Demo abstract: Assessing the impact of fog and cloud computing on an IoT service running over an optical/wireless network-An experimental approach

In this demonstration, we explore the impact of optical-wireless network infrastructure when we vary the locus of computing for Internet of Things (IoT) services. Those services could involve devices ranging from low complexity sensors and actuators (e.g., smart light bulbs) to more advanced ones (e.g., multimedia sensors and smart glasses); in our experiment, we focus on the former. We design a smart light system that allows the control of light bulbs (on/off, color, brightness) through voice and sign language. We vary the location at which the command processing (voice or sign recognition) takes place - locally or in the cloud - and assess its impact on the latency in the response to the command.
