PERFORMANCE AND EFFECTIVENESS OF SECURE ROUTING PROTOCOLS IN MANET

Mobile adhoc network (MANET) is a temporary network setup for a specific purpose without help of any preexisting infrastructure. The nodes in MANET are empowered to exchange packet using a radio channel. The nodes not in direct reach of each other uses their intermediate nodes to forward packets. (MANET) environment of MANET makes it vulnerable to various network attacks. A common type of attacks targets at the underlying routing protocols. Malicious nodes have opportunities to modify or discard routing information or advertise fake routes to attract user data to go through themselves. Some new routing protocols have been proposed to address the issue of securing routing information. However, a secure routing protocol cannot single-handedly guarantee the secure operation of the network in every situation. The objectives of the paper is to study the performance and effectiveness of some secure routing protocols in these simulated malicious scenarios, including ARIADNE and the Secure Ad hoc On-demand Distance Vector routing protocol (SAODV)
