A specification based intrusion detection mechanism for the LEACH protocol

Abstract:

With the improvement of the wireless communication and embedded technology, the application of wireless sensor network has increased to various fields. However, such type of network embeds more vulnerabilities than others because of its resource constrained characteristic. To counteract such problem, traditional security mechanisms such as cryptography and authentication have been used. However, those are not enough to solve all security issues that may happen in the wireless sensor network, especially those attacks executed by a compromised node. This fact creates the need for a complementary security mechanism. This paper proposes a specification-based intrusion detection mechanism for the wireless sensor network, specifically for the popular cluster based Low Energy Adaptive Clustering Hierarchy (LEACH) protocol. It identifies the possible attacks in different phases of such protocol, develop the intrusion detection mechanism and execute simulations to analyze the efficiency of the proposed solution. This paper has also shown how the proposed mechanism offers a high intrusion detection rate while maintaining a low traffic overhead. © 2012 Asian Network for Scientific Information.
