MobileTrust: Secure Knowledge Integration in VANETs

Vehicular Ad hoc NETworks (VANET) are becoming popular due to the emergence of the Internet of Things and ambient intelligence applications. In such networks, secure resource sharing functionality is accomplished by incorporating trust schemes. Current solutions adopt peer-to-peer technologies that can cover the large operational area. However, these systems fail to capture some inherent properties of VANETs, such as fast and ephemeral interaction, making robust trust evaluation of crowdsourcing challenges. In this ar

IDEAL-CITIES – A Trustworthy and Sustainable Framework for Circular Smart Cities

IDEAL-CITIES – A Trustworthy and Sustainable Framework for Circular Smart Cities

Reflecting upon the sustainability challenges cities will be facing in the near future and the recent technological developments allowing cities to become “smart”, we introduce IDEAL-CITIES; a framework aiming to provide an architecture for cyber-physical systems to deliver a data-driven Circular Economy model in a city context. In the IDEAL-CITIES ecosystem, the city’s finite resources, as well as citizens, will form the pool of intelligent assets in order to contribute to high utilization through crowdsourcing and real-time decision making and planning. Wedescribetwousecasesas a vehicle to demonstrate how a smart city can serve the Circular Economy paradigm.

Blockchain-enabled Intelligent Asset Exchange for a Circular Economy

Blockchain-enabled Intelligent Asset Exchange for a Circular Economy

As the notion of circular economy gains momentum, intelligent assets increasingly form the backbone of sustainable ecosystems. Althoughtheseassetscansupply the necessary knowledge for fueling the value drivers of a circular economy, the generated value will be significantly amplified by allowing third parties to manage them and profit from better asset utilization. However, for a never-changing networked environment consisting of numerous assets, ownership needs to be dynamic, granular, and adaptable in order to maximize gains. Blockchain-based mechanisms can effectively serve this need b enabling transfer of asset ownership directly between parties participating in the circular economy while introducing trust, efficiency, and automation in asset exchange contracts.
