Abstract

This paper discusses the stochastic and strategic control of 60 GHz millimeter-wave (mmWave) wireless transmission for distributed and mobile virtual reality (VR) applications. In VR scenarios, establishing wireless connection between VR data-center (called VR server (VRS)) and head-mounted VR device (called VRD) allows various mobile services. Consequently, utilizing wireless technologies is obviously beneficial in VR applications. In order to transmit massive VR data, the 60 GHz mmWave wireless technology is considered in this research. However, transmitting the maximum amount of data introduces maximum power consumption in transceivers. Therefore, this paper proposes a dynamic/adaptive algorithm that can control the power allocation in the 60 GHz mmWave transceivers. The proposed algorithm dynamically controls the power allocation in order to achieve time-average energy-efficiency for VR data transmission over 60 GHz mmWave channels while preserving queue stabilization. The simulation results show that the proposed algorithm presents desired performance.

Highlights

As actively discussed nowadays, virtual reality (VR) or augmented reality (AR) applications have received a lot of attention by industry and academia research organizations [1,2,3,4]
If the amount of transmit power allocation at VR server (VRS) is quite high, more bits will be processed from the queue within the VRS
This paper proposes a strategic stochastic control algorithm that is for the minimization of time-average expected power consumption subject to queue stability in distributed VR network platforms

Summary

Introduction

Virtual reality (VR) or augmented reality (AR) applications have received a lot of attention by industry and academia research organizations [1,2,3,4]. In order to provide mobile services in head-mounted VR displays in VR applications, establishing wireless connections between VR video storage (called VR server (VRS)) and head-mounted VR devices (VRD) is essential. The candidate wireless technologies should provide ultra-high-speed data communication speeds for transmitting VR video streaming without latencies. For massive high-volume and high-definition multimedia contents delivery, millimeter-wave (mmWave) wireless communication technologies are widely discussed nowadays [5,6,7]. In mmWave wireless communication research, 60 GHz wireless technologies are generally and widely considered [8,9,10,11] because it is only one standardized millimeter-wave wireless technology so called IEEE 802.11ad [12]. The 60 GHz wireless channel is explored for simultaneous large-scale massive multimedia information delivery based on following reasons:
