Paper Title
Performance Comparison of Ad Hoc Network with NS2 Simulator

Abstract
These devices can communication with other nodes that immediately within their radio range or one that is outside their radio range. For the later, the nodes should deploy an intermediate node to be the router to route the packet from the source toward the destination. The Wireless Ad-hoc Networks do not have gateway, every node can act as the gateway. Although since 1990sí, lots of research has been done on this particular field, it has often been questioned as to whether the architecture of Mobile Ad-hoc. Networks is a fundamental architecture. The comparison of these protocols is base on different performance metrics, which are throughput, packet delivery ratio, routing overheads, packet drop and average end to end delay. The performance evaluation has been done by using simulation tool NS2 (Network Simulator) which is the main simulator. Main objective of this paper is to evaluate the performance of various ad-hoc networks routing protocols viz. DSDV (Destination Sequence Distance Vector), DSR (Dynamic Source Routing) and AODV (Ad-hoc On Demand Distance Vector) Keywords- Ad HOC, DSDV, AODV, Throghput.
