Game Theory-based Routing for Software-Defined Networks
Amit Nayyer · International Journal for Research in Applied Science and Engineering Technology · 2020
Software Defined Networking is an emerging paradigm that allows the separation of the control plane from the forwarding plane.This shift in paradigm towards plane separation provides various advantages as compared to the traditional networks.Routing is one such benefit that allows more controlled, predicted, and dynamic routing in the network due to its centralized paradigm.The global network view is available at the controller.It can take optimal decisions compared to distributed systems where a global network view is impossible to create, as many message exchanges are required.Dynamic routing is one of the notions where the decisions are made in real-time by viewing traffic in the network.Inspecting the current traffic, an optimal path is chosen.This practice of selecting an optimal route is possible in different ways.Game theory is a model for strategic decision-makers applied in another field to make the results more effective.In this paper, the game theory for traffic light control is studied in detail, and the mechanism is applied for efficient routing in the network.Simulation results show improvement over traditional methods of routing.
