WSN中覆盖空洞修复研究介绍

Introduction to the Study of Coverage Hole Repair in WSN *

在无线传感器网络中,节点分布不均匀,节点在采集和传输数据时能耗不均衡,以及节点在运行过程中出现故障等原因,均会导致网络覆盖率降低,造成覆盖空洞,从而产生异常的网络数据。为了提高网络覆盖率并延长网络寿命,需要对覆盖空洞进行测试与修补。为此,对现有网络覆盖方法进行分类整理,同时罗列出覆盖评价的重要性能指标,以供该领域参考。

In wireless sensor networks,the uneven distribution of nodes,the uneven energy consumption of nodes in data collection and transmission,and the failure of nodes in the operation process all lead to the reduction of network coverage,resulting in the coverage of holes and abnormal network data.To improve network coverage and extend network lifetime,it is necessary to test and repair the coverage voids.To this end,the existing network coverage methods are classified and organized,and the important performance indicators of coverage evaluation are listed for reference in this field.
