| 摘 要： | 为了解决射频识别(RFID)网络中的读写器冲突,提出了一种异步的基于预约的多信道读写器冲突避免媒质接入控制(MAC)协议。读写器根据控制信道监测到的邻读写器当前信道使用情况,选择一个空闲通信信道并向邻读写器广播,从而实现读写器无冲突地与标签通信。该协议避免了多个相邻读写器同时与标签通信,解决了读写器?标签干扰,并采用多信道通信和频率空分复用机制避免了读写器间频率干扰的发生。

| Abstract: | In order to solve the reader collision problem in radio-frequency identification(RFID) networks,a collision avoidance asynchronous multi-channel medium access control(MAC) protocol is proposed.Each reader monitors the control channel,thus obtains the occupied channels and communication states of neighbor readers.Then,an unused channel is adaptively selected as the communication channel to transmit request to send(RTS) to its neighbor readers to broadcast this choice.Thus the non-collision communication is r... |
