ARAN Immunization against Wormhole Attack

Ad-hoc networks refer to temporary networks which form for special purposes. Mobile ad-hoc networks (MANETs) are networks which use no network assisting element for routing, but every node has the role of router and actively participates in data forwarding. Security problems in MANETs are specified and investigated separately, because in these infrastructureless networks, in addition to all available problems in a wired or wireless network, there are some more problems. Since all connections are available in wireless form and they are audible, so they can be changeable. Also nodes themselves are involved in routing, so existence of a malicious node can lead to the destruction of the network and one of the most important challenges in these networks is providing of a secure routing protocol algorithm. Here we investigate one of the secure routing protocols (ARAN) and try to increase its security against wormhole attack which is one of the famous attacks .This kind of attack by cooperation of two or more nodes create for transferring of information from their private network or tunnelling of information. Then we will try to decrease wormhole attacks through this method and also minimize problems resulting from using packet leash with different methods and changes its structure.
