Mobile Ad hoc NETworks(MANET) are characterized by multihop wireless connectivity, infrastructure less environment and frequently changing topology. The nodes acts as router and communicate to each other. This paper aims to provide a means of understanding the issues and protocol(OSPF, DSR, AODV, TORA, OLSR and DSDV) of MANET and investigating behavior of DSR,AODV,TORA protocol using metrics Throughput and Network Load. The Behavior analysis has been done by using simulation tool opnet 14.5 which is the main simulator. Mobile Ad-hoc NETwork (MANET) is a collection of wireless mobile nodes and connected in dynamic manner.
