为了提高无线传感网络节点的覆盖率,防止网络“空洞”的出现,提出一种基于虚拟力的无线传感网络节点覆盖策略。首先分析了无线传感器网络的结构和能耗模型,构建了传感器节点的覆盖模型;然后建立了传感器节点与锚节点以及传感器节点之间的虚拟力模型,并采用粒子群算法模拟节点的移动过程,最后通过仿真测试其性能。仿真结果表明,基于虚拟力的无线传感网络节点覆盖策略可以实现传感器节点的合理部署,提高了无线传感器网络的有效覆盖率。
In order to improve the coverage of wireless sensor network nodes and prevent the appearance of network “void ”, a virtual force based wireless sensor network node coverage strategy is proposed. Firstly, the structure and energy consumption model of wireless sensor network are analyzed and the coverage model of sensor node is constructed. Then, the virtual force model between sensor node and anchor node and sensor node is established. Particle swarm optimization algorithm is used to simulate the moving process of node, Finally, through the simulation test its performance. The simulation results show that the wireless sensor network node coverage strategy based on virtual force can realize the rational deployment of sensor nodes and improve the effective coverage of wireless sensor networks.
