Communications Management in Cooperative Intelligent Transportation Systems

Abstract : Cooperative Intelligent transportation Systems (Cooperative ITS) are the systems where multiple entities share information and tasks to achieve the ITS objectives (i.e. road safety, traffic efficiency and comfort). Today, ITS Station architecture is being specified in ISO and ETSI as a result of discussion and consensus of the researchers and developers in ITS domain. In the architecture, ITS Stations are essential entities, that are distributed in vehicles, roadside infrastructure, centers and mobiles, to achieve the ITS objectives. The vehicle and roadside ITS Stations organize Vehicular Ad-hoc Network (VANET) to adapt multi-hop and highly dynamic network topology. GeoNetworking is a great candidate for VANET because the geographic routing shows strength in dynamic topology. In addition to VANET, the ITS Station equips multiple wireless network interfaces and connects to networks with multiple paths, which is called multihoming. The objective of the study is to optimize the communication between ITS Stations by improved decision-making algorithm using inter-component information exchange in IP-based cooperative ITS. First, we develop IPv6 GeoNetworking to take the advantages of both IP and GeoNetworking. Seconds, we propose a cross-layer based path selection management by extending a Service Access Point (SAP) between the network layer and the management entity specified in the ITS Station Architecture. The extended SAP is designed as most abstracted as possible to adapt to the future development of the ITS Station architecture. The proposed system is designed and implemented as a prototype. The prototype implementation is evaluated in both ideal and realistic scenarios using up to four vehicles. The network performance measurement is processed, visualized and analyzed with web-based tools.
