A distributed adaptive sensor network considers spatio-temporal challenges simultaneously. To analyze diffusion networks under TVAR modeling problem circumstances, we investigate and elaborate on their performance under non-stationary conditions. Different versions of diffusion networks are then theoretically compared under the problem conditions. Furthermore, their superiority to single point observations is shown. Finally, the proposed algorithms are implemented on a raw and real sensor network dataset recorded from moving vehicles. The experimental results well support the theoretical findings, and demonstrate the excellence and efficacy of distributed diffusion adaptive networks for this case.","PeriodicalId":199393,"journal":{"name":"2014 9th International Symposium on Communication Systems, Networks & Digital Sign (CSNDSP)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117270215","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 protocol the radius of virtual circles and the size of clusters would be increased by the distance to base station (BS) and, therefore, the size of clusters are different. In each cluster, the leader nodes are responsible for aggregating data from ordinary nodes and sending them to cluster heads. Simulation results demonstrate that proposed protocol increases the network lifetime over 73% and 21% comparing to LEACH and DSBCA protocols.","PeriodicalId":199393,"journal":{"name":"2014 9th International Symposium on Communication Systems, Networks & Digital Sign (CSNDSP)","volume":"1998 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128254991","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}

The filters are synthesized using Cadence RTL compiler in UMC 90 nm technology. The performance of the filters are compared in terms of Area (A), Power (P), and Delay (T). The results show that the proposed architecture offers significant improvement in terms of area, delay and area-delay product(AT).

This paper describes a novel mixed signal scheme which incorporates detection of both lock and out-of-lock conditions of a PLL. The scheme covers integer and fractional PLL modes of operations and programmable to generate lock condition to a very high accuracy.

For this purpose, we formulate the problem as a stochastic linear programming (SLP) problem. Then, we transform this model into equivalent deterministic Second-Order Cone Programming (SOCP) problems. All models are intended to maximize the bit rates throughput of the network subject to subcarrier and power user constraints. Our preliminary numerical results show that the joint chance constraint formulation is slightly conservative than the individual probabilistic one. Finally, we show that our approximation of the deterministic joint probabilistic model is very tight.","PeriodicalId":199393,"journal":{"name":"2014 9th International Symposium on Communication Systems, Networks & Digital Sign (CSNDSP)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117091392","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}

Due to the analyte binding to the sensing holes, the refractive index of holes is changed and consequently the resonant wavelength is shifted. According to the results, the resonant wavelength shift in the range of 1.33-1.55 is linear with respect to the refractive index variations.
