| 摘 要： | 提出了概率函数检测随机多址接入无线传感器网络MAC(FPRM)协议.在发送分组的时间1+a中,采用p(x)函数检测的控制策略,增加握手的ACK信号,提高无线传感器网络的传输效率.通过平均周期法的理论分析和选取不同的p(x)函数值的仿真实验,获得的结果相吻合.分析结果表明,FPRM协议能有效地分配无线传感器网络的信道资源,提高系统的传输质量.

| Abstract: | A new random multi-access protocol for wireless sensor networks(WSNs) was presented.This protocol used the function p(x)-detection control strategy in the packet transmit 1+a and added acknowledge character(ACK) to the system,it can improve the transmission efficiency of WSNs.Compared the theoretical analysis method of average period with the selection of different p(x) function value simulation experiments,they were consistent.The results showed that the protocol enabled the WSNs' channel resources effecti... |
