Resumo:
Vehicular Networks are becoming more popular every day, being widely applied in the
context of the Internet of Vehicles (IoV), a variation of the Internet of Things (IoT) where
its objects are automobiles. These networks are intended to provide communication between
two or more vehicles, or between a vehicle and a road infrastructure, which can communicate
with external networks. Thus, these networks propose to benefit their users through applications,
which can be safety-related, such as collision avoidance, or non-safety-related, such as
real-time traffic information. However, some rules must be met for this structure to be well
implemented. As it is a network that needs the reception of information almost instantaneously,
especially in safety-related applications, it needs extremely low latency and considerably
high bandwidth. Furthermore, there needs to be interoperability between IoV devices
and external IoT services, such as in infotainment applications. Therefore, it is necessary
to study application-level solutions that enhance these services. Considering this problem,
this work evaluates and compares specific application protocols for Vehicle Networks with
general-purpose protocols used in IoT systems, to identify which ones can present positive
results regarding connectivity and interoperability needs. This evaluation also investigates
whether these protocols are suitable for use with mobile computing systems on the edge,
considering specific scenarios for Vehicular Networks, such as the grouping of vehicle platooning,
in addition to a simulation based on the city of Campina Grande. The evaluation
results show that Constrained Application Protocol (CoAP) is viable for use in Vehicular
Networks, enabling a communication delay within the expected range for these networks,
and favoring interoperability with external services, such as in a streaming application.
