VI. CONCLUDING REMARKS AND FUTURE WORK
This paper presents our view of what might become a trend
for mobile TV, i.e., mobile social TV based on agile resource
supports and rich functionalities of cloud computing services.
We introduce a generic and portable mobile social TV framework,
CloudMoV, that makes use of both an IaaS cloud and a
PaaS cloud.
The framework provides efficient transcoding services
for most platforms under various network conditions and
supports for co-viewing experiences through timely chat exchanges
among the viewing users.
By employing one surrogate
VM for each mobile user, we achieve ultimate scalability of the
system.
Through an in-depth investigation of the power states
in commercial 3G cellular networks, we then propose an energy-
efficient burst transmissionmechanism that can effectively
increase the battery lifetime of user devices.
