WiDiSi: A Wi-Fi Direct Simulator

This paper describes WiDiSi, a research-oriented prototype simulator for Wi-Fi Direct networks. WiDiSi is provided as an extension of PeerSim, a widely-used, open-source simulation framework for large-scale peer to peer networks. WiDiSi's main goal is to allow Android Wi-Fi direct applications to be easily tested in large-scale dynamic scenarios. In this article, we explain how WiDiSi was modeled and present its general architecture. We also provide evaluation results that show the correctness and the capabilities of the simulator.
