| 摘 要： | 将无线射频识别(RFID)技术与无线传感器网络相融合，设计具有RFID读取功能的传感器节点。针对基于RFID的无线传感器网络，提出基于簇族结构的节能MAC协议——CSMAC协议。该协议具有节能和广播导向等特征，采用冲突减少机制来提高信道利用率，同时采用减少发送时间、减少监听时间、减少开关转换时间等功率优化机制，以提高网络能量效率。仿真试验表明，与传统MAC协议相比，CSMAC协议更能提高信道利用率和能量效率。

| Abstract: | 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. |
