. Energy Efficiency In Sdn-Based Iot Networks: A Review

Abstract

The Internet of Things (IoT) is a new paradigm that intends to connect all intelligent physical things to the internet so that they can work together to offer intelligent services to users. Some of the IoT applications include smart retail, smart cities, smart metering, smart grids, smart wearables, etc. Since IoT devices are growing explosively in number and are characterised by resource constraints and heterogeneity, managing IoT systems has become a problem. Software Defined Networking (SDN) is a new paradigm deployed in IoT networks as a management solution for achieving agile, flexible, and sustainable IoT systems. Energy is a major concern in SDN-based IoT networks since IoT devices are resource-constrained. This review examined the state-of-the-art contributions on energy efficiency in SDN-based IoT networks, the gap, and proposes future research directions.
