Load balancing mathematical model in SDN-based wireless technologies

Abstract

In this study, we propose to update the formerly known flow-based load balancing model in the presence of heterogeneous topologies in communication networks (CN). It was further emphasized that the proposed approach could be used in SDN-based wireless technologies. To reduce network and data traffic load, the model changes the optimality criteria of route alternatives. Optimization focuses on re-evaluating the optimality criteria of a routing solution. As an alternative, a linear- quadratic criterion was proposed to minimize the maximum utilization of network links. As a result, the CN load balancing process has been improved to optimize the end-to-end average packet delay as much as possible, which is a critical Quality of Service (QoS) parameter in networks.
