Security Threats and Jamming Attacks of Multi Channel Wireless Sensor Networks
Built upon a shared wireless medium, wireless sensor network is particularly vulnerable to jamming attacks. These attacks can easily be accomplished by an adversary by either bypassing MAC-layer protocols or emitting a radio signal targeted at jamming a particular channel. This paper considers a scenario where a sophisticated jammer jams an area in a multichannel wireless sensor network. The jammer controls the probability of jamming and transmission range to cause maximal damage to the network in terms of corrupted communication links.
