Multiple threats have been identified when citizens interact with online services such as unknown provenance of information, unknown quality of service providers, spread of fake news, fraud, personal privacy violation, centralisation of power to name a few. Blockchain has been considered as key technology to address many of these challenges; however, in reality, building trustworthy decentralized applications (Dapps) is not straightforward as much blockchain-based functionality needs to be developed from scratch and combined with data semantics. In this paper, we propose a new software framework, namely ONTOCHAIN, that leverages semantic web and blockchain technology to build, as distinct value for the Next Generation Internet, fundamental support for trustworthy data/services exchange and trustworthy content handling. It comprises a novel protocol suite grouped into high-level application protocols, such as data provenance, reputation models, decentralised oracles, market mechanisms, ontology representation and management, privacy aware and secure data exchange, multi-source identity verification, value sharing and incentives, and lower-level core protocols that include authorisation, certification, privacy-aware data processing, cross-chain gateways, identity management, secure data exchange, and data semantics in smart contracts. We demonstrate that these protocols are already available and combined to implement interesting NGI Dapps.

Τα Ασύρματα Πλεγματικά Δίκτυα αποτελούν πλέον τεχνολογία κλειδί για τα ασύρματα δίκτυα επόμενης γενιάς. Το IEEE 802.11s Standard ορίζει τον τρόπο που οι ασύρματοι κόμβοι συνδέονται μεταξύ τους ώστε να δημιουργηθεί ένα WLAN πλεγματικό δίκτυο. Επίσης, ορίζει το πρωτόκολλο δρομολόγησης και τη μετρική που χρησιμοποιεί ένα 802.11s πλεγματικό δίκτυο για τη διαδικασία της δρομολόγησης. Η κατανάλωση της ενέργειας των πλεγματικών κόμβων αποτελεί ένα σημαντικό παράγοντα στη βιωσιμότητα του πλεγματικού δικτύου. Η χρήση αλγορίθμων δρομολόγησης που λαμβάνουν υπόψη τους την ενέργεια μπορεί να παρατείνει τη διάρκεια ζωής του δικτύου. Σε αυτή την έρευνα υλοποιήθηκε μία νέα μετρική για τα 802.11s Πλεγματικά Δίκτυα που λαμβάνει υπόψη της τη διαθέσιμη ενέργεια των πλεγματικών κόμβων. Για την αξιολόγηση της προαναφερθείσας μετρικής σε σύγκριση με την πρότυπη μετρική του IEEE 802.11s Standard (airtime link metric) χρησιμοποιήθηκε ο ns3. Wireless Mesh Networks are the key technology for the next generation wireless networks. The IEEE 802.11s Standard defines the procedures that wireless nodes follow in order to interconnect and create a WLAN mesh network. It, also, defines the routing protocol and the metric that are used by a IEEE 802.11s mesh network to route data. The energy consumption of mesh nodes affects the lifetime of a mesh network. By introducing energy - aware routing algorithms, the lifetime of the network may be prolonged. In this research, a new energy - aware metric for the IEEE 802.11s mesh networks have been implemented. The ns3 simulator was used for the evaluation of the aforementioned metric and the default metric used by IEEE 802.11s Standard.
