Integrated Extensible Simulation Platform for Vehicular Sensor Networks in Smart Cities

This paper presents an integrated extensible simulation platform BHU-VSim for Vehicular Sensor Networks (VSNs), which aims to support general simulation environment for typical vehicular applications in smart cities. To deploy urban traffic scenario, the authors propose a hierarchical object structure to manage entities with different movement models in the network. Furthermore, they design a general data container to present different kinds of data transferred and provide two schemes to generate data packages. Regarding transmission control, the platform includes three components: task scheduling, storage management, and routing deployment. They support importing external routing protocols and configuring relevant parameters to satisfy various transmission requirements. Finally, an instance application, real-time traffic monitoring, and an example of statistical analysis are introduced to prove the practicality and accuracy of the simulator.
