A distributed cooperation protocol for high density user adaption

IEEE802.11 wireless local area network (WLAN) series protocol is customized design for short and middle distance in wireless communication, whose medium access control (MAC) layer mostly supports distributed coordination function (DCF). However, DCF mode will lead to serious conflict when high density users are trying to access, thus the network performance degrades heavily. This paper proposes a distributed cooperation protocol called DCP for high density user adaption acting on MAC layer, which is similar to time-division multiple access (TDMA) protocol of MAC layer. Under the circumstance of high density user, our proposed protocol can effectively enhance the network performance, and improve the network throughput and the transformation of data packets.
