A Study of Congestion Aware Adaptive Routing Protocols in MANET
Routing protocols for Mobile Ad hoc NETworks (MANETs) have been explored extensively in last few years. Much of this paper is targeted at finding a feasible route from a source to a destination without considering current network traffic or application requirements. Routing may let a congestion happen which is detected by congestion control, but dealing with congestion in reactive manner results in longer delay, and unnecessary packet loss and requires significant overhead if a new route is needed. Routing should not be aware of, but also be adaptive to, network congestion. Adaptation to the congestion helps to increase both the effectiveness and efficiency of routing.
