A method for security enhancements in AODV protocol

An ad hoc network is a collection of wireless computers (nodes), communicating among themselves over possibly multi-hop paths, without the help of any infrastructure. Although many ad hoc network routing protocols have been proposed (DSR, AODV, ZRP etc), none of them considers the security problems. We put forward an efficient security mechanism based on the AODV routing protocol. In this security mechanism the double Hash authentications are adopted to protect routing information.
