| Abstract | ||
| The Transmission Control Protocol (TCP) was designed to provide reliable end-to-end delivery of data over unreliable networks. In practice, most TCP deployments have been carefully designed in the context of wired networks. Ignoring the properties of wireless ad-hoc networks can lead to TCP implementations with poor performance. A mobile ad-hoc network is a collection of nodes that is connected through a wireless medium forming rapidly changing topologies. In this paper, two MANET (Mobile Ad-hoc NETwork) networks are connected across an IP-Based internet network. The MANET is connected to the IP network through a MANET gateway that is running a MANET routing protocol and an IP routing protocol (or static routing) on one of its interfaces. A MANET gateway is any wireless LAN router that has its MANET Gateway attribute enabled. The MANET routing protocol that used is AODV(Ad-hoc On Demand Distance vector) and the TCP variants that used is Taho, Reno and NewReno and the number of mobile nodes will be 3, 5, and 7 for each scenario that used in the simulation. After running the simulation, the results showed that the max throughput was in the scenario that has 5 nodes. This means that when increase the number of nodes above 5, the throughput will decrease. The simulation environment is designed and modeled and the result is collected under the powerful network simulation tool that called OPNET Modeler 14. | ||
