This paper propose a Dynamic Exponential Smoothing Model-Based Load Balancing Protocol for Traffic Prediction in Ad Hoc Networks.DES-LBPTP.By predicting the traffic load with dynamic exponential smoothing model according to the number of data packets in the interface queue of MAC layer,the nodes′ load state in the future can be determined earlier.Then the route-discovery mechanism prevent the forthcoming congestion,and the transfer reliability can be improved.In addition,the selectively transfer of RREQ on the basis of the load status and the delay response of destination node also improve the network performance to some extent.Simulation results proved that,in comparison with the traditional protocol,DES-LBPTP protocol can reduce the end-to-end delay by approximately 50% and the normalized routing overhead by 28%,while raising the delivery ratio by 10.4%.
