摘要: 在实际的无线传感器网络中,由于路由空洞而采用的边缘转发方式容易引起空洞边缘节点能量消耗过快从而导致空洞不断扩大,形成能量空洞。为延长网络生命周期,避免能量空洞的出现,对网络中的盲区、盲点进行定义,设计一种盲区查找规则,并提出一种基于盲点查找的路由算法。利用网络中的盲点和盲区信息进行路由,避开空洞边缘的盲点,从而减少了边缘转发次数。仿真结果表明,与GPSR和GEAR算法相比,该算法能有效延长网络生命周期,数据包到达率较高,传输效率有所提升。

Abstract: In the actual Wireless Sensor Network(WSN),the perimeter forwarding method can easily cause the hole edge nodes’ energy consumption to be too fast because of the routing void,resulting in the expansion of the void,and the formation of energy holes.In order to prolong the network lifetime,and avoid energy hole,this paper defines the blind area and the blind node,designs blind area search rules,and proposes a routing algorithm based on blind node search.This paper uses the blind node and blind area information in the network to route,thus avoiding the blind node of the hole edge,and reducing the frequency of using perimeter forwarding.Simulation results show that compared with GPSR and GEAR,this algorithm can effectively prolong the network lifetime,and also improve the performance of packet delivery rate and transmission efficiency.
