Integration of Wireless Sensor Networks in Intelligent Transportation Systems within Smart City Context

Abstract:

The use of Vehicular Ad Hoc Networks has been exponentially growing in the last few years. Because of that, it is highly important to conduct previous radio propagation analysis when deploying vehicle-to-vehicle (V2V) or vehicle-to-infrastructure (V2I) networks in urban scenarios, for Intelligent Transportation System (ITS) applications. In this work, the radio wave characterization for an urban infrastructure wireless communication system has been assessed for different frequencies. Two different realistic scenarios in which traffic lights, vehicles, people, buildings, vegetation and urban environment, have been implemented in an in-house 3D Ray Launching code. Results provide radio planning information before the deployment of Wireless Sensor Networks in terms of coverage, capacity and energy efficiency of the network.
