混合传播方式Ad hoc无线网络的容量研究

摘要

A new capacity analysis method for the Ad hoc network with heterogeneous traffic patterns is presented in this paper: deciding the capacity-dominant traffic pattem by comparing the capacity scale of each traffic pattern in the network. Based on this method, the proportion of unicast and multicast capacity is used to study the capacity-dominant traffic pattems and network capacity of a unicast-multicast heterogeneous network applying multihop transmission mechanisms, MIMO technology and hierarchical cooperation. Less-than-half multicast nodes would domiMte the whole network capacity.%提出一种混合传播方式Ad hoc网络容量研究的方法,通过比较各传播方式在其相应规模下的容量确定主导传播方式并得出网络总容量.并以单播和多播混合传播为例,研究在基于多跳、MIMO和层次化合作情况下的主导传播方式和网络总容量.当该混合网络中单播的结节过半时,由多播传播方式确定网络的总容量.
