Alibi framework for identifying insider jamming attacks in half-duplex wireless local area networks
… networks, unfortunately, are vulnerable to radio jamming attacks (in short, ``jamming attacks'') due to the open and shared nature of wireless medium. In a jamming attack, an attacker injects a high level of noise into the wireless system which significantly reduces the signal-to-noise ratio …

Cluster based jamming and countermeasures for wireless sensor network MAC protocols
… duty cycle makes a node vulnerable to periodic jamming attacks. This vulnerability limits the use of use of a WSN in applications requiring high levels of security. We present a new WSN MAC protocol, RSMAC (Random Sleep MAC) that is designed to provide resistance to periodic jamming attacks …
