摘要
针对现有无线传感器网络(WSN)空洞覆盖方案没有考虑监控质量(MQ)的差异性问题,提出一种基于节点移动和监控质量感知的WSN覆盖方案.首先,将网络构建成六边形网格结构.然后,移动传感器根据邻居单元的监控情况进行移动,并根据单元的MQ需求和节点能量适当调整移动路线,同时避免覆盖冗余.最后,形成能够实现WSN全时间和空间覆盖的支持路径.实验结果表明,该方案能够均衡节点能耗,最大化网络的完整覆盖时间,提高网络的生命周期.
For the issues that the existing wireless sensor network(WSN)hole coverage scheme has not considered the difference between monitoring quality(MQ),a WSN coverage scheme based on mobile node and quality of monitoring aware is proposed.First,the network is constructed into a hexagonal grid structure.Then,this scheme moved the mobile sensor according to the monitoring situation of the neighbor unit,and adjusted moving route according to the MQ requirement of the unit and the node energy,at the same time avoid covering redundancy.Finally,it formed the support path to achieve WSN full time and space coverage.The experiment results show that the proposed scheme can balance the energy consumption of the nodes,maximize the complete coverage of the network,and improve the life cycle of the network.
