Distributed Detection of Clone Attacks in Wireless Sensor Networks Using Detection Protocols

Abstract

A Wireless Sensor Network (WSN) is a collection of sensors with limited resources that collaborate in order to achieve a common goal. Sensor nodes operate in hostile environments such as battle fields and surveillance zones. Due to their operating nature, WSNs are often unattended, hence prone to several kinds of novel attacks. Sensor network attacks into three main categories: identity attacks, Routing Attacks and Network Intrusion. Identity attacks intend to steal the identities of legitimate nodes operating in the sensor network. The Identity attacks are Sybil attack and clone attack(node replication attack).A node replication attack is an attempt by the adversary to add one or more nodes to the network that use the same ID as another node in the network. This project only concentrating on an identity attack called replication attack where one or more nodes illegitimately claim an identity of legitimate node and replicated in whole WSN network.
