Intelligent and Dynamic Wi-Fi Bond Interface Selection using Software Defined Networking

M. Dilmore, A. Doufexi, G. Oikonomou

Abstract:
This paper investigates predictive, dynamic bond interface selection using Software Defined Networking in large-scale, highly-loaded Wi-Fi networks. A novel, MatLab-based framework for Wi-Fi interface bonding at the Link Layer is presented utilising existing single-interface analysis by Bianchi and Chatzimisios, and used to evaluate the throughout performance of the current, static selection approach of implementations such as Linux Bonding. A predictive, centralised, SDN-assisted algorithm for bond interface selection is presented and evaluated, and shown to improve overall bonding efficiency by up to 11.25%. Control plane latency analysis suggests careful management of configuration updates is required when link delay is high.
