Mitigation of jamming attacks in wireless networks

Wireless networks, intentional interference can be used as a launch pad for mounting Denial-of-Service in the network. Intentional interference (jamming) attacks can be performed by absorption of packets and discard them or drop the packets. Intrusion Detection System can be used to mitigate and prevent the jamming attack and the addition of cryptographic primitive used to preserve integrity of the packets. This paper proposes a mechanism for preventing jamming attacks on wireless networks-examine the detection efficiency of jamming attack and communication overhead of the wireless network using proactive and reactive protocols. RSA algorithm is used for providing data packets integrity information during wireless transmission. Through simulation and performance analysis, the implemented prevention mechanism and the integrity preservation provides higher packet delivery ratio in proactive routing protocol (OLSR) than reactive routing protocol (AODV).
