The IEEE 802.11 has been shown to be quite inefficient in multihop networks. Besides the problems of hidden terminal and exposed terminal, there is also unreachability problem, which may result in link/routing failures and unfairness among multiple traffic flows. In this paper, a novel medium access control (MAC) protocol, called eMAC, is proposed. Under the proposed scheme, stations maintain double...
Many performance evaluations for the IEEE 802.11 Distributed Coordination Function (DCF) have been previously reported in the literature; most studies are based on saturation analysis, and a few models under a finite-load condition adopt an M/G/1 queuing system. However, using M/G/1 queuing only considers the first moment of the frame service time to derive the probability of the transmission queue...
