Reliable data transmission against packet dropping misbehavior in wireless ad hoc networks

Many routing protocols in MANET have been proposed to resist packet dropping attacks by removing suspicious node from route. However, when they cannot discovery who is an adversary, they cannot effectively deal with packet dropping attacks launch by the adversary. In other words, when there is anyone type of packet dropping attacks they cannot resist, the packet delivery rate will be influenced. In view of this, we propose a novel scheme to mitigate the influence of any kind of packet dropping attacks in MANET. Further, our scheme can cooperate with other protocols to acquire better packet delivery rate and to decrease overheads. The security analysis and simulation study in this paper verify the effectiveness and efficiency of our scheme.
