Topic
Jamming in Wireless Sensor Networks: Some Research Perspectives
Abstract
Jamming is an important class of attacks that can severely affect the successful functioning of any wireless network. The consequence of jamming in sensor networks is particularly serious due to their resource constraints and challenged environments of operation. The Fundamental reason for such vulnerability to attacks is the open and shared nature of communication medium of wireless networks. Depending on the attacker¹s objective, the attack is termed as jamming or misbehavior. If the attacker directly manipulates the protocol parameters to obtain performance benefits for itself, the attack is termed as misbehavior. The attack is referred to as jamming, if the attacker exploits protocol semantics by disrupting network communication intentionally. Sensor networks are subject to four kinds of jamming attacks constant, random, deceptive, and reactive jamming. Detection of jamming and its discrimination from other types of radio-link deteriorations, especially as applicable to wireless sensor networks, is a challenging problem; and as such, only few solutions exist. The speaker will talk about the problem of jamming in wireless sensor networks, with focus on military applications. He will then specifically talk about some of his works done with his colleagues and students in regard to jamming attack detection and jammed area mapping in wireless sensor networks.
