Currently, gadgets are the most common and frequent ways of acquiring digital services. However, due to recent advancements in smart sensing and communication technologies, it seems that, this trend might get change in coming days. Future is hinting us towards a gadget-free hyperconnected society, where each object can sense, gather and process the information and can able to take context based decisions. The vision behind this novel concept is to provide users, digital services anywhere and anytime, without using explicit gadgets or even wearables. Smart surrounding will be able to provide digital services to users, as per their requirements. Also with the addition of 5G technology, this vision will be more strengthen and thus novel services will come into action. This will generate massive amount of critical data and eventually dealing with privacy in such ambient environment will be one of the major concerns for users. There, this paper presents privacy challenges from user's perspectives, which can potentially arise in such gadget-free environment. A conceptual privacy framework is also discussed in the light of the user privacy issues. Furthermore, we provide an overview of transformation requirements needed in transition from the gadget to gadget-free world.

The objective of this paper is to illustrate how to monetize infrastructures and services. This is achieved by a combination of measuring consumption, applying pricing strategies and client invoicing. Furthermore, a range of billing solutions are available in order to cover the Rating, Charging and Billing process. The focus here is on the comparison of solution based suitability, which depends on complexity of records and volume of transactions. RCB Cyclops, as an open source solution, is presented and evaluated in terms of data throughputs focusing on doubling host machines and yielding 70-80% boost in performance.

This paper provides a view to Peer-to-Peer (P2P) approach for smart grid operation adopted in P2P-SmarTest project. It provides an overview on solutions proposed for distributed P2P energy trading, P2P grid control and wireless communication enabling the proposed P2P operation. The paper proposes some business models that can be adopted in a P2P setting. We also outline the barriers and enablers against and for adopting local or regional P2P based electricity operations.

The development of 5G networks supposes a big challenge for mobile operators in order to satisfy the ambitious objective of delivering broadband services ubiquitously. Based on this, the increasing capabilities of satellite systems have created the consensus that such systems can satisfy the required necessities for several scenarios, such as for rural or low-density populated areas. Used in combination with a terrestrial wireless backhaul, satellite backhauls are envisaged as a solution to improve the network efficiency in terms of delivered traffic to access nodes while increasing its resiliency for the mentioned scenarios. This paper presents i) our ns-3 framework for modeling hybrid terrestrial-satellite mesh backhaul networks that carry LTE traffic and ii) a comparison of our different backpressure-based approaches against generic shortest-path routing in a low-density suburban scenario for LTE networks. Simulation results reveal the advantages of backpressure-based approaches to make an efficient use of the network resources while integrating seamlessly both terrestrial and satellite backhaul resources.
