Impromvent Method of MAC Protocol Based on Adhoc Network Traffic Characteristic
In allusion to the self-similarity and burst characters of adhoc traffic and based on simulated input produced by multiple superposition of ON/OFF sources, a back-off algorithm about MAC protocol is raised which is suitable for adhoc burst traffic.Through rational analysis of burst status of each source,this algorithm introduced an appropriate competence coefficient, so that channel accessing of nodes can be rationally assigned in accordance to current network traffic status. Experiments executed on OPNET obtained each graph of network performance through analogue simulation under different number of terminals and different burst degree of traffic flow. The results showed the improved protocol have better performance in time delay and throughputs.
