Harnessing delay tolerance to increase delivery ratios in mobile ad hoc networks with misbehaving nodes

Delay tolerant applications allow time to be used as an additional degree of freedom for security mechanisms in mobile ad hoc networks. By introducing artificial delays for the communication of delay tolerant applications, we optimize the point in time for starting or continuing a transmission. We develop mechanisms to exploit the knowledge on the proximity of the sender, the receiver, and intermediate, relaying nodes to misbehaving nodes detected. We propose different strategies for delayed transmission and provide a performance analysis based on a series of simulation studies. Our results show that we reduce the effects of misbehavior by keeping away data from misbehaving nodes.
