We have implemented a realistic prototype of CloudMoV, deployed
on Amazon EC2 and Google App Engine, where EC2
instances serve as the mobile users’ surrogates and GAE as
the social cloud to handle the large volumes of social message
exchanges. We conducted carefully designed experiments
on iPhone 4S platforms. The experimental results prove the
superior performance of CloudMoV, in terms of transcoding
efficiency, power saving, timely social interaction, and scalability.
The experiments also highlight the drawbacks of the current
HTTP Live Streaming protocol implementation on mobile
devices [24] as compared to our proposed burst transmission
mechanism which achieves a 29.1%increase of battery lifetime.
