Abstract
Vehicular Networks represent one of the main topics in the communication systems area. Increased deployment of vehicular networks together with new possibilities for Internet Protocol Television (IPTV) services has spurred the interest in providing mobile IPTV via vehicular networks. Provisioning of IPTV services over vehicular networks can be expected to play a significant role in the next generation of TV systems. Users will choose IPTV based on the Quality of Experience (QoE). Among QoE measures, TV channel availability is one of the most significant. In this paper, we investigate the channel availability in IPTV services with different traffic intensity and a varying number of TV channels offered to find out the acceptable availability of TV channels or the Call Blocking Probability (CBP) in our study. Comprehensive experiments are carried out by means of our own simulation tool, i.e., a Monte Carlo simulator to conduct the evaluations for numerous scenarios taking into account realistic IPTV user behavior.
