A mobile Ad-hoc network (MANET) is a peer 2 peer connecting network in it each node is act like a router. Due to this reason this network can be easily establish in any geographical location. a variety of of protocols have been selected & simulated for checking the data transferring consistency under different traffic densities.in this paper we compare & evaluate the performance of three popular routing protocols named as Ad-hoc On-demand Distance Vector (AODV) routing protocol, which is unipath and Dynamic source Routing (DSR) protocol &Destination-Sequenced Distance-Vector Routing (DSDV) is a table-driven routing protocol. In this paper we note that on comparing the performance of AODV DSR & DSDV, AODV incurs more routing overhead and packet delay than DSR & DSDV but it had better efficiency when it comes to number of packets dropped and packet delivery. The topology of the ad-hoc network depends on the transmission power of the nodes and the location of the mobile nodes, which may change from time to time. And due to the frequently changing topology routing & power consumption by nodes in transmission are the major challenges in ad-hoc wireless network.
