Detection of Diffusion in Attacks

A wireless sensor network is a group of specialized transducers with a communications infrastructure for monitoring and recording conditions at diverse locations [2]. Internal attackers (Insiders) that perform attacks have a distinct advantage over external attackers because they have authorized system access and also may be familiar with network architecture and system policies/procedures [3]. In addition, there may be less security against insider attacks because many organizations focus on protection from external attacks. This paper is on specific internal attack wormhole attack and a LOCALIZED FAULTY DETECTION ALGORITHM used to identify faulty nodes in sensor with the help of neighboring sensor and by using two predefined threshold values ϴ1, ϴ2 [4].
