Detection of Mobile Replica Node Attacks in Mobile Sensor Networks Using Speed Measurement Testing
Journal Title: International Journal of Advanced Research in Computer Engineering & Technology(IJARCET) - Year 2012, Vol 1, Issue 10
Abstract
Wireless sensor networks contains large number of sensor nodes they are deployed in hostile environment so there is no security. An adversary may capture and compromise the sensor node and make replicas of them. The replica nodes are also called duplicate nodes. These replica node attacks are dangerous which leads to eaves dropping in network communication. Replica node detection scheme work well in fixed sensor network and do not work well in mobile sensor network. To detect these replica node attacks, Sequential Probability Ratio Testing (SPRT) that is speed measurement testing method is used. The proposed system shows the problem of sensor node failure. If a sensor node fails because of energy depletion we need to choose alternative sensor for that particular region. Then energy threshold for each sensor will be fixed, if it reaches that threshold it will inform the base station about the death. The base station should route another near-by energy-efficient sensor node to collect sensed data from that particular failed region. This paper show analytically and through ns2 simulation experiments that the scheme detects replica node in an efficient and robust manner.
