摘　　要：在无线网络数学图论模型的基础上,提出了一个基于多跳邻接矩阵的无线Ad Hoc网络的路由选择协议(MRP)并和DSBR协议作了比较仿真分析,分析了信息传输的误比特率问题并提出了控制方案,以及分析了节点移动性对无线网络信干比(SINR)期望性能的影响并得出信干比期望性能随节点移动速度的增大而增大、随发射距离的增大而减小的结论。A multi-hop graph adjacent matrix based routing selective protocol（MRP） for wireless Ad Hoc networks was studied and compared with the DSBR protocol by simulating and analyzing. The Error Bit Ratio problem and its controllable scheme were presented and analyzed, additionally, the impact of node mobility on the expected capacity of SINR of the wireless networks was analyzed and resulted in the conclusions that the expected capacity of SINR would increase when the mobile node accelerated, and decrease when the transmission range extended.
