Novel Probability-Based Access Control Protocol for Wireless LAN
Overview This paper proposes a novel probability-based access control protocol for wireless LAN, which outperforms the traditional CSMA (Carrier Sense Multiple Access) protocol for WLAN on delay and throughput according to the theory and simulation of this paper. Consider a system with n active stations accessing a multi-access channel. The random access protocol for controlling this channel is traditional p-persistent CSMA protocol. The p-persistent protocol considers three kinds of traffics: high, medium and low priorities. Voice (best-effort) service has the high (low) priority, and video service has the medium priority. For video and best-effort traffics, the four way handshake (RTS-CTS-DATA-ACK) is adopted. The basic access mechanism (DATA-ACK) is used for voice traffic, because the length of voice packet is much smaller.
