Design of a media stream relay engine on the Android OS

Abstract

The hierarchical network structure is proposed as a solution to the problem of decreased network performance for large-scale multimedia delivery in a single wireless LAN environment. However, the network structure on the Android OS is used for media streaming service; the role of the source device is important because a group owner delay causes a performance problem in which streaming data transmission to all Wi-Fi direct network groups creates a bottleneck. For a solution to these problems, we propose the media stream relay engine architecture and describe sequence diagrams for the development of a relay engine on the Android OS.
