Especially, in a mobile peer-to-peer (P2P) system, if a mobile device uses all its energy up, it can no longer participate in the system. Furthermore, as the number of peers without energy increases, so does the file search failure rate of the system. In this paper we present an energy-effective routing protocol in a double-layered P2P system that consists of peers in the upper level, called super peers, and other peers in the lower level, called subpeers. The double-layered system allows file searches with much less message traffics compared with a `single-layered' P2P system by forcing the file searches to be taken among super peers and hence can avoid flooding in the entire network. We introduce two schemes to improve the average lifetime of a network. Functionality and performance were evaluated through various experiments, and the results showed that the protocol combining the proposed schemes improved the average network lifetime by up to 146%","PeriodicalId":383593,"journal":{"name":"2009 4th International Symposium on Wireless Pervasive Computing","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116146051","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}

These key topics strictly related to each other are of high importance for building and maintaining reliable and long-lasting WSN applications. However, almost none of the researches have been previously focused on them together, prompting the idea and the presented work to integrate an energy-aware and delay-sensitive centralized MAC (e.g., the EDCMAC) protocol for WSNs and contemporary encryption methods. In the simulation studies, superiority of using the SEA to the traditional AES and Skipjack has been concluded as providing much more protected data transfer and improving life-time and delay performance of the WSN applications.","PeriodicalId":383593,"journal":{"name":"2009 4th International Symposium on Wireless Pervasive Computing","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123596425","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}

TelegraphCQ is an open source DSMS tool developed towards handling live streams of data.

It involves a data analysis algorithm running on the user device, and Internet servers that retrieve the data from the user, merge them, and send them back to the community. Such a system is meant to be accessed by a large number of users, and has to be fast-responsive enough to deal with all the requests; hence, provisions must be made for effective live stream handling.

However, with only a limited number of channels available, the problem of increased interference can severely degrade the performance of WLANs if an effective channel assignment scheme is not employed. Previous studies on channel assignment in WLANs almost always assume that all access points (AP) employ the same channel assignment scheme which is clearly unrealistic. On the other hand, to the best of our knowledge, the interaction between different channel assignment schemes has also not been studied before. Therefore, in this paper, we investigate the effectiveness of our earlier proposed asynchronous channel assignment scheme in these heterogeneous WLANs scenarios. Simulation results show that our proposed scheme is still able to provide robust performance gains even in these scenarios.","PeriodicalId":383593,"journal":{"name":"2009 4th International Symposium on Wireless Pervasive Computing","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129910219","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}

Each mobile sink needs to periodically update its location information into the sensor network. Due to multiple mobile sinks, frequent location updates are needed and this causes enormous consumption of the limited battery power in the sensor node. Several routing protocols, such as TTDD and SEAD, suggest hierarchical approach for supporting mobile sinks. These approaches, however, build the grid structure or the tree per event which causes much power consumption as well, so they are not suitable for the sensor network where the event frequently happens. To effectively send the data to multiple mobile sinks and minimize the battery power consumption of sensors, we propose a Grid-Based Energy-Efficient Routing protocol(GBEER) which makes only one grid structure independent of the event. We adopt a Grid-Quorum solution to effectively advertise and request the data for mobile sinks. Simulation results show that GBEER outperforms TTDD in terms of total energy consumption with variation of the number of sinks and sources and mobile sinks' speeds.","PeriodicalId":383593,"journal":{"name":"2009 4th International Symposium on Wireless Pervasive Computing","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121435121","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 general principle of these end-to-end TCP enhancement schemes is to distinguish wireless loss from congestion loss, and to take the cause of the loss into consideration when performing TCP congestion control. However, they do not consider the ratio of congestion losses to wireless losses which significantly affects their performance, mainly in terms of their throughputs. In this paper, a new approach has been developed to address this issue. To apply the approach into an end-to-end TCP enhancement scheme, the ratio of congestion losses to wireless losses are estimated and the parameters used in the scheme are adjusted to further improve its performance. The simulation experiments showed that Veno, a popular end-to-end TCP enhancement scheme, with the new approach always outperformed the original Veno in terms of throughput and fairness, and their differences could be more than two times better.","PeriodicalId":383593,"journal":{"name":"2009 4th International Symposium on Wireless Pervasive Computing","volume":"118 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116688780","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}
