Mobile Ad Hoc networks (MANETs) are susceptible to having their effective operation compromised by a variety of security attacks. Nodes may misbehave either because they are malicious and deliberately wish to disrupt the network, or because they are selfish and wish to conserve their own limited resources such as power, or for other reasons. In this paper,(More)
—Wireless ad hoc networks provide the communications platform for new technologies and applications, such as vehicular ad hoc networks or wireless mesh networks. However, their multihop wireless nature makes them inherently unreliable and vulnerable, since their overall performance depends on the cooperative packet forwarding behavior of each individual(More)
Devices in a Mobile Ad Hoc network (MANET) may misbehave by dropping packets that are forwarded in the network, for example because they are malicious and deliberately intend to disrupt the network, or because they are selfish and wish to conserve their own limited resources such as power. In this paper, we present a mechanism that enables the detection of(More)
