Survey of routing base congestion control techniques under MANET

Mobile ad-hoc network is dynamic nature because each node moves freely in the network. In MANET we can't predict node motion and traffic load of each node, so number of nodes are ideal and number of node are vary loaded that leads the problem of congestion onto the network, here we design a survey paper related various congestion control under the MANET that work provide the congestion free as well as congestion avoidance techniques from network. In this survey we identify multipath routing and load aware technique both are provide more reliable as well as load aware of each node so minimize the data drop but all given approach are use routing base congestion control, through this survey we identify that congestion control through dynamic queue management technique, here we given about problem statement about dynamic queue base approach for congestion control and simulation parameter. In further we design proposed work and proposed algorithm and simulate through all network parameter base for performance evaluation.
