| 摘 要： | 提出了一种新的随机多址接入无线传感器网络的MAC控制协议,在发送分组的时间1+a中,采用P概率检测与1-坚持的联合控制策略,并对多通道的随机多址接入无线传感器网络进行了分析,理论分析了系统的吞吐量和多通道中不同业务的吞吐量,以及信息分组的发送时延等参数,理论分析与仿真实验结果相一致.还结合无线传感器网络的能量有效性,通过对概率P值的选取,控制忙周期侦听信道的节点数和空闲期的休眠站点数,采用休眠技术实现了系统的节能效果.通过对2种无线传感器网络控制协议的能量有效性分析,证明了改进的控制协议其节点具有更长的生命周期,更适合作为无线传感器网络的MAC控制协议.

| Abstract: | A novel random multi-access MAC protocol for WSN using the multi-channel and the probability detection and 1-persistent access policy in the packet transmit(1+a) was proposed.The throughputs of the PDPMRM protocol and the multi-traffic were obtained.Simulations agree with the theoretical analysis.Also,the energy efficiency was analyzed for WSN by choice of probability p to control the waking nodes in busy period and the sleeping nodes in idle period.The sleeping technique realized the purpose of saving ener... |
