The management of ad-hoc networks raises interesting problems, that are particularly challenging for networks of mobile nodes. Considering the inherent complexity of these systems, the development of distributed applications relying on wireless communication protocols would be greatly simplified by the use of specific tools for supporting testing and step-by-step debugging. In this paper we describe WISE, a flexible interactive simulation environment for the development of wireless ad-hoc networks consisting of mobile units. A graphical interface allows the user to create/delete nodes, change their positions and parameters, and select specific mobility models in order to verify the network behavior in dynamic conditions. The simulator also provides a useful support for the verification of agreement protocols, synchronization algorithms and distributed scheduling, allowing the user to display a step-by-step evolution of the algorithms in a suitable graphical representation

"Some popular network simulators like OPNET , ns-2 , OMNeT++  or GloMoSim  can simulate ad hoc networks. The others are dedicated to MANETs  or wireless sensor networks  simulation. The simulators provide the facility to simulate protocols in different layers, nodes mobility, energy consumption and various ad hoc networks application scenarios. "
[Show abstract][Hide abstract]ABSTRACT: Modeling and simulation are traditional methods used to evaluate wireless network design. This paper ad-dresses issues associated with the application of parallel dis-crete event simulation to mobile ad hoc networks design and analysis. The basic characteristics and major issues pertaining to ad hoc networks modeling and simulation are introduced. The focus is on wireless transmission and mobility models. Particular attention is paid to the MobASim system, a Java-based software environment for parallel and distributed sim-ulation of mobile ad hoc networks. We describe the design, performance and possible applications of presented simulation software. Keywords— ad hoc network, distributed simulation, mobile net-work, software systems.
