无线传感器网络节点部署优化及链路质量评估

Node Deployment Optimization and Link Quality Evaluation in Wireless Sensor Network

本文运用虚拟力算法对三种不同初始化节点分布进行优化,并且从链路质量评估值(LQA)和覆盖率角度对不同初始化部署的节点布局进行评估。研究结果表明,WSN节点在虚拟力算法作用下,圆环分布比平均分布能在迭代次数较少的情况下,达到网络最大覆盖率,并且此刻LQA值最大,网络通信质量较高,从而节省了能耗和资源,更具有一定的实用价值。

This paper utilizes virtual force algorithm to optimize three different initial node distributions, and analyzes the different initial deployment nodes based on the point of link quality evaluation value （LQA） and the rate of coverage. The results show that for the WSN nodes under the virtual force algorithm, the ring distribution can achieve network maximum coverage and maximum LQA value than the average distribution, even in the circumstances of less iteration. The network communication quality is high, and saves energy as well as resources, so it has certain practical value.
