Different Methods and Approaches for the detection and removal of Wormhole Attack in MANETS

— Mobile Ad hoc NETwork (MANET) makes it exposed to a variety of network attacks. MANET due to its wireless transmission nature contains more security issues as compared to wired networks .These security issues are very important to deal with so as to make network secure. Wormhole attack also called as tunnelling attack is very difficult to detect. wormhole generally possess two properties In this paper we have studied the wormhole attack along with its properties and various method have been discussed for identification , removal, and prevention of wormhole attack and then they have been compared to one another so that effective methods should come forward .This study aims to combine some methods or to modify the one.
