摘要
覆盖空洞的出现会降低网络的通信性能,往往当网络失效后监控区域仍然存在大量的冗余节点。因此如何利用监控区域中剩余的冗余节点修复覆盖空洞也是空洞修复方面的研究热点。为了解决这一问题,提出了一种通过计算空洞边缘节点与其邻居冗余节点关键值的策略进行覆盖空洞的修复。仿真实验表明该算法同DAAHP算法相比较,在覆盖空洞修复率、激活的冗余节点数目以及冗余节点利用率方面都具有优势。
The coverage holes would reduce the communication performance of network, there are still a large number of redundant nodes in the monitoring area when network failure. So how to make use of the rest of the redundant nodes in monitoring area to repair coverage holes had been hot spot re- search. In order to solve this problem, this paper has proposed a strategy that calculate the key values of between hole edge node with its neighbor redundant nodes to repair coverage holes. Simulation re- suits show that, compared with DAAHP algorithm, this algorithm has higher advantage in network coverage rate, the number of active redundant nodes and the utilization of active redundant nodes.
