Wireless Network: Attacks and Countermeasures

Abstract Wireless Mesh Networks (WMNs) have emerging application because of its ad-hoc features, high internet bandwidth capability, and interoperable with various networks. However, all features of WMNs vulnerable due to their inadequate security services, and most of the existing techniques protect WMNs from single adversary node, but failed to protect colluding attacks. We proposed new Intrusion Detection (ID) technique, to protect the WMNs from wormhole attack (colluding attack) and following jellyfish and byzantine attacks. The proposed ID technique works based on different delays such as initial end-to-end packet delay, average end-to-end packet delay, and worst case end-to-end packet delay because wormhole attackers attract the network nodes by sending lower latency. Eventually, simulation results show that, our ID technique improves throughput of the network, when source and destination nodes detect and isolate (select new path which does not contain adversaries) the adver...

Whenever the legitimate nodes receive the originalsource request packets, they are dropped because legitimate nodes,would have already received packet from the attacker and treat the currently received packets asduplicate packets. Thus, adversary is included in active routeand disturbs the data forwarding phase. Rushing attack can be takenplace at...
