Wireless Sensor Networks Hybrid MAC Protocol for Overhead Transmission Line Monitoring
一种面向输电线路监测的WSN混合式MAC协议

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.
