【摘要】 无线射频识别技术中多阅读器环境下的信息传输是一个复杂的问题,该文针对这个问题,提出了多阅读器防碰撞的自适应分布式功率控制算法。该算法通过自适应的调整阅读器的发射功率来减小阅读器间的干扰,以使全部阅读器达到最佳的阅读范围。仿真实验中采用给定最小距离的多阅读器随机分布网络拓扑结构。仿真结果表明,RFID自适应分布式算法能有效地解决多阅读器信息碰撞,提高阅读器的读写距离。更多还原

【Abstract】 It is a complex problem on information transmission in dense reader network.A novel reader anticollision algorithm called distributed adaptive power control was proposed.The algorithm changed the reader transmitter power to adjust interference between readers,so that all readers achieved the best read range.In the simulation,it used a random distribution network topology.Simulation results show that the distributed adaptive power control algorithm can effectively solve reader collision in dense reader network and enhance the scope of readers to read and write.更多还原
