Performance Evaluation of Standard and Security Extended Protocols in MANET

An ad hoc network is a group of wireless mobile nodes, in which individual nodes cooperate by forwarding packets for each other to allow nodes to communicate beyond direct wireless transmission range. There are many protocols are there routing compare to standard protocols security enabled protocols are few. There are lot of security types one of the types is secure the route which packets flow through. Secure routing protocols extended from standard protocols. This paper compares four protocols, two standard and two secure protocols that are extended from the standard protocols. The two standard protocols are AODV, DSR and two security extended protocols are Ariadne and FACES by using NS2 simulator. AODV and DSR are basic protocols and they are already implemented and compared in many situation. FACES algorithm works by sending challenges and sharing friend Lists to provide a list of trusted nodes to the source node through which data transmission finally takes place. Ariadne is a secure on-demand ad hoc network routing protocol. Ariadne prevents attackers or compromised nodes from tampering with uncompromised routes consisting of uncompromised nodes. Two scenarios are consider in MANET and at last conclusion will be presented, that the efficiency of the secure protocols over standard protocols.
