BDCF——支持双向传输的无线局域网协议
BDCF——a MAC protocol to support bi-directional transmission in a wireless LAN
摘要
Abstract
In order to fully utilize the limited frequency and bandwidth resources in 802.11 wireless local area networks (WLAN), a novel media access control (MAC) protocol which supports bi-directional transmission is proposed. The protocol makes two packets respectively from the senderand the receiver transmit together through one frame exchange sequence to reduce the network overhead and save the bandwidth resources. The analytical model and the simulation results show that,compared with other MAC protocols, the proposed protocol can significantly improve the average throughput of bi-directional flows, while maintaining the backward compatibility with the legacy 802.11 distributed coordination function (DCF) protocol.关键词
