Abstract: Aiming at the problems that existing UPP-LTE network congestion control algorithm can not adapt to the distributed network topology and the complex network environment and its efficiency is low,and cost is big,this paper analyzed LTE network wireless channel quality on the AODV protocol performance. Based on the path loss threshold cooperative mode AODV routing mechanism, this paper put forward a based on the ctueue length and the number of hops congestion control strategy. LI'E network link level and system level simulation experiment proves performance of the modified congestion control mechanism in wireless I'CP based on cooperative routing protocol. Mathematical analy- sis and simulation results show that compared with the traditional TCP congestion control mechanism,the cooperative congestion control mechanism has better performance.
Key words: Long term evolution(LTE) , Cooperative routing protocol, AODV , Management of congestion control
