An Efficient and Reliable Approach for Wormhole Attack Detection and Prevention In Wireless Sensor Network

Networking

Wireless Sensor networks are comprised of many small and resource constrained sensor nodes that are deployed in an environment for many applications which require unattended, long-term operations. They are vulnerable to many kinds of attacks because of no specific network topology. Wormhole attack is one of the severe attack used to destabilize or disable wireless sensor networks. The idea behind this attack, is two or more colluding attackers record packets at one location, and tunnel them to another location for a replay at that remote location. This makes the tunnelled packet arrive either sooner or with a lesser number of the hopes compared to the packets transmitted over normal multi hop routes. Routing mechanisms which rely on the knowledge about distance between nodes can get confuse because wormhole nodes fake a route that is shorter than the original one within the network. In these paper we work on trust mechanism for detect and prevent wormhole attack
