ABSTRACT
A MANET network is a group of sensor nodes with wireless communication competency. Eachnode acts as router in the network. There are a number of issues which affect the reliability of Ad-hocnetworks and limit their viability for different scenarios; lack of centralized structure within MANETrequires that each individual node must act as a router and is responsible for performing packet routingtasks; this is done using one or more common routing protocols across the MANET therefore the routing inMANETs is a key issue. The node mobility is the major reason behind changing topology. In this paperrouting protocols TORA, OLSR and GRP for mobile ad hoc network are compared on the basis of delay,network load and throughput. This comparative study shows that OLSR outperforms the rest of threeprotocols in terms of delay, network load and throughput.
