As the networking infrastructure and its components evolve within the telecommunications ecosystem, future networks will be able to accommodate services and applications of the upcoming 5G Tactile Internet. After analysing and experimenting with 5G enablers, this thesis focuses on haptic communication over the future communication systems. More specifically, the thesis addresses the issues related to Quality of Service (QoS) provisioning for Ultra Reliable Low Latency Communication (URLLC) traffic and specifically for bilateral teleoperation applications. Assuming a dynamic priority queuing system serving URLLC traffic as high priority, under certain conditions, prioritisation causes resource starvation for trac of lower priority. On the other hand, without guaranteed QoS, bilateral teleoperation system performance and operation can be negatively affected, especially in the presence of delay. In this thesis, the aforementioned problem is addressed by proposing a novel framework that focuses on minimising the impact of delay on haptic communication while also minimising the effect of QoS overprovisioning. It also presents a possible 5G architecture design and suggests necessary architectural design components that enable the Tactile Internet. Simulation results verify that it is feasible to manage the balance of increasing teleoperation performance of high priority traffic and decreasing the impact of resource starvation of low priority traffic.
