Backoff algorithm based on frame transmission efficiency in Ad hoc network

In order to alleviate the MAC layer congestion in Ad hoc network, and improve transmission performance, first, put forward an optimization computation model of the frame transmission efficiency, and then researched back-off algorithm. The simulation results indicate that the optimized frame transmission model can reflect the degree of congestion of Ad hoc network accurately, and the segmented back-off algorithm makes the average throughput of Ad hoc network increases by 30% on the basis of IEEE802.11 standard wireless protocols, and the average delay decreases by 41%, it is suitable for the wireless network transmission with higher real-time requirements.
