Anti-Monitoring Algorithm Based on Model of Sensing Circle in WSN
The paper studies on the calculation method for safe path of moving objects in sensor environment so as to realize anti-monitoring. It presents a concept of sensing circle on which a new method is designed for determining the candidate set of the next location points. Then it improves the A heuristic path searching algorithm on which a new shortest anti-monitoring path searching algorithm is designed based on local information. Theoretical analysis and experimental results show that the new algorithm has less computational complexity, the calculated safe path is shorter, and the search range is significantly narrowed. In addition, this is a fully distributed algorithm with good usability since it requires only the moving objects sensing local information within their detective radius.
