The forthcoming sixth generation (6G) network technology will trigger tremendous changes across several application scenarios and even in the way we work, communicate and, more in general, organize our everyday life. In particular, in such a new digital era, Virtual Reality (VR) technology will play a fundamental role, carrying with it numerous challenges as regards the increasing demand of high rate, high reliable and low latency communications, especially in reference to internet of things environments. In this sense, an effective end-to-end delay analysis becomes imperative to pursue an efficient design of the foreseen VR services. Towards this goal, this paper proposes the end-to-end delay investigation through the martingale theoretical bound and considering the stochastic network calculus principles for its formulation. The performance discussion focuses on the achieved communications reliability, comparing the analytical predictions obtained via the martingale bound with the simulation results, and the Markov queuing theory based alternative. The presented results confirm the validity of the proposed approach, exhibiting noticeable closeness between the theoretical bound and the simulation outcomes.
