基于同道干扰统计模型的无线自组织网络性能分析

Performance Analysis of Wireless Ad Hoc Network Based on Co-channel Interference Statistical Model

基于无线自组织网络中节点的分布特征,结合对同道干扰的定量分析结果,给出了一种适用于无线自组织网络的同道干扰统计模型。分析了无线自组织网络中同道干扰的统计特性,并基于建立的同道干扰模型研究了无线自组织网络的系统性能。结果表明,同道干扰对无线自组织网络的系统性能有严重影响,需建立合理的干扰模型才能更准确地评估自组织网络的系统性能。

A statistical model of co - channel interference（CCI） for wireless Ad Hoc network is established based on the distribution of the limited communication nodes. According to the presented CCI model, the statistical characteristics of CCI are analysed, and the performance of wireless Ad Hoc network is evaluated with CCI. Sim- ulation results indicate that the co- channel interference has an important effect on the Ad Hoc network, and it is necessary to explore the reasonable CCI model to evaluate the performance of Ad Hoc network.
