Comparison between Old and Advanced Scheme of Buffer Management in Packet Queuing For Controlling Congestion in MANET

Mobile Ad hoc Network (MANET) is a network with dynamic topology and mobile nodes. Due to the dynamic nature of network, there is no central control. Hence, nodes communicate with other nodes through intermediate nodes. The intermediate nodes are normal nodes in the same network and assume the responsibility of forwarding packets on the route from source to destination. Congestion control and securities are major tasks in MANET. Congestion control works very well in TCP over internet. But due to dynamic topology congestion control is a challenging task in mobile ad hoc network. Many approaches have been planned for congestion control in MANET. Congestion control technique is the procedure by which the network bandwidth is dispersed across multiple end to end connections. In this paper we are have done a comparison between “A Buffer Management Scheme in Packet Queue Management� and “A Advanced Buffer Management Scheme in Packet Queue Management� in MANET.
