Abstract

Abstract: The polling protocol is a classic Media Access Control(MAC) layer Time Division Multiple Access(TDMA) time slot allocation protocol,which has the characteristics of collision-free data communication and low power consumption,but it cannot guarantee communication reliability and realize differential services.Therefore,a TDMA time slot allocation protocol with dynamic retransmission and differential service mechanisms is studied.The frame structure is redesigned,and the static time slot allocation is completed according to the information of the terminal node data packet.When the data transmission fails,the retransmission time slot is used to improve the communication reliability,and the differential service is realized by the shadow time slot.Experimental results on the wireless meter reading system show that compared with the classic polling protocol,the packet loss rate of the protocol is reduced by 3%.

摘要： 轮询协议是一种经典的介质访问控制（MAC）层时分多址（TDMA）时隙分配协议，具有无冲突数据通信且功耗低的特点，但无法保证通信可靠性及实现有区别服务。为此，研究一种具有动态重传和差异服务机制的TDMA时隙分配协议。重新设计帧结构，根据终端节点数据包信息完成静态时隙分配，在数据传输失败时，利用重传时隙提高通信可靠性，通过影子时隙实现有区别服务。在无线抄表系统上的实验结果表明，与经典轮询协议相比，该协议的丢包率降低了3%。
