Detection and Prevention of Blackhole Attack, Wormhole Attack in MANET Using ACO

A. Radhika, Dr. D.Haritha

(Mobile Adhoc network) is a infrastructure less network used for wireless communication. MANET can be built with the mobile nodes which can move anywhere at any time. This results into the dynamic topology of MANET. Each node is responsible for routing the message from one node to the other like a router, causes network more vulnerable to the different attacks. In this paper we will discuss  Black Hole Attack a type of DOS attack and Worm Hole Attack. The emphasis of this paper is find detection method and prevention of these attacks in manets using Antnet Routing algorithm based on Ant Colony Optimization(ACO) framework.
