“…There are some recent efforts on live video streaming and multimedia over VANETs in the literature [7][8][9]. There also exist practical achievements for vehicle-to-infrastructure communications to build-up roadside-backbone-networks (RBNs): At the University of Rostock, an RBN architecture was elaborated including early prototype implementations assuming fixed access nodes along the roads that can be accessed by the vehicles by means of wireless communication [10]. It is also suitable to use this infrastructure for broadcasting IPTV or other multimedia services for vehicular users.…”

Vehicular ad hoc networks (VANETs) represent a quickly emerging area of communication that offers a wide variety of possible applications, ranging from safety to entertainment. Internet Protocol Television (IPTV) services as an entertainment application over VANETs is considered to play an important role in the future of intelligent transportation systems and vehicular infotainment systems. Quality of experience (QoE) has a strong impact when choosing adequate IPTV services for end users. Among QoE measures, TV Channel Availability (CA) is utmost important. In this work, we investigate the channel availability in IPTV services offered to vehicular users via different access network technologies. We focus on different traffic intensities and various number of TV channels and we predict the CA of TV channels and the Channel Blocking Probability (CBP) to be expected. The comprehensive simulation experiments for motor-highway scenarios are achieved by means of an own simulation tool which is based on a detailed IPTV user behavior model.

“…For this purpose, we select the main (southern) part of the city of Rostock (Germany), defined as a rectangle with the coordinates (54.082776, 12.107670, 54.094623, 12.152976). We select this medium-scale urban area due to our experience with the roads network within this area from previous research projects [13]. The OSM map is used in the scan stage, where 1791 SoIs could be extracted directly from the map using the PRONET software.…”

The deployment of efficient roadside networks is a necessity for ITS deployment. The main challenge for the roadside deployment is to find a satisfying or best distribution of RSUs on the roads network according to the given conditions in order to meet the requested requirements of the roads operator. Additionally, various factors affect this process such as traffic, infrastructure and topological characteristics of the roads. This paper introduces an Overlap based Greedy Method (OGM) as a basis for RSUs placement and can be applied on urban and rural roads. This method in its current development mainly considers the RSU coverage radius and the overlap rate into the RSUs distribution process. Moreover, a wide range of influencing factors is considered through the prioritization of Sites of Interest (SoIs). The OGM method is developed within the recently started PRONET project and is integrated into its software platform.The tests conducted on selected roads environment in the city of Rostock (Germany) ensure: (1) decrease in number of chosen SoIs for placement compared to the original scanned number of SoIs, and (2) full (continuous) coverage cannot be guaranteed for a roads network using only the available junctions.
