(2017) Optimization and design of wireless systems for the implementation of context aware scenarios in railway passenger vehicles. IEEE Transactions on Intelligent Transportation Systems, 18(10), 2838-2850. https://doi.org/10.1109/TITS.2017.2688858.1524-905010.1109/TITS.2017.2688858https://academica-e.unavarra.es/handle/2454/47028In this paper, intra-wagon wireless communication performance is analyzed, in order to account for inherent scenario complexity in the deployment phase of wireless systems toward the implementation of a context-aware environment. A real commercial passenger wagon has been simulated by means of an in-house-developed 3-D ray launching code, accounting for embedded wagon elements as well as variable user densities within the passenger wagon. Onboard measurements of a designed and deployed wireless sensor network are obtained, showing good agreement with wireless channel estimations for two different frequencies of operation. Energy consumption behavior and user density impact have also been analyzed and estimated as a function of network topology and the operational mode. These results can aid in wireless transceivers deployment configurations, in order to minimize power consumption, optimize interference levels, and increase overall service performance.application/pdfeng© 2017 IEEE.
