Abstract: A MANET is an independent network communication through a wireless medium without requiring any fixed infrastructure, where a target node is not in the direct range of transmission over a sender node, and where midway nodes are needed in order to forward packets. The midway nodes here are not only the host but also acts as a router for hand over packets. Nonetheless, it is very simple to attack the defenseless character of the ad hoc networks by malicious node like the dropping or hand over of forged data etc. As the need for dynamic network is constantly developing, security problems in the network layer in particular must be properly solved according to MANETs. This paper discusses a series of routing violations and proposes an improvement in AODV’s design to authenticate route requests using digital signatures to prevent malicious node attacks.
