| Wireless sensor networks are a kind of network which a lot of sensors interrelate, process and transmit information with each other through wireless communications. External uncertainty environment often leads to hundreds of sensors shall be deploymented to work together, so the large-scale sensor networks research is gradually aroused widespread interest and considered a challenging research topic of this century. Against the above problems, the academic research mainly concentrated in the sensor clustering algorithm, communications routing protocols, network coverage and sensor sensor data fusion technology.This paper focus on the other side of sensor functionality, namely anti-monitoring.Based on traditional anti-monitoring algorithm, proposed a new partition topologoy and utilize heuristic path searchring algorithm to implement anti-monitroing algorithm, therefore it is flexible to centralized and distributed scence.Compared to conventional works, it outstand in performance.The contents of this article are as following:(1) The background outline of the subject both national and international.(2) The analysis of traditional partition model with DIJKSTRA algorithm based anti-montoring algorithm(3) Improve anti-monitoring performance by utilizing secure-circle model.(4) Improve tradition circle grid by eight neigbors grid, and adpot A* heuristic algorithm.(5) Design a simulation experimental platform by JAVA language, to demensrate the sensor distribution and the anti monitoring path of the mobile object driven by different algorithm. At the same time, the program is capable of adjusting the parameters of the anti-monitoring algorithms to analyze the performance in all aspects.(6) Make an evaluation of these algorihms and summeraize them. |
