Abstract
Virtual reality (VR) imaging, with its 360° perspective, poses bandwidth challenges for video transmission. To solve the challenge, tile-based streaming delivers only the viewed portion of the video rather than the whole video. However, the influence of VR sickness and social relations on tile quality assignment has not been fully investigated. In this paper, we formulate Tile and Handover Management regarding VR sickness and Social relation (THMVS) in an adaptive 360° video streaming system for mobile users, along with VR sickness alleviation. We propose a multi-armed bandit (MAB) algorithm with confidence bound-based reward and cost estimation to evaluate video quality and VR sickness. Our algorithm dynamically adjusts the tile quality and weighting factor of each user’s VR sickness increment according to user social relation, decelerating the VR sickness accumulation of susceptible individuals. Simulation results manifest that our algorithm outperforms existing video streaming algorithms regarding video quality and VR sickness accumulation.
