A MAC protocol supporting multiple traffic over mobile Ad Hoc networks

In this paper, a multi-channel MAC protocol that supports multiple traffics will be presented. The dynamic channel selection scheme by receiver decision is implemented and the number of the data channel is independent of the network topology. An adaptive back off algorithm is employed to provide service differentiation for delay sensitive and best-effort traffic. The simulation results have shown that it can support multiple traffics and provide a certain QoS guarantee.
