Many protocols that have been proposed are not really convenient for mobile ad hoc networks. We propose a group activity key agreement protocol (GAKAP) that aims to solve problems, such as mobility, unreliable links, and multihop communication cost, that are specific to ad hoc networks. The main idea is to focus on group dynamics and complete node mobility in the ad hoc environment to develop an adaptive protocol that is suitable for the network and group changes. Doing so, we extend and adapt the proposed tree based group Diffie-Hellman (TGDH) protocol to the pure mobile ad hoc network. We simulated our protocol over the Opnet environment under various mobility, group size, and group dynamic scenarios.","PeriodicalId":366183,"journal":{"name":"29th Annual IEEE International Conference on Local Computer Networks","volume":"171 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116399854","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 multi-fractal nature of traffic volume in general is well known to have a significant influence on queueing behavior in short time scales. In our previous study, we showed that the retransmission time out (RTO) mechanism plays an important role in the multi-fractal nature of TCP traffic. In this paper, we investigate how to control the multifractal nature of TCP traffic in a real network. Here we focus on the random early detection (RED) mechanism in order to reduce the occurrence of RTO. We evaluate the RED mechanism from the viewpoint of its multi-fractal nature and show that the RED mechanism improves not only throughput and delay performance, but also the multi-fractal nature of TCP traffic.","PeriodicalId":366183,"journal":{"name":"29th Annual IEEE International Conference on Local Computer Networks","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114480568","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}

They use either the packet gap model or the packet rate model whereby probe packets are sent and analyzed at the destination to infer the available bandwidth in the tight link. Available bandwidth estimations can be very useful in many different scenarios and applications. We use available bandwidth estimation techniques (ABET) for flow and congestion control in TCP. We first evaluate the performance of Pathload, IGI and pathChirp in terms of their accuracy, intrusiveness, and overhead. Using simulations, we perform a 2/sup k/ factorial design to analyze the importance of the packet size, number of trains, number of packets per train and frequency of run in these performance metrics. Then we utilize these results to embed the most appropriate tool with the best set of parameters in a modified version of TCP SACK to solve the \"blindness\" of TCP when changing its congestion window and threshold values. Our simulations show that, using the available bandwidth estimates provided by IGI instead of the \"by half\" reduction rule of TCP, the throughput of the proposed ABET-based TCP version is improved compared to the plain TCP SACK.","PeriodicalId":366183,"journal":{"name":"29th Annual IEEE International Conference on Local Computer Networks","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126187378","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}

In our approach, sensor network packets, rather than being stopped at the gateway, are instead encapsulated into IP packets, and then directed from the gateway to any number of interested applications and services residing remotely on the Internet.","PeriodicalId":366183,"journal":{"name":"29th Annual IEEE International Conference on Local Computer Networks","volume":"27 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123077374","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}

However, the energy constrained and limited computing resources of the sensor nodes present major challenges in gathering data. In this work, we propose a new distributed clustering and data aggregation algorithm, CODA (cluster-based self-organizing data aggregation), based on the distance from the sink in ad-hoc wireless sensor networks. While cluster-based data gathering is efficient in energy and bandwidth, it is difficult to cluster efficiently. We use the distance vector from the sink, which affects the energy depletion of the network. Our simulation results show that the proposed algorithm balances the energy dissipation over the whole network thus prolongs the network lifetime.","PeriodicalId":366183,"journal":{"name":"29th Annual IEEE International Conference on Local Computer Networks","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133076746","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}
