Despite their use in interesting applications, such as healthcare and surveillance, many shortcomings derived from their small size and constrained batteries limit their use, calling for solutions to enhance the WSNs. Born in wireless networks using the transport control protocol (TCP), cross-layer proposals have been proving that there is interdependency of parameters across the layers and that collaboration among the layers of the protocol stack can improve the performance of wireless networks in terms of quality of service, throughput, and transmission fairness. Thus, cross-layer design is merging into WSNs, especially to reduce sensors energy consumption. In this work, a cross-layer sleep and rate adaptation mechanism is proposed to operate on a slotted ALOHA WSN. Through the use of sensors sleep periods, energy consumption is reduced, and throughput reduction is mitigated by the use of the rate adaptation.","PeriodicalId":149198,"journal":{"name":"2010 International Conference on Information and Communication Technology Convergence (ICTC)","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116319126","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 this paper, we discuss some of the bit loading algorithms, compare them with respect to their BER performance, and present an effective concise Adaptive Grouped Loading (AGL) algorithm. In particular, we consider the bit loading in near optimal Singular Value Decomposition (SVD) based MIMO-OFDM system. While using SVD based system, the system requires the perfect Channel State Information (CSI) of channel transfer function at the transmitter. This scenario of SVD can be taken as an ideal case for the comparison of loading algorithms and to show the actual enhancement achievable by our AGL algorithm. Irrespective of the CSI requirement imposed by the mode of the system itself, ABL demands high level of feedback requirement. Grouped Loading (GL) would reduce the feedback requirement depending upon the group size. However, this also leads to considerable degradation in BER performance. In our AGL algorithm, a group is formed with a number of consecutive sub-channels belonging to same transmit antenna, with individual gains falling under predefined criteria. Simulation results show that the proposed AGL requires much lesser CSI compared to GL for same BER performance margin.","PeriodicalId":149198,"journal":{"name":"2010 International Conference on Information and Communication Technology Convergence (ICTC)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123661918","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}
