Framework for Reprogrammable In-network Processing in complex IoT systems

With the advent of numerous Internet of things(IoT) applications, the number of IoT devices increased drastically and we are moving towards Smart Home which utilizes these heterogeneous IoT devices to accomplish a task with less user intervention. On the other hand, making these IoT devices interact with each other and performing some processing on data gathered from different IoT devices, without using cloud services is a huge technical challenge because we need to be completely aware of underlying heterogeneous IoT topology and develop a standardized way to make them interact. Moreover cloud services are expensive and making it localized will enhance the feasibility to use different communication mechanisms. In order to take full advantage of these combined IoT services we propose a local, centralized IoT framework which will provide a standard to perform in-network processing and dynamically forward packets based on different IoT application requirements. We introduce SDN-inspired architectural model in complex IoT systems to have fine-grained control over the architecture. In this paper, we will discuss on evaluating the feasibility of using SDN architecture for in-network processing in complex IoT systems. Keywords—IoT, SDN, Open-vSwitch, LLDP.
