AS-aware Relay Selection Mechanism for Multiparty Streaming Service in Overlay Network

It has been shown that relay nodes can improve
the quality of streaming data delivery in an overlay network. Therefore, many researchers have proposed methods for relay node selection. However, existing methods have some issues, such as scalability, long service start-up time, and not on multiparty service. In this paper, we propose an AS-aware relay selection (ASRS) mechanism to enhance the efficiency of multiparty streaming service in overlay networks. We verified and evaluated ASRS using ns2 network simulator. The experimental results show that ASRS has a short relay selection time. It can also reduce the bandwidth need of multipoint control unit (MCU) effectively so as to supports more users.
