Abstract
Ad hoc networks are characterized by multihop wireless connectivity, frequently changing network topology and the need for efficient dynamic routing protocols. Efficient routing protocols can provide significant benefits to mobile ad hoc networks, in terms of both performance and reliability. Many routing protocols for such networks have been proposed so far. The scope of this paper to test routing performance of four different routing protocols (AODV, OLSR, FSR and LAR) in variable pause times and node density in large-scale networks. We have used QualNet Simulator 4.0 from Scalable Networks to perform the simulations. This paper describes the different routing protocols and the experiment setup and finally presents and discusses the results.
