Abstract An extension MAC Protocol based on 802.11e is proposed for better supporting Class of Service in data link layer of Ad hoc. By using multiple reserving channel method, the superiority of the higher priority flows in medium contention is enhanced. By using the diffusion of innovation theory, the low priority flows lower their sending probability to protect the higher priority services, and information flooding is avoided in the whole ad hoc network. Analysis and simulation results show that the extension protocol can improve the success of the high priority data’s throughputs and remarkably reduce end-to-end delay and jitter.
