摘要
分析节点位置均匀分布下发送节点与目的节点间的多跳传输概率分布特性;在Gupta信噪比干扰模型下,推导多跳网络容量上下界的闭合表达式,并对网络容量进行数值仿真.得到如下结论:网络中信息多跳传输的概率高于单跳传输的概率;多跳网络容量随着节点数量增加呈现先增后减的趋势;网络的多跳特性有利于提高网络容量.
This paper analyzed the connectivity of the network to form the hops-distribution formula between the source node and the destination node;then developed the expressions of the upper bound and lower bound of the multi-hop capacity based on the Gupta models. The numerical simulation shows： multi hop network capacity with the node number showed a trend of first increasing and then decreasing;and when the number of nodes increasing, single hop network capacity is higher than that of multi hop network capacity.
