| Abstract: | By importing mobile sensors and corresponding relocalization algorithms into the wireless sensor networks,problems of further investigation,sensor failure and inaccurate deployment of sensor can be solved. Algorithms for the relocalization of the mobile sensors are introduced in three kinds which are moving to the region of interests for further investigation,expanding coverage area and healing the coverage holes,based on the aim of the moving of mobile sensors.The corresponding main solutions models and future research directions are also summarized and analyzed. |
