基于定向移动的水下传感器网络覆盖算法
Coverage Algorithm Based on Fixed-directional Movement for Underwater Sensor Network
摘要
Abstract
The coverage is a fundamental issue and an important indicator of the service quality in Wireless Sensor Network ( WSN ) . For three-dimensional underwater sensor network model, an virtual force algorithm based on directional movement is proposed that simplifies virtual force as the repulsion force only by neighboring nodes. This paper defines the ideal position relatively of the two nodes’ position while one of sensing spheres of two neighboring nodes is tangent to the other. Virtual force is proportional to the distance moved from original position to the ideal position. The movement distance is determined by the resultant of virtual force which acts on the node. Experimental results show that the algorithm can effectively optimize the layout of underwater sensor networks and improve the network’ s coverage rate.关键词
