Abstract
Future tactile internet is likely to have a combination of underlying wired and wireless networks with heterogeneous (legacy and new) access technologies to support diverse applications, e.g., Internet of Things (IoT). In this context, Opportunistic Network (ON) can be an important paradigm in wireless networks to help augment capacity of network for varying internet traffic requirements. Software Defined Networking (SDN), with its logically centralized control plane, is expected to ease implementation of functions, such as radio resource management, across wireless networks with multiple Radio Access Technologies (multi-RAT). Hence, tactile internet is likely to work over an intelligent SDN controlled cloud-based implementation of wired and wireless technologies, and necessitating opportunistic network capacity augmentation with appropriate RAT. This paper presents a novel SDN assisted architecture for futuristic wireless networks which augments network capacity on need basis using unsupervised Machine Learning (ML) to create ON cells with appropriate RAT. Subsequently, we define utilities for the Wireless Network Infrastructure (WNI) and the User Equipment (UE) to evaluate the benefit of creation of ON cells. A game theoretic model is developed to understand the strategies of the two players, i.e., WNI and UE, while using the ON cell resources. The Nash Equilibria (NE) of the game reveal that both UE and WNI gain by co-operating with each other and lose otherwise in utilizing the augmented network capacity. Simulation results also confirm this observation.
