摘要:

栅栏覆盖是近年来无线传感器网络的研究热点之一,如何延长生存周期是无线传感器网络研究的一个重要问题。针对无线传感器网络的栅栏覆盖应用,设计了两种最大化网络生存周期的调度算法:集中式的Greedy调度算法和分布式的DBCS调度算法。仿真实验表明:两种算法显著地延长了网络的生存周期;在较稀疏的网络中,DBCS算法与Greedy算法性能接近,分布式的DBCS算法适合应用于大规模传感器网络。

Abstract:

arrier coverage has attracted much attention in wireless sensor network recently,and it is a very important problem that how to prolong the network life time.We devise two scheduling algorithms to maximize the network life time for barrier coverage:Greedy algorithm and DBCS (Distributed Barrier Coverage Scheduling) algorithm.Comprehensive simulation demonstrates that: (1) the two algorithms can prolong the network lifetime effectively;(2) the performance of DBCS is close to that of Greedy when the network is sparse,and (3) the DBCS is applicable for large scale sensor networks.
