摘要

本文提出了一种新的路由方案——基于合作分集的路由(Cooperative diversity based routing, CDR)，该方案利用协作空间分集来节省无线自组网的功耗和提高无线自组网的性能。基于Haenggi的链路模型，分析了CDR路由的端到端性能。用分析方法对改进后的性能与多跳中继路由(MRR)进行了比较。在具有7个节点的ad-hoc网络中，当目标节点所需的中断概率为1times10-3时，我们注意到，与MRR相比，使用我们提出的CDR，每个节点平均可以节省21.5 dB的功耗。

Wireless Ad-hoc Networks Using Cooperative Diversity-based Routing in Fading Channel

We propose new routing scheme, Cooperative Diversity-based Routing (CDR) which utilize the cooperative space diversity for power saving and for performance enhancement of wireless ad-hoc networks. The end-to-end performance of the proposed routing, CDR, is analyzed based on the Haenggi's link model. The improved performance is compared with Multi-hop Relay Routing (MRR) by analytical methods. When the required outage probability is 1times10-3 at the destination node in ad-hoc networks with 7 nodes, we noticed that each node can save power consumption by 21.5 dB in average, by using our proposed CDR compared to MRR.
