Mobile social applications have emerged in recent years. They explore social
connections among mobile users in a variety of novel scenarios, including
friend finding, message routing, and content sharing. However, efficiently supporting
resource-demanding delay-sensitive streaming applications on the mobile
platform remains a significant challenge. Research on such topics will naturally
widen the usage of mobile social applications. The solutions to the challenges
will provide suggestion on many related work. It is interesting and valuable to
explore the system performance and users’ experience in such scenarios.
Furthermore, users’ concern about social network is also significant to develop
a mobile social network application. It is important to detect users’ strategies
to communicate with others. That influences the network topologies and
provides biased connections. The strategy consists of various of aspects, most of
which are the user preference and user social attributes.
Focusing on this meaningful research field, we study collaborative VoD-type
streaming of short videos among small groups of mobile users, so as to effectively
exploit their social relationships. Such an application can be practically set in
a number of usage scenarios, including streaming of introductory video clips of
exhibition items to visitors’ mobile devices, such as in a museum. We analyze
users’ behavior strategies based on their social preference and social attributes.
We design SMS, an architecture that engineers such Streaming over Mobile Social
networks. SMS constructs a collaborative streaming overlay by carefully
inspecting social connections among users and infrastructure characteristics of
Bluetooth technologies. To improve the performance, we analyze the scatternet
structure of Bluetooth technology and propose appropriate scatternet structure
in our system. We evaluate our design based on prototype implementation on
the Android platform, as well as on a large emulation testbed. The results obtained
indicate that we are able to achieve a well-performed streaming system in
a mobile social network. / published_or_final_version / Computer Science / Master / Master of Philosophy
