QoE-Oriented Resource Allocation for 360-degree Video Transmission over Heterogeneous Networks
Immersive media streaming, especially virtual reality (VR)/360-degree video
streaming which is very bandwidth demanding, has become more and more popular
due to the rapid growth of the multimedia and networking deployments. To better
explore the usage of resource and achieve better quality of experience (QoE)
perceived by users, this paper develops an application-layer scheme to jointly
exploit the available bandwidth from the LTE and Wi-Fi networks in 360-degree
video streaming. This newly proposed scheme and the corresponding solution
algorithms utilize the saliency of video, prediction of users' view and the
status information of users to obtain an optimal association of the users with
different Wi-Fi access points (APs) for maximizing the system's utility.
Besides, a novel buffer strategy is proposed to mitigate the influence of
short-time prediction problem for transmitting 360-degree videos in
time-varying networks. The promising performance and low complexity of the
proposed scheme and algorithms are validated in simulations with various
360-degree videos.Comment: submitted to Digital Signal Processin
