Sarangan","doi":"10.1109/AICCSA.2008.4493546","DOIUrl":"https://doi.org/10.1109/AICCSA.2008.4493546","url":null,"abstract":"One of the most critical issues in wireless sensor networks is the limited availability of energy within the network nodes. Recently, the idea of deploying a high capacity overlay using virtual sinks with long range 802.11 links to ease congestion in the underlying sensor network has been explored. Since the VSs are battery powered, it is important to conserve energy in them too. To reduce the energy consumption, usually the shortest path (SP) route is preferred in networks that do not use topology control. However, if only a few of the VS nodes are sending data, routing along the SP may require some additional VS nodes to be turned on just for the relaying purpose which otherwise could be turned off. Since the link bandwidth is high in 802.11 (Mbps) and the sensory data generation rate is low (Kbps) in comparison to the bandwidth, a high idle-mode energy cost may be incurred in the relaying VS nodes. In this paper, we explore the idea of using minimum connected dominating set (MCDS) based routes, since more energy can be saved by switching the non-dominator VSs to sleep mode and by funneling all the data through the MCDS nodes. We propose an energy-aware routing scheme that considers both the SP route and the MCDS nodes to discover a path along the VS network to the physical sink. Performance evaluation of the routing scheme shows a notable reduction in the overall energy consumption in the network with respect to SP routing while simultaneously maintaining an acceptable packet delivery rate.","PeriodicalId":234556,"journal":{"name":"2008 IEEE/ACS International Conference on Computer Systems and Applications","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114740930","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 shared nature of the transmission medium makes it challenging to fully exploit these networks. In an attempt to improve the radio resource utilization, several muting metrics have been specifically designed for wireless mesh networks. However, although some evaluations have been conducted to assess the performance of these metrics in some contrived scenarios, no overall comparison has been performed. We therefore studied the performance of the most popular routing metrics currently used in wireless mesh networks; Hop Count, Blocking Metric, Expected Tran- mission Count (ETX), Expected Transmission Tune (ETT), Modified ETX (mETX), Network Allocation Vector Count (NAVC) and Metric of Inteiference and Channel-Switching (MIC). We showed under various simulation scenarios that although all the metrics except NAVC offer the same end- to-end delay and packet loss ratio, differences can he distinguished in terms of traffic load repartition. In particular, the congestion-avoidance strategies of ETX, mETX, and MIC prevent the starvation of flows following longer paths and consequently provide a more uniform traffic repartition.","PeriodicalId":234556,"journal":{"name":"2008 IEEE/ACS International Conference on Computer Systems and Applications","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127368823","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 programs can vary significantly in size and complexity. Any kind of reliability program, like a preventive maintenance (PM) program, consists always of one or more reliability models and reliability data to execute these models. It is needless to say that the actual successful implementation and utilization of these reliability programs heavily depends on the accuracy of the reliability models and the availability of realistic data, or at least as close as possible data. The objective of this paper is to give the reader a better understanding of the importance of reliability engineering for the purpose of process availability, safety and preventive maintenance programs. The paper will first explain what reliability engineering is and why it is important for processing plants to have a reliability program followed with an overview of different programs in use by companies today (Preventive maintenance, risk based inspections, etc).","PeriodicalId":234556,"journal":{"name":"2008 IEEE/ACS International Conference on Computer Systems and Applications","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123633783","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}

Worldwide Interoperability for Microwave Access (WiMAX) comes at a time when the need to communicate is at its highest. Designed to provide throughput similar to that of wired networks, WiMAX wireless and mobility features promises hope to underserved areas. WiMAX Mesh topology connects subscribers to the Internet without being connected to the Base Station (BS). Without relying on basic infrastructure like roads, tunnels or network backbones, WiMAX mesh will provide answers to long existing connectivity demands for underserved areas. This paper proposes a different approach, one that will lower the subscriber's cost and hence help to bridge the divide by using communities to set mesh networks and eliminate the 'middleman'. It provides insight into WiMAX, citing its mesh capabilities as the key-enabling factor in bridging the divide. The results found from a survey conducted about the problems facing developing countries are incorporated and used to show how this topology will suite developing countries' environments.","PeriodicalId":234556,"journal":{"name":"2008 IEEE/ACS International Conference on Computer Systems and Applications","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132808868","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}
