In this paper we propose a remote health care monitoring system that uses sensor networks to extend the coverage of medical application to underserved area. We delineate the challenges that face researchers in this area. In addition, the paper describes the general architecture and proposes a MAC scheme for healthcare sensor networks (MACH) that adapts channel provisioning based on the information criticality. MACH enables emergency traffic to meet its quality of service (QoS) requirements. Performance evaluation using analytical modeling shows that our proposed MAC give preference to emergency traffic which is crucial for medical applications.","PeriodicalId":410786,"journal":{"name":"2008 IEEE Region 5 Conference","volume":"80 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130136531","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 standard TEM cell was modified with a double-ended monopole antenna as a signal leader for incoming and outgoing signals between the TEM cell's outer surface. The electric field distribution was studied with parameters such as the cellular phone position, polarization, dialing type, and dialing frequency. The field uniformity can be improved with either the use of a shorter signal leader or the TEM cell with a reduction in size. It also showed a good agreement between the results from experiments and simulations. With the proposed exposure technique, the Specific Absorption Rate (SAR) result from simulation also indicated the energy absorption by the test sample, confirming a potential usage of the proposed setup in studies related to biological applications.","PeriodicalId":410786,"journal":{"name":"2008 IEEE Region 5 Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130843975","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}

Our new constellation doubles the number of points available for data transmission without decreasing the distance between points or increasing energy, and may therefore be used in a trellis coded modulation (TCM) system without constellation expansion penalty. Because the new constellation has constant envelope, the modulation scheme becomes very attractive for nonlinear channels such as the magnetic recording channel or the satellite channel with traveling wave tube amplifiers.","PeriodicalId":410786,"journal":{"name":"2008 IEEE Region 5 Conference","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122479513","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}

An effort has been done to determine the best value of the number of unrolled loops to implement the RC5 algorithm using 192-bit encryption key. The various models tested were based on single-custom processor with: no-loop-unrolling; loop unrolled implementations with different unrolling sizes. In this research, various performance measures are considered, such as the maximum frequency of operation, circuit size, throughput, and energy consumption. To achieve proper comparison results, all models were developed and mapped to the same hardware reconfigurable chip, a Field Programmable Gate Array (FPGA). The performance parameters of each model were evaluated to determine the best hardware model. Verilog hardware description language was used to model and test all implementations. While no-loop-unrolling provided the least circuit size, the 3-loop-unrolled approach provided the highest throughput, amongst all tested implementations. A throughput speed up of 24% was achieved compared to a reference system implemented in a different target device using a Xilinx FPGA family. Comparing our implementations on the same Altera FPGA family, a maximum throughput speed up of 50% was achieved.","PeriodicalId":410786,"journal":{"name":"2008 IEEE Region 5 Conference","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114483131","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}
