无线视频传感器网络有向感知K覆盖控制算法研究
Research on Directional K-Coverage Control Algorithm for Wireless Video Sensor Networks
摘要
Abstract
Abstract:As a hot topic of Wireless Video Sensor Networks (WVSNs),directional coverage algorithms have aroused extensive attention by many researchers;however,K directional coverage problem has not been studied in-depth.Due the K directional coverage problem is NP-complete problem,it is difficult to get to solve in polynomial time.This paper designed a distributed heuristic algorithm within one-hop neighbor,which obtains perceived direction of the directional sensor nodes by cooperative scheduling,so as to maximize the total time which targets are covered by at least K directional sensor nodes.Finally,the simulation results verified the coverage performance of the proposed DS-K-Coverage algorithm exceeding Greedy-Algorithm and Random-Coverage algorithm.关键词
