“…Previous studies [16], [17], [18], [19] have shown that edge computing enables advanced VR Six Degrees of Freedom (6DoF) experiences by supporting the deployment of computeintensive services. Chakareski et al [16] investigate edgebased 6DoF VR streaming over millimeter-Wave to offer high available spectrum and data rates for VR HMDs.

“…It has been pointed out that an E2E latency of more than 5 ms for advanced VR applications would lead to cybersickness [4], [5]. To put this challenge in perspective, a display running at 60 Hz, 90 Hz, and 120 Hz is updated every 16.67 ms, 11.11 ms, and 8.33 ms, respectively [6]. Even considering that extreme communication requirements, e.g., latency and throughput, will be achieved by 6G networks, the constrained computation and energy impose restrictions on processing 6DoF content on VR HMDs [7].…”

The next generation of Virtual Reality (VR) applications is expected to provide advanced experiences through Six Degrees of Freedom (6DoF) content, which requires higher data rates and ultra-low latency. In this article, we refactor 6DoF VR applications into atomic services to increase the computing capacity of VR systems aiming to reduce the end-to-end (E2E) of 6DoF VR applications. Those services are chained and deployed across Head-Mounted Displays (HMDs) and Multi-access Edge Computing (MEC) servers in high mobility scenarios over realedge network topologies. We investigate the Distributed Service Chain Problem (DSCP) to find the optimal service placement of services from a service chain such that its E2E latency does not exceed 5 ms. The DSCP problem is N P-hard. We provide an integer linear program to model the system, along with a heuristic, namely disTributed sErvice chaiN orchEstraTor (TENET), which is one order of magnitude faster than optimally solving the DSCP problem. We compare TENET to DSCP implementation and well-known service migration algorithms in terms of E2E latency, power consumption, video resolution selection based on E2E latency, context migrations, and execution time. We observe a significant reduction of E2E latency and gains in more advanced video resolution selection and accepted context service migrations when using TENET's deployment strategy on VR services.
