Paper Abstract

Recently Internet P2P/overlay streaming has gained increasing popularity. While plenty of research has focused on streaming performance study, it is not quite known yet on how to efficiently serve heterogeneous devices that have different limitations on display size, color depth, bandwidth capacities, CPU and battery power, than desktop computers. Although previous work1 proposes to reuse intermediate information (metadata) produced during transcoding to facilitate runtime content adaption to serve heterogeneous clients by reducing total computing load, unbalanced resource contribution may pre-maturely exhaust the limited power of mobile devices, and adversely affect the performance of participating nodes and subsequently threaten the robustness of the whole system. In this work, we propose a Dynamic Bi-Overlay Rotation (DOOR) scheme, in which, we further consider resource consumption of participating nodes to design a dynamic rotation scheme that reacts to dynamic situations and balances across multiple types of resources on individual nodes. Based on the computing load and transcoding quality parameters obtained through real transcoding sessions, we drive large scale simulations to evaluate DOOR. The results show clear improvement of DOOR over earlier work.
