Future 5G mobile communication systems are expected to integrate different radio access technologies including the satellite component. Within the 5G framework, the terrestrial services can be augmented with the development of High Throughput Satellite (HTS) systems and new mega constellations meeting 5G requirements, such as high bandwidth, low latency, increased coverage, including rural areas, air, and seas. This paper provides an overview of the current 5G initiatives and projects followed by a proposed architecture for 5G satellite networks where the SDN/NFV approach facilitates the integration with the 5G terrestrial system. In addition, a novel technique based on network coding is analyzed for the joint exploitation of multiple paths in such integrated satelliteterrestrial system. For TCP-based applications, an analytical model is presented to achieve an optimal traffic split between terrestrial and satellite paths and optimal redundancy levels.

This paper is not a survey related to generic wireless sensor networks (WSNs), which have been largely treated in a number of survey papers addressing more focused issues; rather, it specifically addresses architectural aspects related to WSNs in some way connected with a satellite link, a topic that presents challenging interworking aspects. The main objective is to provide an overview of the potential role of a satellite segment in future WSNs. In this perspective, requirements of the most meaningful WSN applications have been drawn and matched to characteristics of various satellite/space systems in order to identify suitable integrated configurations.

Traditional centralised data storage and processing solutions manifest limitations with regards to overall operational cost and the security and auditability of data. One of the biggest issues with existing solutions is the difficulty of keeping track of who has had access to the data and how the data may have changed over its lifetime; while providing a secure and easyto-use mechanism to share the data between different users. The ability to electronically regulate data sharing within and across different organisational entities in the supply-chain (SC), is an open issue, that is only addressed partially by existing legal and regulatory compliance frameworks. In this work, we present Cydon, a decentralised data management platform that executes bespoke distributed applications utilising a novel search and retrieve algorithm leveraging metadata attributes. Cydon utilises a smart distributed ledger to offer an immutable audit trail and transaction history for all different levels of data access and modification within a SC and for all data flows within the environment. Results suggest that Cydon provides authorised and fast access to secure distributed data, avoids single points of failure by securely distributing encrypted data across different nodes while maintains an "always-on" chain of custody.
