In 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. [--]
