Due to rapid advance in communication technology, the current demand is for wireless network than wired network. Wireless communication technologies have brought in fundamental changes in telecommunication and computer networking. Wireless networks include MANETs (Mobile Ad hoc NETworks) which is a collection of mobile nodes that communicate through wireless links and have no fixed topology or central administration. The task of sending packets between nodes called routing is done in MANET by some routing protocols. During last few years, a variety of different routing protocols that address multi-hop ad-hoc network have been developed.
