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。 |

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. |
