摘要 为了优化802.15.4 MAC协议性能,提出了一种基于退避时提前休眠的时隙CSMA/CA机制,建立了该协议的Markov链模型,并对模型进行了数学推导。然后基于该模型对信道吞吐量和节点功耗进行数值分析。理论分析和仿真结果表明,该模型较好的描述时隙CSMA/CA机制,协议性能得到有效改善。 To optimize the performance of IEEE 802.15.4 MAC,a mechanism that advancing sleep in back off stage for slotted CSMA/CA algorithm was proposed,and we established a Markov chain model for it.Then,mathematical derivation for the model was carried out.Furthermore,the numerical analysis based on the model of the channel throughput and node power consumption was carried out.Finally,it is showed by the theoretical analysis and simulation results that our model describe the slotted CSMA/CA mechanism well,and the performance of protocol is improved effective.
