Detecting Wormhole Attacks in Wireless Sensor Networks
Wormhole attacks can destabilize or disable wireless sensor networks. In a typical wormhole attack, the attacker receives packets at one point in the network, forwards them through a wired or wireless page link with less latency than the network links, and relays them to another point in the network. This paper describes a distributed wormhole detection algorithm for wireless sensor networks, which detects wormholes based on the distortions they create in a network. Since wormhole attacks are passive in nature, the algorithm uses a hop counting technique as a probe procedure, reconstructs local maps for each node, and then uses a “diameter” feature to detect abnormalities caused by wormholes. The main advantage of the algorithm is that it provides the locations of wormholes, which is useful for implementing countermeasures. Simulation results show that the algorithm has low false detection and false toleration rates.
Keywords: Wireless sensor networks, wormhole detection, distributed algorithm
Unique characteristics like limited bandwidth, limited battery power and dynamic topology makes Wireless sensor network (WSN) vulnerable to many kinds of attacks. Therefore interest in research of security in WSN has been increasing since last several years. Infrastructure less and self-governing nature of WSN is challenging issue in terms of security. Wormhole attack is one of the severe attack in wireless sensor network. In this paper, the techniques dealing with wormhole attack in WSN are surveyed and a method is proposed for detection and prevention of wormhole attack. AOMDV (Ad hoc On demand Multipath Distance Vector) routing protocol is incorporated into these method which is based on RTT (Round Trip Time) mechanism and other characteristics of wormhole attack. As compared to other solution shown in literature, proposed approach looks very promising. NS2 simulator is used to perform all simulation.
Introduction
Sensor nodes are used to perform communication in wireless sensor network. Nodes in network here communicate
directly with each other using wireless transceivers with no fixed infrastructure. Sensor nodes are deployed in large
number to monitor the environment or system by measurement of physical parameters such as pressure,
characteristic of object temperature and their relative humidity or motion. Each node of the sensor network consist
of the three subsystems: the processing subsystem which performs local computations on the sensed data, the sensor
subsystem which senses the environment and the communication subsystem which is responsible for message
