| 摘 要： | 为了更进一步减少信道冲突和网络能耗,提出一种基于令牌的链式无线传感器网络MAC协议.协议自定义信标帧和数据帧,在传感器节点完成时间同步后,以信标帧中的令牌为控制信息对相邻两个传感器节点进行收发控制,实现数据从链尾节点到链头节点的顺序上传.研究表明,该协议不仅能够满足系统的稳定性要求而且能够有效降低功耗.

| Abstract: | In order to reduce the channel conflict and energy consumption of the network, design a chain-type wireless sensor network MAC protocol based on token. The protocol defines the beacon frame and data frame, after the sensor nodes finishing time synchronization, it takes the token in the beacon frame to control the two adjacent sensor nodes to transmit or receive data, finally upload the information from the end to the head . Researches show that the new protocol can not only meets requirement of the system＇s stability but also reduce the energy consumption. |
