Mobile Ad-hoc NETwork (MANET) is a self-configuring infrastructure less network of mobile devices connected by wireless links. In this network technology, simulative analysis is a significant method to understand the performance of routing protocols. In this paper, three protocols AODV, DSDV and DSR were simulated using Manhattan grid mobility model. The reactive (AODV, DSR) and proactive (DSDV) protocol's internal mechanism leads to considerable performance difference. The performance differentials are analyzed using NS-2 which is the main network simulator, NAM, AWK and were compared in terms of Packet Delivery Fraction (PDF), average end-to-end delay and throughput, in different environments specified by varying network load, mobility rate and number of nodes.
