摘要：Routing protocols for mobile ad hoc networks (MANETs) havebeen explored extensively in last few years. Much of this work istargeted at finding a feasible route from a source to a destinationwithout considering current network traffic or applicationrequirements. Routing may let a congestion happen which isdetected by congestion control, but dealing with congestion inreactive manner results in longer delay, and unnecessary packetloss and requires significant overhead if a new route is needed.Routing should not be aware of, but also be adaptive to, networkcongestion. Adaptation to the congestion helps to increase both theeffectiveness and efficiency of routing. These problems are solvedby the congestion-aware routing protocols in certain degree. Theseprotocols which are adaptive to congestion status of mobile ad-hocnetwork can greatly improve the network performance. In thispaper, we present the survey of congestion adaptive routingprotocols for mobile ad-hoc network. Finally, the future directionof congestion-aware routing protocols is described
