Routing protocols are interesting research area in Mobile ad-hoc network. The motivation behind research work is to explain performance evaluation of routing protocol in MANETs. It is quite difficult to determine which routing protocol is best. Each routing protocol has its own advantages and disadvantages. MANET has an open medium, changing its topology dynamically due to these characteristics so it can be accessible both legitimate users and malicious attackers. An ad hoc network is a collection of wireless mobile nodes that forms a temporary network without use of a predefined infrastructure or centralized administration. In this environment it may be necessary for each wireless mobile node to convey other nodes in forwarding a packet to its destination node due to the limited transmission, limited bandwidth and limited battery power of wireless network interfaces. Nodes are connected with each other through a wireless link in ad-hoc network. Each mobile node operates not only as a host but also as a router forwarding packets for other mobile nodes in the network. The nodes are free to join and left the network due to infrastructure less wireless network. Whenever a node in the network is down or leaves the network that causes the link between other nodes is broken. The affected nodes in the network simply request for new routes and new links are established. Routing is playing important role in mobile ad-hoc network (MANETs). Routing is providing paths b/w source and destination by using routing algorithms.
