Development of efficient medium access control (MAC) protocols is a fundamental research issue in high-speed wireless local area networks (LANs). In this paper, we focus on the performance improvement both of MAC layer and transport layer by using a novel medium access control protocol in high-speed wireless LANs which use carrier sense multiple access/collision avoidance(CSMA/CA). We propose an efficient distributed contention-based MAC protocol, namely, the Fast Collision Resolution (FCR)

The performance of the FCR algorithm is compared with that of the IEEE 802.11 MAC algorithm via extensive simulation studies both in MAC layer and transport layer. The results show that the FCR algorithm achieves a significantly higher efficiency than the IEEE 802.11 MAC algorithm and is well suited for transport layer protocols such as transmission control protocol (TCP) and user datagram protocol (UDP).
