Detection of Node Capture Attacks in Wireless Sensor Networks

Abstract

Wireless Sensor Network is a gathering of sensors with incomplete resources that collaborate in order to achieve a shared goal. It is susceptible to node capture attacks because sensor nodes are deployed in unattended manner. Once opponent imprisonments sensor nodes, he can compromise that node and presentation various types of occurrences with those compromised nodes. The antagonist takes the secret keying possessions from a compromised node, generates a large number of attacker-controlled imitations that share the cooperated node’s keying materials and ID, and then feasts these replicas throughout the system. Therefore, captivity node attacks are perilous and should be noticed that node to reduce the harm. Several replica node detection schemes have been proposed against these attacks in static instrument networks. These methods are worked only in static sensor network and hence do not work in mobile sensor networks. In this work, propose a fast and effective mobile replication node discovery scheme using event-based attack decomposition. It shows logically and through imitation experimentations that our scheme detects mobile imitations in an efficient and robust method at the cost of judicious expenses.
