Energy aware MAC technique for wireless sensor networks based on RFID
基于RFID的无线传感器网络节能MAC技术

By integrating RFID into a Wireless Sensor Network (WSN), the nodes of sensor that can read RFID tags were designed. Then, an energy-saving MAC protocol named CSMAC for WSN based on RFID was proposed based on cluster structure. This protocol with energy-saving and radio-oriented features raised the channel's efficiency of communication by decreasing the collisions. At the same time, it improved the energy efficiency of the network by reducing transmission time, listening monitoring time, and cutting down switching power conversion time. Simulation results show that, compared to the traditional MAC protocol, the proposed protocol can enhance channel utilization and energy efficiency.
