Issues and Challenges Facing Low Latency in the Tactile Internet

The Tactile Internet (TI) has given rise to a wide range of use cases with diverse type of applications. In view of the aforementioned factors impacting the delay of haptic applications, in this chapter describes the latest research works making use of different technologies to find a solution for guaranteeing the end‐to‐end (E2E) delay. The TI is in its infancy and new methods should be developed to guarantee the low‐latency criteria that are one of the essentials among the others characterized by ultra‐reliability, security and high Quality of Service and Quality of Experience guarantee. The main layers involved in resource allocation, and which would impact on the E2E latency in the protocol stack, are the physical and medium access control layers. The Mobile edge computing plays a very important role in the reduction of low latency and it is designed for this purpose.
