Ad-hoc networking allows portable equipment to establish link independent of a central infrastructure. This research work shows that there is no middle infrastructure and that the equipment can move randomly gives rise to various thoughtful of problems, such as routing and security. In this work the problem of routing is deal it. In this work pre-owned Ad-hoc routing protocols, such as AODV, DSR that propose solutions for routing within a mobile Ad-hoc network. Since there is an interest in link in the middle not only mobile equipment in an Ad-hoc network, but also among a mobile apparatus star in an Ad-hoc network and a fixed apparatus star in a fixed. The Ad-hoc routing protocols need to be modified. In this research work Ad-hoc routing protocol AODV and DSR is used and modified to examine the interconnection among a mobile ad hoc network and the Internet. The Network Simulator 2 (NS-2) is a popular and powerful simulation environment, and the number of NS-2 users has escalation greatly in recent years. Although it was basically created for wired networks, NS-2 has been continued to work with wireless networks, further wireless LANs, mobile ad hoc networks (MANETs), and sensor networks.
