多障碍的有向异构传感器网络覆盖优化算法
Coverage optimization algorithm of directional heterogeneous networks in multi-obstacle
摘要
Abstract
For the problem of coverage in heterogeneous sensor networks with multiple obstacles, this paper introduces a virtual potential field based coverage algorithm of multi-obstacle for directional heterogeneous networks(PCMODH)on the basis of the directional sensing model. Through involving the concepts of overlapping centroid, effective centroid and virtual boundary centroid, this algorithm makes optimizations of perform virtual force, node movements, boundary node and obstacle node in directional heterogeneous networks with multiple obstacles. The algorithm optimizes the coverage problem in random deployment, and increases coverage in heterogeneous sensor networks with multiple obstacles. Simula-tion results show the effectiveness of the proposed algorithm.关键词
