摘要: 考虑到应用于输电线路监测系统中的无线传感器网络在拓扑结构、网络流量上都呈现出新的特点,提出了一 种混合式MAC协议,即在网络空闲时期使用X-MAC协议,在繁忙时期使用流水线式传输调度方法。根据节点的不 同角色,使用不同的X-MAC参数提高网络的响应实时性,采用流水线式的传输调度解决线状网络中的隐藏终端问 题。仿真结果表明,这种协议能够满足网络对实时性和能量有效性的要求。

Abstract: Considering the new feature of wireless sensor network applying to the overhead transmission line monitoring in topology and network traffic,a hybrid MAC protocol was proposed. The protocol adopts X-MAC during idle period and pipelined transmission during busy period. It uses different X-MAC parameters according to node's role to improve real-time performance and pipelined transmission to resolve the hidden terminal problem. Simulation results show that the protocol can meet the network's requirement of real-time and energy efficient.
Key words: Wireless sensor networks,Overhead transmission line monitoring,MAC protocol
