摘要:

提出了一种新的自适应混合MAC协议TC2-MAC 该协议采用了基于二叉树结构的时隙块分配策略和基于时隙约束的CSMA/CA竞争接入方式,能够为不同传感器节点或不同类型业务的差异性QoS需求提供良好支持,并能够通过灵活的信息调度机制改善信道接入公平性,提高网络效率 理论分析和仿真结果表明:与传统基于 TDMA 机制的 MAC 协议相比,TC2-MAC 对网络业务流量及拓扑结构的变化均具有更好的自适应性

关键词: 无线传感器网络, TC2-MAC, 二叉树时隙块, QoS

Abstract:

A novel adaptive hybrid medium access control (MAC) protocol TC2-MAC has been proposed. The protocol used binary tree based time-slot-block (TSB) allocation strategy and time slot constrained carrier sense multiple access with collision avoidance (CSMA/CA) method to ensure heterogeneous sensor nodes or different types of traffic obtain personalized quality of service (QoS). In addition, it provided flexible information scheduling mechanism to improve fairness of channel access and enhance network efficiency enable. Results show that TC2-MAC has significant adaptabil-ity to the change of network traffic and network topology compared with traditional time division multiple access (TDMA) based MAC.

Key words: wireless sensor network, TC2-MAC, binary tree based time-slot-block (TSB), QoS
