Multi-Tier CloudVR

The availability of high bandwidth with low-latency communication in 5G mobile networks enables remote rendered real-time virtual reality (VR) applications. Remote rendering VR graphics a cloud removes the need for local personal computer and augments weak processing unit capacity stand-alone headsets. However, to prevent added network latency from ruining user experience, locally navigable viewport that is larger than field view HMD necessary. size required depends on latency: Longer requires streaming more content. In this article, we aim utilize multi-access edge computing assist backend such interactive VR. Given dependency between amount quality content streamed, our objective jointly optimize tradeoff average video delivery latency. Formulating problem as mixed integer nonlinear programming, leverage interpolation client’s frame overall convert programming model then design efficient online algorithms solve it. results simulations supplemented by real-world data reveal enabling desired balance latency, algorithm particularly achieves improvements about 22% 12% term 8% compared respectively order-of-arrival, threshold-based, random-location strategies.
