While the demand of video streaming services (VSSs) over the mobile networks have been soaring, the capacity of wireless links cannot keep up with the traffic needs. The difference between traffic demand and the link capacity, together with time-varying link conditions, causes inadequate service quality of video streaming, such as long buffering delays and sporadic disruptions. In this paper, by leveraging...
Adaptive video streaming is an essential tool for improving the performance of video delivery over mobile networks. By dynamically switching between different bit-rate versions of the same video, adaptive video streaming can compensate for and adapt to the ever-changing network conditions inherent in today's 3G/4G networks. However, existing adaptive streaming algorithms, both academic and commercial...
Traditional video streaming can be performed in two ways such as Video on Demand (VoD) and Live Video Streaming (LVS). In recent days, live video streaming in mobile devices has many issues such as buffering, delay, low bandwidth, screen resolution, limited computational energy, storage resources and connectivity loss. There arises a need that Video Streaming users must have the capability to deliver...
Video streaming accounts today for more than half of the global Internet traffic. Content Delivery Networks (CDNs) are employed to provide scalable and reliable video streaming services. Typically, the delivery systems are provisioned to meet the expected peak demands which are due to time-of-day effects. However, such a sizing strategy may either not be able to handle unpredictable flash crowd scenarios,...
In this paper, we propose an optimization algorithm called Intelligent Bitrate Switching-based Adaptive Video Streaming (ISAVS) to address the key issue of bitrate switching in HTTP-based adaptive video streaming. Our proposed solution can provide the best possible video quality to users with minimum replay interruption, which is reported as one of the key video quality issues of on-line video streaming...
Peer-to-peer (P2P) systems are becoming increasingly popular due to their ability to deliver large amounts of data at a reduced deployment cost. In addition to fostering the development of novel media applications, P2P systems also represent an interesting alternative paradigm for media streaming applications that can benefit from the inherent self organization and resource scalability available in...
