摘要
在基于协作通信的自组织网络中,需要对无线通信资源进行优化控制与合理协调,以提高对这些资源的使用效率,进而达到提高网络性能的目的;针对多信息流网络环境,以分布式最佳中继选择、基于节点状态的协作传输自适应以及跨层协作路由三大资源优化策略作为研究内容,对当前存在的研究成果进行了详尽的综述,并指出未来需要研究的内容以及需要解决的关键问题。
In cooperative ad hoc networks, it is necessary to optimize and distribute the wireless communication resource for improving the resource use efficiency and network performance. As for the multi-flow network scenario,this paper takes the resource optimization strategies as research contents such as distributed optimal relay selection,cooperative transmission self-adaption based on node status and cross-layer cooperative routing. Furthermore,the detailed review on present research results is conducted,and the future research contents and open key problems are pointed out.
