This paper analyses the impact of hops changing in mobile ad hoc network on the performance of TCP Vegas, and presents a new algorithm named TCP Vegas-HA (TCP Vegas — Hops Adaptive) to improve the performance of TCP Vegas in mobile ad hoc network. As the minimum round-trip time (baseRTT) cannot be accurately measured in mobile ad hoc network, a new measurement method using the empirical value is proposed. Simulation results show that the algorithm has good adaptability with route buffers changing while hops varies, and can effectively increase the TCP Vegas throughput in mobile ad hoc network.","PeriodicalId":386083,"journal":{"name":"2011 International Conference on Mechatronic Science, Electric Engineering and Computer (MEC)","volume":" 610","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120827521","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}

Firstly the precision localization of the target is realized by wavelet which has the characteristics of multi-resolution analysis and time-frequency local window analysis, then the coordinate of center-of-mass is calculated based on the detected initial frames, and the result is regarded as the initial position of the improved Camshift algorithm. Then the Kalman filter algorithm is combined with Camshift in order to adjust the center-of-mass position of moving target.
