But we have to consider the coverage of heterogeneous nodes because of actual application. This paper presents a Coverage-Enhancing Algorithm for Heterogeneous Sensor Networks. We design the sensing model of heterogeneous nodes based on their characteristics, analyze and define the coverage problem on the basis of the model, demonstrate how to maximize the coverage in ideal state, and enhance the entire coverage of heterogeneous network. Simulations show the validity of the algorithm.","PeriodicalId":206575,"journal":{"name":"2009 IEEE International Conference on Intelligent Computing and Intelligent Systems","volume":"56 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132604360","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 dynamic model of the tethered satellite is established. The deploy method for short tethered satellite is discussed. The dynamic characters of the system in the developing phase are analyzed. The subsatellite could be deployed to directions other than the vertical direction with an initial velocity. Fuzzy control scheme is designed considering the precision of the tether direction and the output character of the thrusters. The fuzzy control system can keep the sub-satellite in the ideal direction. The angles of the tether are within 0.5deg from the ideal values and angular velocity is within 0.03deg/s during the developing period. Thrusters do not need to work frequently. Numerical simulation testified the efficiency of the system.","PeriodicalId":206575,"journal":{"name":"2009 IEEE International Conference on Intelligent Computing and Intelligent Systems","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130808425","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}
