Survey of topology control in wireless sensor networks

GAN Cong-hui,ZHENG Guo-qiang,TANG Sheng-yu(Electronic Information Engineering College,Henan University of Science & Technology,Luoyang Henan 471003,China)  
As a vital supporting technology in WSNs,topology control can reduce redundancy and prolong network lifetime on the premise of network coverage and connectivity.This paper discussed the target of topology control,studied topology control models in WSNs and typical algorithms with the application of random graph theory,made comparative study of the characteristics of topology control mechanism on the basis of different classifications of network structure,and explored the relations among topology control,connectivity and scheduling in WSNs.Finally,it summarized the present situation and problems which still remained to be solved.
