The network traces record detailed information about wireless Internet packet data call activity on the network, including mobile station identity, call initiation, burst behaviour, supplementary channel usage, soft handoffs, and call termination. The analysis in this paper focuses on one continuous week-long trace data set, representative of cellular data network activity. The results from the analysis illustrate the burstiness of the packet call arrival process and the diurnal patterns of cellular data users. The results also characterize the activity per cell site, activity per user, data burst activity, user mobility, and the density of cellular network coverage. Several observations reinforce known results about heavytailed properties in wired Internet traffic, while others show interesting differences in wireless versus wireline traffic","PeriodicalId":368269,"journal":{"name":"The IEEE Conference on Local Computer Networks 30th Anniversary (LCN'05)l","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114741642","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}

A modified genetic algorithm is used to find the optimal configuration of location areas in a mobile network. The location areas configuration of the network is modeled so that the general condition of all the chromosomes of each population improves rapidly. Since a generic genetic algorithm will not be so efficient in solving this problem, several modifications have been made to the genetic optimizer to improve its performance. These modifications deal with the mutation operation where three types of mutation are considered after the crossover operation of the genetic algorithm.

However, scatternet formation is one of the challenges that need to be resolved since the performance of a Bluetooth network depends largely on the scatternet topology used. We first identify a particular variant of a height-balanced binary tree, termed ACB-tree for almost-complete-binary tree, that allows two such trees to be combined to create a larger ACB-tree while retaining the height-balance requirement. We then present a distributed scatternet formation algorithm for creation of ACB-trees. We further extend the algorithm to produce an ACB-tree scatternet with energy efficient properties. We also present simulations, conducted using Blueware simulator, to provide experiment results to study and compare the performance of the resulting scatternets","PeriodicalId":368269,"journal":{"name":"The IEEE Conference on Local Computer Networks 30th Anniversary (LCN'05)l","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125179635","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}

This combination provides a higher aggregate performance because of the cooperative cache among different target nodes. We have developed a model to analyze iPVFS.

While these protocols provide a number of benefits, including being able to pass through firewalls and are universally supported across different platforms, they were designed for wired networks with high bandwidth, low latency and low error rate transmissions. Due to the variability of wireless channels however, these assumptions do not hold in wireless environments. In this paper, we investigate the performance of HTTP and TCP as transport protocols for SOAP in wireless environments. Through extensive testing, we show that SOAP-over-HTTP and SOAP-over-TCP are inefficient and lead to high latency and transmission overhead for wireless applications. To overcome these limitations, we study the use of UDP as a binding protocol for SOAP. The results obtained are promising and show that SOAP-over-UDP provides throughput that is ten times higher compared to SOAP-over-HTTP in a wireless setting. Furthermore, using UDP to transport SOAP messages reduces transmission overhead by more than 50% compared to SOAP-over-HTTP. Finally, to illustrate where UDP binding can be useful, example applications are also described in this paper","PeriodicalId":368269,"journal":{"name":"The IEEE Conference on Local Computer Networks 30th Anniversary (LCN'05)l","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129847743","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}
