无线网络中的多跳协作机制
New multi-hop cooperation mechanism for wireless networks
摘要
Abstract
The existing cooperation mechanism for wireless networks excessively depends on the channel state information. However, it is difficult to obtain the channel state information in practice bacause wireless channel state instantaneously changes. This paper proposed a new multi-hop cooperation mechanism( MCM) for wireless networks, which did not depend on the channel state information. MCM made use of inherently broadcast characteristics of wireless channel, so that enabled the intermediate nodes to cache and combined signals that were sent by the preceding nodes in a relay chain, and forwarded the recovered signals. And it employed theoretical analysis and simulation analysis to prove the feasibility and effectiveness of the proposed scheme. The results show that the MCM can improve the packet delivery ratio and the average end-to-end throughput compared to the multi-hop non-cooperation mechanism ( MNM).关键词
