With the growing popularity of social network and video sharing services, video sharing behaviors have become increasingly socializing. People can produce and share high-quality videos at any time and place using high-speed mobile networks and multimedia IoT devices, e.g., Android Things and smart TV Boxes. The multimedia IoT devices require higher bandwidth, memory, and computing resources to process and transmit multimedia contents such as audio, video, and image. In this paper, we propose a social-aware P2P video transmission strategy for multimedia IoT devices. In the proposed architecture, multimedia IoT devices are communicated using a peer-to-peer network. The peers in our work are represented by multimedia IoT devices with user interactions. Since users have their own friend list, the social links can be classified into different priority classes in accordance with their social relationships, e. g., family, friends, and others. The proposed strategy adopts weighted fair queue (WFQ) for P2P video transmission according to different queuing priority classes. Each priority class is given a weighted factor according to social relationship, current download progress, and mutual resource sharing contributions. By leveraging the inherent trust associated with social links, the proposed strategy can reduce the impact of free riders and give users good video sharing and watching experiences with multimedia IoT devices.
