Availability evaluations for IPTV in VANETs with different types of access networks

“…In this case, again assuming three lanes per direction, SP [1] = 100 km/h, SP [2] = 120 km/h and SP [3] = 140 km/h, …”

“…We assume the highway has three lanes per direction and that SP [1] = 80 km/h and SP [2] = SP [3] =100 km/h, respectively, and the minimum distance between the vehicles on the three lanes are d avg [1] = 20 m and d avg [2] = d avg [3] = 30 m (same for each direction). Besides investigating situations with exactly these minimum distances, we are going to study this scenario with 2 × Minimum d avg [i] and also 4 × Minimum d avg [i] .…”

“…In this mobility scenario, we assume SP [1] = 110 km/h, SP [2] = 140 km/h and SP [3] = 160 km/h, respectively and thus the minimum distances between the vehicles are d avg [1] = 35 m, d avg [2] = 45 m and d avg [3] = 55 m. Moreover, different distances of 2 × Minimum d avg [i] and also of 4 × Minimum d avg [i] are also studied in this scenario.…”

“…However, some efforts to evaluate CBP for IPTV with different types of access networks have been done. In [2], J. Lai et al proposed to decrease the CBP and to improve the channel availability in DSL-based access networks. J. Lai et al [3,4] investigated the CBP not only in stationary but also in more realistic peak-hour scenarios and provided algorithms which allow one to reduce CBP efficiently.…”

Abdollahpouri et al, in [5], suggested a realistic model to reflect the typical behavior of IPTV users and studied the influence of different channel popularities in WiMAX-based IPTV systems.…”
