Adaptive multisourcing video streaming in android phonesTripsta
The high demand for video streaming in mobile phones and the increase of
the amount of data transmitted in the Internet creates congestion that results in poor
video quality. This thesis develops and experiments with a video streaming
application that can transfer video data from multiple servers (multi-source), thus
taking advantage of bandwidth available in multiple paths and the capabilities of
multiple servers. The application amount of data requested from different servers
based on their throughput and includes fault control to tackle the case when a server CV of Christos Boursinos
2
stops being available. In addition to video streaming, the application can be used for
general file transfer. The video streaming application was developed for Android
Smartphones. Experiments show the performance of the application for different
scenarios, which include server faults and very low throughput and cases where
servers have different throughputs.
