Resource allocation for video streaming in wireless environment
Shahrokh Valaee, Jean‐Charles Grégoire · 2003
This paper focuses on the development of a new resource allocation scheme for video streaming in wireless networks. The technique utilizes the /spl epsi/-weak burstiness curve which has been defined as the (1 - /spl epsi/)-percentile of the maximum burstiness curve. We show that the /spl epsi/-weak burstiness curve is a convex non-increasing function of the service rate. We also devise a "water-filling" algorithm to obtain the empirical /spl epsi/-weak burstiness curve. The technique has been applied to MPEG-4 encoded video traces. The numerical studies show that if the /spl epsi/-weak burstiness curve is used for resource provisioning, a considerable percentage of bandwidth will be saved.
