On the Adaptive THz System for Mobile VR Users in Smart Factories

Dynamic Virtual Reality (VR) applications with high speed Terahertz (THz) channels are emerging and being deployed in future smart factories. However, the disadvantage of THz channels is that they are susceptible to changed transmission states due to mobility, leading to low fault tolerance and throughput. To this end, we propose an adaptive algorithm operated under the control plane for configuring THz systems with a dynamic VR user adaptively by choosing the best coding and modulation schemes with the best code rate and throughput based on the THz transmission positions of the VR user. Our adaptive algorithm can generate the adaptive system configurations when a VR user moves or stops at any position to satisfy the quality of THz service. The results show that our algorithm can achieve maximum throughput and fault tolerance when the VR user stops moving and always satisfies the threshold of BER allowed when the VR user moves in analyzed network scenarios.
