Performance of AOMDV routing protocol is more reliable and efficient than other routing protocols in ad hoc network. It provides multipath routing which means it follows multipath to send data packets from source to destination. It do not follow multipath simultaneously but when failure occurs in one path, then it immediately discovers new path and then delivers packets up to destination. When any DDOS attack occurs in a network, then it degrades the performance of AOMDV routing protocol. Under this attack AOMDV consumes more power and bandwidth which further degrades the performance and makes it unreliable. In this paper a new protocol is proposed named EAOMDV i.e. Enhanced Ad hoc on demand distance vector routing protocol. It is enhance version of AOMDV which overcomes the problems that occurs during attack in AOMDV. In this, DDOS flooding attack is introduced. Then performance of existing and proposed protocol is measured under various parameters i.e. throughput, packet delivery ratio, end to end delay and normalized routing load.
