Extension of the ITS Station Architecture to Low-Power Pervasive Sensor Networks

Recent achievements in the Intelligent Transport System related research induced the need for further extensions of the newly standardized ITS Station Architecture, integrating an increasing number of emerging new technologies. In this paper preliminary results of the integration of the 6LowPAN protocols related to the use of the IEEE 802.15.4 based access technologies in the generalized ITS Station Architecture are presented. By means of this extension ITS communications open up new possibilities towards the inclusion of emerging technologies, such as the implementationof sensor networks in various safety and non-safety road and vehicle applications and the harmonization of the architecture with the principle of the Internet of Things. The proof of concept implementation of the design has been integrated into a multimodal V2X road-safety scenario, where the sensor network is attached to a roadside ITS Station using industrygrade ITS hardware and software. The results presented in this paper introduce the detailed functional evaluation of the application. By formalizing the results, provided by the functional analysis of the scenario, a feasible input is created for the standardization of the protocols in the ITS Station Architecture.
