Distributed System based on Cloud Computing with Wireless Sensor Networks

The main aim of this work is to provide an architectural approach based on interoperable technology for communicating the Wireless Sensor Network (WSN) entities with end users using the Cloud Computing concept. Referring to the comparative survey carried out between Java RMI, CORBA and Web services, we opted for CORBA as middleware to interconnect the various components of our distributed system; this choice is mainly based on criteria of the performances and the integration possibility with different programming language. In this architecture, we also propose real-time monitoring services, data archiving, notification and other useful services to communicate with the Wireless Sensor Network in both directions

SMArc: a proposal for a smart, semantic middleware architecture focused on Smart City energy management

Among the main features that are intended to become part of what can be expected from the Smart City, one of them should be an improved energy management system, in order to benefit from a healthier relation with the environment, minimize energy expenses, and offer dynamic market opportunities. A Smart Grid seems like a very suitable infrastructure for this objective, as it guarantees a two-way information flow that will provide the means for energy management enhancement. However, to obtain all the required information, another entity must care about all the devices required to gather the data. What is more, this entity must consider the lifespan of the devices within the Smart Grid—when they are turned on and off or when new appliances are added—along with the services that devices are able to provide. This paper puts forward SMArc—an acronym for semantic middleware architecture—as a middleware proposal for the Smart Grid, so as to process the collected data and use it to insulate applications from the complexity of the metering facilities and guarantee that any change that may happen at these lower levels will be updated for future actions in the system
