Abstract:

摘要: 针对当前无线局域网中信道切换时延问题,设计了一种新的快速信道切换方案FCH-USRP(fast channel handoff with USRP)。通过使用USRP(universal software radio peripheral)设备对所处无线环境进行信道扫描,以提供及时准确的无线信道信息,从而减少用户的信道切换时延。实验结果表明该方案能够有效减少信道切换时延,并在较短时间内恢复中断的数据传输。
Abstract: In order to mitigate the latency for channel handoff in wireless LAN, a novel channel handoff scheme named FCH-USRP is proposed. The FCH-USRP was based on the USRP equipped to provide timely and accurate wireless channel information for channel scan in wireless environment, thereby reducing the users channel switching delay. The experimental results show that the proposed scheme can effectively mitigate the delay of channel handoff and recover the interrupt data transmission in short time
