基于几何方法的分布式无线传感器网络边界节点识别算法研究
Research on Boundary Node Recognition Algorithm of Distributed Wireless Sensor Networks Based on Geometric Method
摘要
Abstract
Regarding the problems in detecting boundary nodes,such as the strict requirement for node density,the dependence on node position,and low accuracy of identification,a distributed algorithm for detecting boundary nodes based on geometric method was proposed by analyzing the structural character of the coverage holes in wireless sensor networks and the key factors affecting the preciseness of node detection.The proposed algorithm can identify the boundary nodes of wireless sensor networks with high accuracy and low energy consumption by means of utilizing the information about absolute angles and two-hop neighbors.The simulation based on MATLAB shows that the energy consumption is effec-tively lowered with the average identification accuracy being higher than 92% and the false detection lower than 6%,which can be effectively applied into node coverage in wireless sensor networks and healing coverage holes.关键词
