摘要
在融合无线传感器的RFID系统中,能量是一个非常关键的资源。通过基于轻量级MAC协议的自适应功率控制算法,采用自适应机制和自适应功率控制机制实现了节能的目标,并因此延长了网络的生存时间。提出了基于码分多址的防碰撞算法,通过有效的防碰撞方法,缩短了传输时间,明显提高了系统的能量利用效率。
In RFID system integrated with wireless sensors, energy is a critical resource. Through the adaptive power control algorithm based on lightweight MAC protocol and adopting the adaptive mechanism and the adaptive power control mechanism, the energy saving goal is achieved, and therefore the survival time of network is extended. An anti-collision algorithm based on CDMA(code division multiple access)is put forward to shorten the the transmission time and improve the energy efficiency of the system obviously.
