Abstract

Abstract:

In order to solve the problem that the existing medium access control(MAC) layer protocols in wireless local area networks(WLAN) are less efficient, a fixed time and random extended implicit MAC Acknowledgment protocol is proposed on basis of extended implicit MAC acknowledgment (EIA). Since the proposed protocol brings in the leader and reduces the number of the multicast clear to send frames, the average channel holding time of transmitting data is reduced and the ratio of the real data transmission cost in entire multicast stage is increased. Simulations show that the proposed fixed time random extended implicit MAC acknwledgment protocol effectively improves the overall performance of multicast in WLAN and effectively increases the network goodput compared with EIA.

Key words: wireless local area networks, medium access control layer, reliable multicast control protocol, multicast control frames
