摘要

在SITE（信息技术与工程学院）算法基础上

提出了ADDM（基于邻居节点平均距离的网络覆盖判别模型）算法

通过计算所有邻居节点与本节点的平均距离和交叠区域的圆心角来判别该节点是否为冗余节点。理论分析与仿真实验表明

ADDM算法较大地改善了SITE算法

成功解决了SITE算法没有考虑距离大于感知半径的节点对覆盖冗余贡献的问题

从而用更少的节点实现了区域的覆盖

节省了网络节点的活动数目

延长了网络的生存时间。

Abstract

On the basis of the SITE algorithm

this paper proposes a node coverage discrimination model based on the average distance of neighbor nodes（ADDM）for wireless sensor networks

which discriminate whether a certain node is redundant or not by computing the average distance between this node and all the neighbor nodes and the central angle of the overlapping area.Theoretical analysis and simulation results show that the ADDM improves the SITE algorithm

overcomes its failure to consider the contribution of those nodes with distances longer than radius of perception in covering redundant nodes

thus realizing the regional coverage with fewer nodes

reducing the number of active network nodes and prolonging the network life time.
