A Survey on Preventing Jamming Attacks in Wireless Communication

Communication in wireless network is possible with an air medium. Due to the high security threats in this system, the network may face various difficulties. One of the major threat is jamming attack which comes under Denial Of Service (DOS) attack. Jamming attack is common among many exploits that compromises the wireless environment. The work of authorized users is by denying service to as legitimate traffic is jammed by the overwhelming frequencies of illegitimate traffic.In order to mitigate the impact of jamming, three techniques are being used: (a) how to thwart jamming in control channel (b) An Anti-jamming broadcast communication using Uncoordinated Spread Spectrum (USS) technique (c) Mitigating jamming impact in timing channel. We analyse these methods for reducing jamming inside a network.
