Collaborative P2P streaming based on MPEG-DASH for smart devices

摘要

Due to widespread wireless broadband Internet, multimedia streaming using smart devices has become one urgent application. In this paper, we focus on how to improve the transmission performance when mobile users request multimedia streaming service on their smart devices. In this paper, smart devices are grouped to form one localized ad-hoc network using Bluetooth according to their social behavior and geographical locations. That is, if some users are willing to share the same multimedia objects and nearby within the Bluetooth coverage, they should cooperate to download the multimedia streams using the peer-to-peer (P2P) protocol through the Internet and the Bluetooth ad-hoc network simultaneously. Therefore, the proposed scheme based on the help of Bluetooth ad-hoc network not only offloads the inter-ISP traffic of P2P overlay network, but also saves the battery power of smart devices.
