Research of the Dynamic MAC Protocol of Wireless LAN Distributed Coordination Function(DFC) 无线局域网分布式协调功能(DFC)动态MAC协议分析
After the whole functional architecture is introduced, we study the distributed coordination function ( DCF ) and the point coordination function ( PCF ). 分析了MAC层的总体功能结构,介绍了其中的分布协调功能(DCF)和点协调功能(PCF)功能。
Aimed at two primary channel allocation mechanisms of MAC layer in IEEE 802.11 WLAN, Distributed Coordination Function(DFC) ( DCF ) and Point Coordination Function ( PCF ), a performance analysis and comparisons have been done. 对IEEE802.11MAC层两种主要的信道分配机制&分布式协调功能(DFC)(DCF)和点协调功能(PCF)进行了性能的分析和比较。
IEEE 802.11 distributed coordination function ( DCF ) only supports transmission in the forward direction from senders to receivers. IEEE802.11分布式协调功能(DFC)(DCF)只支持前向数据传输,即数据帧只能由发送方传送到接收方。
Analysis on the performance of the enhanced distributed coordination function ( EDCF ) in IEEE 802.11e IEEE802.11e无线网络协议标准中增强分布式协调功能(DFC)(EDCF)性能分析
