This paper also design semi- physical simulation platform based on software receiver structure, which integrate GPS receiver and WSN nodes. Pseudorange observation data of global positioning system (GPS) and distance observation data of WSN are utilized to carry out positioning. Simulation results show that comparing with traditional GPS location algorithm, adaptation range is increased and positioning with less than four satellites is realized using the algorithm; and comparing with WSN location algorithm, the algorithm has a higher precision.","PeriodicalId":228533,"journal":{"name":"2008 International Symposium on Computer Science and Computational Technology","volume":"246 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122133345","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}

Keeping only a portion of nodes active and putting the others into sleep mode can conserve energy. In order to maintain satisfactory data quality, we recover the would-be sensed data for sleeping nodes. In this paper, we exploit spatial correlation among densely deployed nodes and use such correlation for data recovery. Loss in data quality caused by data recovery is the criterion for our proposed polynomial-time active nodes selection algorithm. Considering the possible energy consumption unbalance, we further develop a multi-shift scheduling scheme. The multi-shift scheduling is formulated as a constrained mini-max optimization problem. We validate these algorithms using a real-world data set and observe very satisfactory results.","PeriodicalId":228533,"journal":{"name":"2008 International Symposium on Computer Science and Computational Technology","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129770270","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}

This paper thus proposed an effective method to improve the drawback, which is mainly based on gray value moment features of normalized block and related inequality is presented by the authors. During the search process, the gray value moment features is first utilized to confine efficiently the search space to the vicinity of the initial-matched block (i.e., the domain block having the closest gray value moment features to the input range block being encoded), aiming at reducing the searching scope of similarity matching to accelerate the encoding process. Simulation results show that the proposed scheme not only reduce the searching scope of best-matched to accelerate the encoding process, but also can obtain good quality of the reconstructed images as compared to the baseline algorithm with full search.","PeriodicalId":228533,"journal":{"name":"2008 International Symposium on Computer Science and Computational Technology","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130617209","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}
