无线传感器网络多信道节能信道接入控制协议

在无线传感器网络MAC这一广阔的研究领域已经开展了很多研究工作,但迄今对能量节省并没有很好的解决方案,一般都以牺牲其他性能来降低能耗的.多信道节能MAC协议结合传感器网络对信道接入控制的要求,综合提高了网络性能,通过ns-2仿真,验证了本协议在能量节省、信道公平性以及网络吞吐量等方面的性能改善.

A Multi-Channel Energy-Eff icient MAC Protocol for Wireless Sensor Networks

Much research work has already been launched in wireless sensor network, which is a wide research field. But there has been no good solution to energy saving so far. Commonly energy saving is accomplished by sacrificing other performance of the network. Considering the request for medium access control of sensor network, a multi-channel energy-efficient MAC protocol is proposed, which improves the performance of the network synthetically. Simulation results show that there is dramatically improvement in energy efficient, network throughput and it can also achieve better fairness.
