6LoWPAN conform ITS-Station for non safety-critical services and applications

This paper presents a novel architecture for supporting WSN applications in the field of Intelligent Transportation Systems. Besides the set of the so called CALM ISO-standards for vehicular environments, a low-cost roadside ITS-Station network is proposed. It is based on the Internet of Things paradigm and its applicability at delivering non safety-critical services and applications are evaluated by means of experimental tests on prototypes. Boards with both specific hardware and tailored software have been designed. Then a Wide Area Network testbed has been instantiated to support trials of representative use cases. The performance analysis shows that the network of SEED-EYE boards driven by a 6LoWPAN compliant ITS-Station software suite matches the application requirements in a broad set of domains. Moreover the advantages of the proposed system architecture over existing solutions based on expensive and general purpose technologies have been discussed. This activity has been approved for standardization purposes as work items at ISO TC 204 Working Group 16.
