摘要
本文阐释了完全连通网络、平均路径长度和簇的概念;基于图论用矩阵表示网络拓扑,提出了一种计算簇的数目的新算法,并探讨了三种无线网络,其分别采用MIMO MRC,MIMO MRT和SISO技术连接;通过仿真显示运用MIMO方式通信能增强网络鲁棒性和降低平均能量消耗.
This paper presents the concepts of completely connected network, mean path length and cluster for analyzing the performance of wireless multihop network, where matrix is used to express topology of network and use a new algorithm to compute the number of cluster in the network. This paper discusses three types of multihop networks employing MIMO with maximum ratio combining （MRC）, and MIMO with maximum ratio transmission （MRT） and SISO as link model respectively, and gets that using MIMO link model can increase robust, decrease mean path length by simulation.
