摘要
指出了现有的基于不定长时隙的DCF协议马尔可夫链模型的局限性,并在详细分析多跳adhoc网络环境中DCF协议建模的难点问题基础上,提出了一种基于定长时隙的多跳ad hoc网络DCF协议马尔可夫链模型.通过模型的求解,得到了反映多跳ad hoc网络饱和吞吐量性能的相关性能指标的理论值,并结合GloMoSim网络仿真环境中的仿真实验,证明了模型的有效性.
This paper points out the limitations of the existing Markov model of DCF protocol based on tin-fixed slot in ad hoc networks, and analyzes the difficulty of the modeling of DCF protocol in multi-hop ad hoc networks in detail. On the basis of this, this paper proposes a Markov model of DCF protocol based on fixed slot in multi-hop ad hoc networks. By solving this model, the theoretic value which reflects the saturated throughput performance of multi-hop ad hoc networks is obtained. The effectiveness of this model is demonstrated by the simulations in GloMoSim environment.
