The interest for making vehicular transportation safer and more efficient has increased exponentially in recent years. To develop such vehicular communication systems, accurate models for the propagation channel are needed. This work analyzes the channel properties of different wireless communication systems within a vehicular communication environment with deterministic modeling. Three different...
The use of wireless networks has been extended in an exponential growing in urban infrastructure environments. However, it is highly important to conduct previous radio propagation analysis when deploying a wireless sensor network in such complex scenarios. In this work, the radio wave characterization for ISM 2.4GHz Wireless Sensor Networks (WSN) for an urban infrastructure system assessed. This...
Transportation system is experiencing steady growth, with the aim of providing more efficient, reliable, and comfortable services, in the framework of intelligent transportation systems. Moreover, context aware environments are one of the main drivers in the achievement of smart cities and smart regions. In this paper, wireless sensor networks (WSNs) embedded in urban transportation systems will be...
The evolution of health systems derives in the implementation of Smart Health, integrated within the framework of Smart Cities and Smart Regions. In this context, vehicular communications provide additional means of interaction among users, administration and health professionals. In this work, characterization of wireless communication between ambulance and urban deployed access points will be analyzed,...
An interactive shopping cart to enable context-aware environments within large commercial areas is presented. A wireless sensor network was designed with specific nodes embedded within the shopping carts and infrastructure nodes in the shopping area. Due to the complexity of wireless propagation, given the large amount of obstacles and the inclusion of users, an in-house deterministic method based...
The combination on an algorithm based on Geometrical Optics (GO) and diffraction calculation on the basis of the Uniform Theory of Diffraction (UTD) is presented in this paper. The aim is to improve the basic Ray Launching code, based on GO, which takes into account reflected and refracted rays. With the UTD extension, further propagation of diffracted rays is also considered. The comparison with...
