Abstract:

The medium access control(MAC)issue is discussed in mobile Ad Hoc networks(MANETs). Based on the IEEE 802. 11 MAC protocol, this paper proposes two schemes, the forward-packet-first(FPF)scheme based on the adaptive backoff contention window and multihop forward chain transmission by invitation(MFCTI)scheme. In the FPF scheme, the contention window is adjusted adaptively according to the traffic priority. Route information and the broadcast characteristic of radio are utilized in MFCTI scheme. The performance of these schemes is studied in multihop environments by simulations. The results show that the proposed schemes can improve the network throughput, reduce the end-to-end average delay, and mitigate local congestion effectively. Another attractive feature is that the schemes can be implemented with minor modifications to the IEEE 802. 11 MAC.
