Wireless communication faces several security risks. An attacker can easily inject bogus packets, impersonating another sender. We refer to this attack as a spoofing attack. An attacker can also easily eavesdrop on communication record packets, and replay the (potentially altered) packets. In this paper, we are concerned of a particularly severe security attack that affects the ad hoc networks routing...
Ad hoc networks can be rapidly deployed and reconfigured. Hence, they are very appealing as they can be tailored to lots of applications. Due to their features they are vulnerable to attacks. A particularly severe security attack, called the wormhole attack, has been introduced in the context of ad-hoc networks. During the attack a malicious node captures packets from one location in the network,...
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 node. In this paper we present a role-based approach...
