Security has become a prime concern so as to present protected communication in Wireless as well as wired environment. Ad hoc networks are illustrated by multi-hop wireless connectivity and recurrently changing network topology which have made them infrastructure less. The wireless links in this network are very error prone and can go down frequently due to mobility of nodes, interference and less infrastructure. A routing protocol is needed whenever a packet needs to be transmitted to a destination via number of nodes and numerous routing protocols have been proposed for such kind of ad hoc networks. It is advantageous to know the performance of various protocols under different scenarios for various metrics.
