HoIP Performance for Tactile Internet over 5G Networks: A Teleoperation Case Study

The Tactile Internet (TI) is expected to shift the paradigm of Internet from content delivery to skill delivery. To enable this type of delivery, IEEE 1918.1 working group started working on the standardization of TI for the realization and the deployment of different use cases involving different haptic applications. Indeed, the exchange of haptic signals is time critical, with a delay requirement of 1-10 ms. We propose a conceptual teleoperation system based on 5G new radio (5G NR) as access technology to the network. The control of the proposed system requires a low End-to-End delay (E2E) to guarantee a stable system operation and correct haptic feedback. For this purpose, we employed and studied the performance of haptics over Internet protocol (HoIP) in order to examine its feasibility to ensure a reliable communication over 5G NR in terms of bit rate and E2E delay. We show through numerical analysis and simulations that HolP overhead will not violate the Quality of Service (QoS) requirements. It is proved that, in case of single user scenario and very low SINR, the radio link still support the required data rate and E2E delay.
