Development of a high performance Wireless Mesh Network for video streaming

摘要

Wireless Mesh Network (WMN) is a fast developing intelligent community network to provide multimedia services to the residents. With the latest development of technologies in broadcasting and smart mobile devices, to view videos on these handheld devices via WMN will become an essential lifestyle in the future. However, current WMN faces challenges to deliver videos to multiple users because of the constrained wireless medium. This paper addresses the challenges of video streaming in WMNs by providing a high performance design architecture to allow smooth delivery of videos. This includes the load balanced routing via multiple gateways and over multi-paths, efficient usage of the bandwidth by multicast routing, effective congestion control for video streaming and scalable video streaming to deliver videos to various devices at the same time. Practical implementation demonstrated the effectiveness of the current design and development.
