In order to achieve good performance, the formation and maintenance procedure of clusters should operate with minimum overhead, allowing mobile nodes to join and leave without perturbing the membership of the cluster and preserving current cluster structure as much as possible. In this paper, we propose a Flexible Weight Based Clustering Algorithm (FWCA) in Mobile Ad hoc Networks. The goals are yielding low number of clusters, maintaining stable clusters, minimizing the number of invocations for the algorithm and maximizing lifetime of mobile nodes in the system. Through simulations we have compared the performance of our algorithm with that of WCA in terms of the number of clusters formed, number of re-affiliations, number of states transitions on each clusterhead and number of clusterheads changes. The results demonstrate the superior performance of the proposed algorithm.","PeriodicalId":217322,"journal":{"name":"2006 International Conference on Systems and Networks Communications (ICSNC'06)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122739051","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}

The scheme associates each mobile agent with a set of roles, each of them belong to a communication layer. This allows the decoupling between the roles and physical locations or responsibilities of the mobile agents. Thus, the messages are typed by the layer that supports them. By separating the concerns of locating the mobile agent and delivering the message to the agent, we create a flexible protocol of data exchange.","PeriodicalId":217322,"journal":{"name":"2006 International Conference on Systems and Networks Communications (ICSNC'06)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117194299","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}

One of the issues scarcely addressed in PBNM is the stability of the managed system as the result of the dynamic interaction between the ¿natural¿ network behaviour and the autonomous management decision making. Yet this issue is central to the design of a self-management networking system comprised of autonomous entities making decisions driven by policies with often unknown consequences. Decisions made by one entity may change the context and configuration of other autonomous entities which may in turn react changing the context and configuration of the first entity triggering an unbounded chain of re-configuration actions. It is possible to model obligation policies and their constraints with finite state transducers (FST). It is also possible to learn patterns of recurrent behaviour using Bayesian networks (BN), a structurally similar kind of graph. The method presented in this paper analytically composes both finite state machines to derive predictions of the consequences of enforcing a given policy improving system stability.","PeriodicalId":217322,"journal":{"name":"2006 International Conference on Systems and Networks Communications (ICSNC'06)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127955311","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}

While previous studies of allocation methods considered a single wireless link communication, the goal of this study is to examine the use of multiple wireless links and to get them access the Internet from wireless terminals. By employing multiple wireless links, TCP performance is improved significantly. But the improvement depends on the wireless environment. Although Internet applications apply some network protocols such as TCP, UDP, etc., the allocation method should take into account some other protocols. The proposed system allocates several wireless links to wireless terminal. This allocation is based on the estimated TCP throughput and current traffic of each base station. The current traffic of each base station, which includes many network protocol¿s flows, is considered by the system. Our allocation method not only considers the effect of TCP, but it also considers the effect on other protocols. In addition, wireless links are preferentially assigned to the wireless terminal that has the largest performance improvement per wireless link. Therefore, the improvement in the whole system performance compared with the previous technique can be easily achieved. This achievement is fulfilled in spite of the allocation with a fixed threshold value in the conventional scheme.","PeriodicalId":217322,"journal":{"name":"2006 International Conference on Systems and Networks Communications (ICSNC'06)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131235608","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}

The scheme is based on monitoring the elapsed real time of handoff calls and according to a time threshold parameter, handoff calls are either prioritized or treated as new calls. The scheme is modeled using a onedimensional markov chain and numerical analysis is presented to estimate blocking probabilities of new calls, dropping probabilities of handoff calls and system utilization. The scheme is simulated under different network conditions. It is observed that analytical results closely match the simulation results. The results show that the proposed scheme yields a considerable enhancement in terms of performance/cost ratio when compared with the conventional schemes.","PeriodicalId":217322,"journal":{"name":"2006 International Conference on Systems and Networks Communications (ICSNC'06)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123446660","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}

Adjusting transmission power levels has an important impact on energy efficiency and network lifetime in wireless sensor networks. In this work, we proposed a localization scheme with power control in a wireless sensor network. Each node can transmit beacon packet in different power levels. Whenever a node receives beacon packets transferred in different power levels, it will adaptively select beacon packet to estimate distance to the landmark. When a sensor node has estimated the distances to three landmarks, it can compute its location by triangulation. Simulation results show that the proposed scheme can improve the error rate of localization.","PeriodicalId":217322,"journal":{"name":"2006 International Conference on Systems and Networks Communications (ICSNC'06)","volume":"148 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124348113","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}
