An Ad-hoc network is a collection of mobile nodes dynamically forming a temporary network without the use of any existing network infrastructure or centralised administer. Because of limited communication range among mobile nodes in ad-hoc network, several network hopes may be needed to deliver a packet from one node to another node in the wireless network. In recent years, a variety of different routing protocols addressing multi-hop ad-hoc network have been presented and their performance issues are discussed. This paper is subjected to comprehensive analysis among DSR,DSDV,AODV routing protocols of ad-hoc network with IEEE 802.11 Mac protocol in chain topology using Network Simulator-2(NS-2).Various important performance metrics of MANET such as Generated Packet Vs. no. of nodes, Received Packet Vs. no. of nodes, Packet delivery ratio Vs. no. of nodes, Total dropped packets Vs. no. of nodes, Average end to end delay Vs. no. of nodes are investigated to confirm the best routing protocol in the simulation environment.
