A Multi-Channel Energy-Efficient 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.
