摘要

研究了在富多径传播环境下运行的自组织无线网络。假设节点间通信链路采用多单元天线和MIMO空间复用收发策略。分析了存在径间干扰时的信噪比(SINR)。当以对等链路的服务质量(QoS)为性能标准时，传输节点之间的协作是为了避免通过并发路径的流冲突。讨论了一种改进的浇水算法(RWPA)，该算法可以根据QoS性能标准在传输天线之间重新分配功率。仿真部分采用两对节点间通信链路对场景进行分析。

Sustaining the lower bound of QoS in MIMO ad-hoc network with concurrent virtual streams

The ad hoc wireless network that operates in the rich multipath propagation environment is considered. It is supposed that the node to node communication links are performed with multi-element antennae and MIMO spatial multiplexing transmitting-receiving strategy in use. The signal to interference plus noise ratio (SINR) in the presence of interpath interference is analyzed. The cooperation among transmitted nodes is used to avoid the stream collision through the concurrent paths when the performance criteria is the quality of service (QoS) of peer to peer links. The revised water pouring algorithm (RWPA) that helps to redistribute the power among the transmitted antennae according to QoS performance criteria is discussed. The simulation part analyzes scenario with two pairs of node to node communication links.
