无线传感网络中协作分集路由协议的研究

在无线传感网络系统中,协作分集是对抗多径传播引起的信道衰落的一种有利的方法,但是目前大多数协作分集的研究集中在物理层,协作引入后对于网络的更高层的影响并没有很好的展开讨论。基于协作分集中协作路由协议是一个新的研究领域,介绍了协作分集以及GeRaF和GnRaF两种协作路由协议。这两种协议摒除了传统路由协议依靠拓扑信息和路由表的弊端而是只根据节点自身及周围节点的地理位置信息及角度信息的新型路由协议。

Study of Cooperative Diversity Routing Protocol in Wireless Densor Networks

Because of the multipath fading channel of communication caused serious influence can be produced through diversity effectively solved in wireless sensor networks system.Cooperation is the diversity of decline against a favorable channel,but most current cooperative communication research focuses on the physical layer,after introducing the cooperation for network and no more high-level debate is very well.Based on the cooperative points on cooperation routing protocol is a new research field,and the existing research shows that can greatly reduce the self-organization network energy consumption,it is very suitable for energy resources WSN.This diversity is introduced the GeRaF and the GnRaF and cooperation,coordination routing protocols and give to the simulation analysis and results.
