Abstract:
This paper proposes a Markov chain model for performance analysis and evaluation of S-MAC protocol. The model uses the moment generating function and signal flow graph to analyze MAC access delay of S-MAC protocol. M/G/1/K queuing model is applied for performance analysis of the protocol in non-saturation condition. Mathematical analysis and simulation experimental results demonstrate the model can describe the access way of S-MAC protocol well.

摘要: 提出一种二维Markov链模型用于S-MAC协议的性能分析与评价。该模型利用信号流图和母函数的方法分析S-MAC协议的介质访问控制(MAC)服务时延,结合M/G/1/K排队模型分析S-MAC协议在非饱和负载下的性能。仿真实验和数值分析结果证明该模型可以较好地描述S-MAC的接入方式。
