Secure route discovery against wormhole attacks in sensor networks using mobile agents

Abstract

Wireless sensor networks have many potential areas of applications. Wormhole attack is one of attack in sensor network. For wormhole attack, the attackers need not to compromise any sensor nodes, where as attacker receives packet at one location tunnels them to another location. Later, the attacker can tamper the data, messages, or selectively forward data messages to disrupt the functions of the sensor network. It place attacker in very powerful position relative to other nodes in network. This paper discusses Secure Routing protocol against Wormhole Attacks in sensor network (SeRWA). SeRWA provides secure route with false positive. We use mobile agent to reduce false positive in SeRWA protocol. The literature survey has been done on various techniques used to defense against wormhole attack, advantages and disadvantages of each also studied. Researchers have used some special hardware such as the directional antenna and the precise synchronized clock to defend the network against wormhole attacks.
