基于分布式协作的802.11MAC层类时分复用协议
Pseudo-TDMA Protocol of 802.11 MAC Level Based Distribution Cooperation
802.11作为无线局域网协议为中短距离无线通信量身定制，广泛使用的WiFi主要支持EDCA，该MAC控制模式在高密度用户接入的时候会加剧碰撞，性能下降严重，本文提出了一种基于分布式协作的类时分复用MAC层协议，在高密度用户条件下能有效改善网络性能，提高吞吐量和数据包的有效交付率，在传输短数据帧时，该协议性能比HCCA更好。
he 802.11 protocol is specially userd for short and middle distance communication in wireless LAN. The WiFi wild used now mainly support EDCA, which is an option of 802.11 MAC mechanism. The capacity of network performs bad in EDCA for the collsion happens too much when the user density is high. We propose a protocol for this specially application scene, simulation shows that the protocol can effectively improve the throughput and data packets’ transformation, and performs better than HCCA mechanism when send short data packets.
