Network Simulation Environment for Visible Light Communication in Vehicular Networks

Abstract

There are multiple ways to conduct research in computer networking. If possible, real networks and systems are the most accurate way through which to experiment. However, in some cases, large-scale experiments are not feasible in real environments because of the costs, time, and manpower required. In such cases, simulation models and simulators provide researchers with appropriate tools to conduct large-scale and complex experiments.

This paper delivers ready-to-use Network Simulation Environment (NSE) for Visible Light Communication (VLC) simulations in vehicular networks. It implements basic vehicle model that allows multi-channel VLC communication. Models are flexible and ready to use to fit any shape and size of vehicles. Furthermore, NSE includes collision detection as well as Line-of-sight checking for communication channel availability. Although, this new NSE can be used (modified) on any ISO/OSI layer its primary purpose is a custom MAC protocol development and large-scale networks with mobility simulations. Implementation verification is successful, and it was based on simulating regular omnidirectional wireless communication based on new VLC model, both mobile and static layouts.
