一种基于消息缓存的多跳协作机制
摘要
提出一种基于消息缓存的多跳协作机制(ICC机制)
该机制不需要依靠准确的网络状态信息和复杂的协作节点选择算法
而是通过利用RTS/CTS交互消息获得相隔两跳的节点MAC地址
并在数据帧中添加下两跳的节点MAC地址
使得相隔两跳的节点可靠的接收到节点发送的信号
并对接收到的信号进行合并
从而获得分集为2的增益。
Abstract
A new mechanism based on Information Cache with Multi-hop Cooperation(ICC) for wireless networks was proposed in this paper. The ICC does not depend on the network state information
and also does not execute relay selection algorithms. In ICC
with the benefit of Request-To-Send/Clear-To-Send(RTS/CTS) frames in MAC layer
node can obtain the MAC address of the node two-hops away. And node can receive the signal sent by the node two-hops away via adding the next two node MAC address in the data frame
then combine the cached data with the data forwarded by the upstream to obtain diversity gain.
