改进的非均匀有向传感器网络节点部署方法

在无线传感器网络的相关研究中，有向传感器网络DSNs（Directional Sensor Networks）由于在节点属性上增设了有向属性而使其拥有更为广阔的实用意义。针对重点区域覆盖不足的问题，提出了一种改进的非均匀有向传感器网络节点部署方法，引入部署中心和矢量引力的概念，增加斥力的非均匀部署属性，从而加强区域内的覆盖质量。通过实验对比表明，改进后的部署方法在有效节点数量及覆盖率方面均优于一般的有向传感器网络节点部署方法。

Improved Approach to Deploying in Non-uniform Distributed Directional Sensor Networks

In various related research in Wireless Sensor Networks,Directional Sensor Networks(DSNs)due to the additional attribute on the sensor attributes to make them have a wider range of practical applications. For the problem of insufficient coverage of key areas,presents Potential Field based Non-uniform Distribution Algorithm (PFNDA),introducing concepts of The Key Center and The Vector Gravity. It also introduced a non-uniform de?ployment repulsion properties,strengthen coverage quality within the region. The contrast experiments show that the improved deployment method is better than the average directional sensor network node deployment method in the effective number of nodes and coverage rate.
