Abstract :

Effectiveness of peer sharing in peer-to-peer streaming service relies on a large group of steady- and nearby accesses to the
same video. However, such an ideal scenario may be unrealistic for some popular mobile streaming services, like news
broadcast, where news clips are many but relatively short, users have diversity of interests and mobile devices have limited
buffering and communication capabilities available for peer sharing. For solving this problem, we propose a news-broadcaston-
demand (NBOD) system which offers customized news broadcast service. NBOD consists of two components, channel
manager and clip scheduler. The channel manager is responsible for categorizing news into several broadcast channels. The
clip scheduler is responsible for performing a customized news marquee service of a broadcast channel for each user according
to his/her preference. Different clip scheduling policies with different computational complexity are investigated with the
objective of exploiting the highest peer sharing possibility. Through simulation, we observe that NBOD can effectively organize
news-clip retrievals to leverage peer-sharing efficiency. Tradeoff between the performance and management overhead exhibits
a spectrum of design options.
