摘要: 分析了捕获效应下节点随机分布的、无中心控制的分布式无线ad hoc网络的饱和吞吐量,得出了节点均匀分布的ad hoc网络捕获概率的表达式,以及在一定捕获概率下吞吐量的表达式,并使用网络仿真进行了验证。

Abstract: The influence of capture effect on saturation throughput of distributed wireless ad hoc network is investigated. The capture probabilit y of ad hoc networks whose nodes are uniformly distributed is obtained. With certain capture probability, the saturation throughput of 802.11 DCF is also derived.

Key words: Wireless ad hoc networks, Capture effect, Saturation throughput
