Software Defined Internet of Things using lightweight protocol

Abstract

Abstract The upsurge in the Internet of Things (IoT) has led towards an increasing interest in simplifying the control mechanism in the wireless network. The control mechanism is a challenge as it involves data acquisition and analysis, decision making, and actuation/control in IoT networks. This has led towards combining Software Defined Networks (SDN) and IoT for easy of controlling the network devices. The mobile application available at the tip of hands to control the connected devices to the internet has led to exponential growth in data. The management and handling the data intensive applications is a challenge to the network operators. SDN is a paradigm shift that enables network programmability, control, and management of diverse networking devices. This paper describes the data transmission in SDN and integration of SDN and IoT. The light weight protocol Message Queue Telemetry Transport (MQTT) is used for data transmission between the IoT devices. The result analysis shows that the light weight protocol MQTT is 30% efficient for data transmission in SDN IoT architecture. The testbed for integrating virtual network in SDN and real-time network for IoT applications using lightweight protocol is described.
