Abstract

Standard on-demand routing protocols in mobile ad hoc networks were not originally designed to deal with security issues. Mobile Ad-hoc Network is a collection of different type of nodes, which are connected to each other via wireless link. The security issue of MANETs in group communications is even more challenging because of involvement of multiple senders and multiple receivers. In this work we propose rushing attack for AODV. In Rushing attack, a malicious node rising the speed of routing process. In this proposed work AODV protocol is used for study of rushing attack . We also propose the improved routing scheme to defend ad hoc networks against rushing attacks using threshold and average path value calculation.
