摘要
CSMA/CA机制是一种应用广泛的无线网络MAC层接入方式,对其攻击手段的研究很多,但是对在攻击下CSMA/CA机制的网络性能分析研究不多。论文建立了一个简化版离散马尔科夫模型,对随机干扰、反应式干扰和智能干扰三种手段进行定量比较,得出干扰效果高低。
The CSMA /CA mechanism is a kind of access way and widely used in MAC layer of wireless network .There are a lot of attacking means for CSMA /CA mechanism ,but a less study for the performance analysis of the throughput of CSMA /CA mechanism under jamming .In this paper ,a discrete-time Markov chain analysis is used to derive formulae for the saturation throughput of memory less ,reactive and intelligent jamming .Then three mathematical saturation throughput are compared ,and the result is obtained.
