IoT service in home domain needs common and effective ways to manage various appliances and devices. So, the home environment needs a gateway that provides dynamical device registration and discovery. In this paper, we propose the IoT Home Gateway that supports abstracted device data to remove heterogeneity, device discovery by DPWS, Auto-configuration for constrained devices such as Arduino. Also,...
The wireless communication capability of sensors and actuators made them suitable for several automation solutions which involve sensing physical properties and acting upon them. These days, gateway or cloud based sensor/actuator interaction models are widely used. In this model, every sensor/actuator interaction goes through the gateway or via the cloud. In order to realize the true Internet of Things...
In Wireless Sensors and Actuators Networks (WSANs), actuator nodes are nodes richer in resources (processing capacity, power transmission and energy storage) and better suited than sensor nodes to process the data, make decisions based on sensed values and perform appropriate actions. In addition, in order to provide timely action, coordination between sensors and actuators is necessary. Thus, in...
SCADA (supervisory control and data acquisition) systems control and monitor industrial and critical infrastructure functions, such as the electricity, gas, water, waste, railway and traffic. Recent attacks on SCADA systems highlight the need of a SCADA security testbed, which can be used to model real SCADA systems and study the effects of attacks on them. We propose the architecture of a modular...
