提出了一种低功耗的随机多址无线传感器MAC协议——时隙式非坚持与p概率检测多通道随机多址联合控制协议.算法通过划分系统的传输期,在不同的时段采用不同的控制策略和休眠机制,使系统获得较优的性能.通过对多通道多业务随机多址系统的理论建模分析,得出系统吞吐量、多业务吞吐量以及这种协议下传感器网络的能量效率的重要系统参数表达式.还通过计算机仿真实验与理论值进行对照,验证了理论的正确性,并发现其节点具有较长的生命周期.
This paper presented a kind of random persistent and Probability Detection joint control for Multi-channel Random Multi-access(NPDMRM).It divided transmission period of system into two parts in which different control strategies and sleeping mechanism were adopted,so the system could present excellent performance.This paper calculated the expression of important parameters like throughput of system,throughput of different business and the energy efficiency of WSN through analyzing the random multi-access system in the condition of multi-channel and multi-business theoretically.It then proved that the theoretical analysis was true through computer simulation experiment.We can get from the result that NPDMRM has long life cycle.
