a basis for finding an adequate simulator for a particular task.","PeriodicalId":311005,"journal":{"name":"International Workshop on Performance Monitoring, Measurement, and Evaluation of Heterogeneous Wireless and Wired Networks","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122566377","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
