Query: Popularity based Bandwidth Allocation for Video Broadcast/Multicast over
  Wireless Networks   Recently, video broadcast/multicast over wireless networks has created a
significant interest in the field of wireless communication. However, the
wireless resources have limitations to broadcast/multicast many video sessions
at the same time with the best quality. Hence, during the video transmission
through wireless networks, it is very important to make the best utilization of
the limited bandwidth. When the system bandwidth is not sufficient to allocate
the demanded bandwidth for all of the active broadcasting/multicasting video
sessions, instead of allocating equal bandwidth to each of them, our proposed
scheme allocates bandwidth per video session based on popularity of the video
program. Using the mathematical and simulation analyses, we show that the
proposed scheme maximizes average user satisfaction level. The simulation
results also indicate that a large number of subscribers can receive a
significantly improved quality of video. To improve the video quality for large
number of subscribers, the only tradeoff is that a very few subscribers receive
slightly degraded video quality.
