Abstract:

In this presentation, we study the performance of video streaming in
distributed communication systems. It starts with an introduction to
convex optimization and the associated duality properties. Then we will
show the relationship between this optimization principle and the
distributed communication systems, including Peer-to-peer networks,
wireless ad hoc networks and wireless visual sensor networks. We will
finally apply this principle to Video-on-Demand (VoD) over P2P systems to
address issues in a) optimal resource allocation, and b) network capacity
estimation. Simulation results will be provided to demonstrate the
effectiveness of the proposed method.
