Situational-Context: A Unified View of Everything Involved at a Particular Situation

As the interest in the Web of Things increases, specially for the general population, the barriers to entry for the use of these technologies should decrease. Current applications can be developed to adapt their behaviour to predefined conditions and users preferences, facilitating their use. In the future,Web of Things software should be able to automatically adjust its behaviour to non-predefined preferences or context of its users. In this vision paper we define the Situational-Context as the combination of the virtual profiles of the entities (things or people) that concur at a particular place and time. The computation of the Situational-Context allow us to predict the expected system behaviour and the required interaction between devices to meet the entities’ goals, achieving a better adjustment of the system to variable contexts.Universidad de Málaga.

Implementation of context-aware network architecture for smart objects based on functional composition

Lack of flexibility of current Internet architecture led researchers to come up with new paradigms for a novel Internet architecture, which would be able to reduce complexity and increase flexibility compared to current Internet architecture. Functional co mposition is a promising approach to flexible and evolvable architecture design. The idea is composing complex protocol suites by dynamically bind and arrange different functions to obtain certain behavior. Herein, we present the implementation of a contex t - aware network architecture based on functional composition for smart objects. A sub - set of those basic functional blocks has been implemented and validated on an experimental testbed using different network topologies .Peer ReviewedPostprint (author’s final draft

Technology assessment of advanced automation for space missions

Six general classes of technology requirements derived during the mission definition phase of the study were identified as having maximum importance and urgency, including autonomous world model based information systems, learning and hypothesis formation, natural language and other man-machine communication, space manufacturing, teleoperators and robot systems, and computer science and technology

Pregovaranje u Internetu stvari

Internet of things as a market, and the number of connected devices in particular is growing very rapidly. Currently, application owners deploy new devices for each application that needs the data. As the number of sensors increases, it will become much more practical to reuse existing sensors for new applications than to deploy new ones. But the problem is that the application owner needs to agree with device owners on conditions under which will the data be made available to applications. Doing this manually is very expensive both in terms of money and time. We implemented a system that does this automatically using negotiating agents. The system was tested on simulated environments and showed that it can mediate between devices and applications with reasonable performance.Internet stvari kao tržište, a posebno broj spojenih uređaja, raste vrlo brzo. Danas vlasnici aplikacija postavljaju nove uređaje za svaku aplikaciju kojoj su potrebni podatci. Kako se povećava broj senzora u upotrebi, postaje sve praktičnije koristiti postojeće senzore nego postavljati nove. Problem predstavlja činjenica da se vlasnik aplikacije mora dogovoriti s vlasnicima uređaja o uvjetima pod kojima će aplikacijama biti dozvoljeno dohvaćanje izmjerenih vrijednosti. Pojedinačno je dogovaranje između vlasnika za svaki uređaj skupo i sporo. Izgradili smo sustav koji automatizira ovaj proces pomoću programskih agenata koji pregovaraju. Sustav je ispitan na simuliranom okruženju i pokazuje da može posredovati između uređaja i aplikacija s razumnim performansama
