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.

“…Vehicular networks are usually short range communication networks, and the communicating devices can communicate directly with each other (V2V) [3] or with/through the infrastructure (V2I) [29] using the installed OBUs. Vehicular networks are characterized by the high-speed mobility, directions, and heterogeneous wireless network conditions that cause frequent route disruptions and changes in the network topology [12].…”

Quality of service and mobility aware in-vehicle telescreen service architecture

et al. 2017

Original scientific paper This paper presents an architecture for providing quality of service (QoS) and mobility-aware telescreen services in vehicular networks, named "in-vehicle telescreen" (IVT). Providing seamless imagery effect is a key challenge in the distribution of high-resolution and delay-sensitive infotainment IVT services under mobile and varying network conditions. In the IVT architecture, new functions of information and service quality management are introduced to manage the user registrations, service advertisements, network information, and service quality. We propose an adaptive selection of application QoS parameters and an IVT handover decision mechanism for providing seamless imagery effect and enhance user's multimedia perception. The proposed architecture can provide a sustainable channel rate based selection of content source, media resolution, and codec to improve the perceived visual quality. Furthermore, the paper presents a Link Expiration Time and Received Signal Strength Indicator based IVT handover decision mechanism that can minimize the number of handovers by selecting a stable path. An extensive simulation is performed to show the effectiveness of the proposed mechanisms. Keywords: handover decision mechanism; in-vehicle telescreen; quality-of-experience; quality-of-service; vehicular networks Arhitektura kvalitete usluge i usluge tele-ekrana u pokretnim voznim mrežamaIzvorni znanstveni članak U radu se predstavljena arhitektura za osiguranje kvalitete usluge (quality of service -QoS) i usluge tele-ekrana u voznim mrežama koje reagiraju na pokretljivost, nazvane teleekran unutar vozila -"in-vehicle telescreen" (IVT). Osiguranje nepromjenljive slike je ključni izazov u pružanju IVT usluga visoke rezolucije u mobilnim uvjetima i uvjetima variranja mreže. U IVT arhitekturi uvode se nove funkcije upravljanja kvalitetom informacija i usluga u vođenju registracije korisnika, oglašavanju usluga, obavijesti o mreži, i kvaliteti usluge. Predlažemo prilagodljiv izbor QoS parametara te mehanizam za donošenje odluke o prekapčanju IVT kako bi se osigurala čista slika i poboljšala multimedijska percepcija korisnika. Predloženom se arhitekturom može osigurati izbor izvora sadržaja zasnovan na prosječnoj kanalskoj brzini, rezolucija medija i kodek (koder-dekoder) za poboljšanje postojane vizualne kvalitete. Nadalje, u radu se predstavlja mehanizam za donošenje odluke o prekapčanju IVT temeljen na pokazivaču vremena isticanja veze i pokazivaču snage primljenog signala koji može smanjiti broj prekapčanja izborom stabilne staze. Provedena je opsežna simulacija kako bi se pokazala učinkovitost predloženih mehanizama. Ključne riječi: mehanizam za donošenje odluke o prekapčanju; teleekran u vozilu; kvaliteta iskustva; kvaliteta usluge; vozne mreže

“…Moreover, Abdollahpouri has done similar investigations for WiMAX-based access networks [16] by which IPTV is offered to either non-mobile or (slightly) mobile users [17]. More recent research, done by Momeni et al, has started to study the availability of IPTV in the context of VANETs with their rather specific mobility models [18,19]. All of these investigations are exclusively based on the usage of simulation models.…”

In vehicular ad hoc networks (VANETs), besides the original applications typically related to traffic safety, we nowadays can observe an increasing trend toward infotainment applications, such as IPTV services. Quality of experience (QoE), as observed by the end users of IPTV, is highly important to guarantee adequate user acceptance for the service. In IPTV, QoE is mainly determined by the availability of TV channels for the users. This paper presents an efficient and rather generally applicable analytical model that allows one to predict the blocking probability of TV channels, both for channel-switching-induced, as well as for handover-induced blocking events. We present the successful validation of the model by means of simulation, and we introduce a new measure for QoE. Numerous case studies illustrate how the analytical model and our new QoE measure can be applied successfully for the dimensioning of IPTV systems, taking into account the QoE requirements of the IPTV service users in strongly diverse traffic scenarios.
