战场环境中无线传感器网络路由协议研究
首发时间:2011-04-20
摘要:高安全性、低能耗以及较长的网络寿命,可以说是战场环境中无线传感器网络(Wireless Sensor Network,WSN)路由协议最为关键的设计目标。本文在引入节点地理位置信息并综合LEACH路由协议和两种地理位置路由协议GAF和GPSR算法优点的基础上,提出一种更加适合于战场环境的无线传感器网络路由协议-GP-LEACH协议。该协议通过地理位置信息识别节点真伪,并以此来增强网络安全性;在网络分区阶段,按照GAF算法的分区思想对网络进行分区;在建立的虚拟网络的每一个小区域内按照LEACH路由算法选出该区域的簇首节点;采取GPSR算法中的贪婪转发和周界转发两种分组转发方式对节点数据和信息进行转发。通过仿真表明,该算法能够延长网络生存时间、降低网络能耗并有效增强网络安全,适用于复杂的战场环境。

Study of WSN routing protocols in the Battlefield environment
Abstract:IIn this paper,a better and more suitable routing protocol for battlefield environment wireless sensor network is be found.This routing protocol is GS-LEACH.and it's found by analysis and improve the Existing wireless sensor network routing protocol. In the stage of network partition, the GAF algorithm according to the division of network by partition. Thoughts Establishing virtual network in every small area LEACH routing algorithm according to choose the regional cluster head node. Take GPSR algorithm in greed forwarding and perimeter forwarding two groups of nodes forward way forward data and information. Through the simulation shows that this algorithm can effectively enhance the network security and reduce the network energy, prolong the network lifetime, suitable for complex battlefield environment
Keywords: Wireless Sensor Network Battlefield environment LEACH Geographical location information
