在WSN提出一种非均匀多簇协作虚拟MIMO策略。以节点剩余能量、协作节点间距和节点至目的节点间距为参考依据，结合梯度搜索算法选取协作节点，以构建非均匀多簇。簇内节点通过空间分集方式协作通信，簇间通过空间复用方式并行传输，力求分集增益最大化。分析和仿真研究表明：该非均匀多簇协作策略在系统能耗和信道容量方面均有理想性能。

This paper presents a non-uniform multiple clusters strategy of virtual MIMO on WSN. It is based on node residual energy, the distance between collaborative nodes and node to the destination of node spacing,and then it selects collaboration node to construct a non-uniform Multiple Clusters and combined with the gradient search algorithm. In order to maximize diversity gain, the intra-cluster nodes communicate through space diversity and the adjacent clusters parallel transported by spatial multiplexing method. The analysis and simulation results show that:the system energy consumption and channel capacity give ide-al performance by using non-uniform multi-cluster collaboration strategy.
