摘　　要：针对煤矿巷道的特殊地理环境,分析LEACH协议和多跳虚拟MIMO为何会形成"热区"问题,提出一种多跳非均匀分簇(MU-V-MIMO)算法,介绍基于此算法的模型传输过程及能耗分析;通过MATLAB仿真,运用MU-V-MIMO算法的虚拟MIMO在网络总能耗和传感器网络生命周期等性能优于LEACH协议,更适合应用于煤矿巷道。Aiming at the special geographical environment in coal mine tunnel, this paper analyzes the problem of why LEACH protocol and multi -hop virtual MIMO will form ＂hot zone＂. Based on the problem, this paper proposes the MU -V -MIMO algorithm, and introduces the transmission model process and energy consumption analysis with the algorithm. Through the Matlab simulation, the vi- tual MIMO used of MU - V - MIMO algorithm is better than LEACH protocol in total network energy consumption, sensor networks life cycle and other performance, which is more applicable in coal mine tunnel.
