【摘要】：提出一种基于代理和环形路由的传感器网络覆盖空洞修复策略。此策略的核心在于:每一个休眠节点选取距离自己最近的工作节点作为代理节点,以代理节点与网络几何中心的连线方向扩散其位置信息,形成纵穿网络的存储代理信息的扩散路径;当网络中工作节点濒临死亡时,从代理节点开始以网络几何中心为圆心进行绕环路由,定位替换节点;经过仔细规划对信息路由的剪枝规则,降低节点的存储信息量。通过理论与仿真实验对网络能耗、节点移动距离和节点存储容量等多个方面对修复算法进行分析、评价与实验。研究结果表明:本文提出的策略有利于降低网络能耗,提高节点存储容量。
[Abstract]:An overlay hole repair strategy for sensor networks based on proxy and ring routing is proposed. The core of this strategy is that each dormant node selects the nearest working node as the proxy node. The location information is diffused in the direction of the connection between the agent node and the geometric center of the network, and the diffusion path of the storage agent information of the network is formed. When the working node in the network is on the verge of death, Starting from the proxy node, the center of the network geometry is used as the center of the loop to locate and replace the node. After carefully planning the pruning rules for the information routing, the storage information of the node is reduced, and the energy consumption of the network is analyzed through theoretical and simulation experiments. The algorithm is analyzed, evaluated and tested from several aspects, such as node moving distance and node storage capacity. The results show that the proposed strategy is beneficial to reduce network energy consumption and improve node storage capacity.
