Ad Hoc Network Simulators Features

Abstract

The deployment of wireless applications or protocols in the context of MANETs, often requires stepping through a simulation phase. There are several popular simulators, such as OPNET Modeller, GloMoSim or NS-2. Since NS-2 is more frequently used in worldwide network societies we present our experiences gained with the use of NS-2 for simulations of wireless mobile ad hoc networks. Facing the problem of poor documentation for ad hoc networks, our research resulted in reach documentation for NS-2 trace files and behaviour of ad hoc networks. We observed the flexibility of NS-2 simulator, by the means of adding new application layers, change of existing routing protocols, and incorporating various extensions created outside the NS-2 development team.
