| Summary: | Current vehicular networks are developed upon
commercial solutions based on cellular networks (CNs) or vehicular
ad-hoc networks (VANETs), both present in numerous
research proposals. Current approximations are not enough to
cover the communication necessities of several applications at
the same time, and they are not suitable for future vehicular
pervasive services. The vehicular network presented in this paper
fills the existent gap between solutions lacking in flexibility,
mainly supported by an infrastructure deployment, and those
highly local and distributed, such as sole-VANET approximations.
In this manner, an overlay communication platform which can
work over the CN basis has been designed and developed. This
architecture is complemented by an additional support of an
information system located at the infrastructure side. Moreover,
since most of the information received from current notification
services is not relevant for the driver, an additional subsystem has
been devised to provide adapted information to users. This has
been carried out by means of an ontology model which represents
users' preferences and contextual information. Finally, using a
whole prototype of the telematic platform, the performance of
this interring process has been evaluated to point out its impact
on the system operation. |
