Abstract: The devices running embedded applications tend to be battery-powered, and the energy efficiency of their operations is an important enabler for the wide adoption of the Internet-of-Things. Optimization of energy usage depends on modelling power consumption. A model-based simulation must consider parameters that depend on the device used, the operating system, and the distributed application under study. A realistic simulation thus depends on knowledge regarding how and when devices consume energy. This paper presents an approach to direct measurement of energy consumed in the different execution states of the device. We present the architecture and the measurement process that were implemented. We provide a reference architecture, whose constituent parts can be implemented in different manners, e.g. the processing unit of the device can be the chip on a mote, or an Field- Programmable Gate Array (FPGA) implementation. Details are given regarding the setup of the experimental tests, and a discussion of the results hints at which architecture is the best for each application under study. The presented methodology can be extended easily to new architectures and applications, to streamline the process of building realistic models of power consumption.

Abstract: 6 Gbps transmission over a very low-power multi Radio Access air-interface for indoor is demonstrated. A single-mode fiber based fronthaul architecture is employed together with plastic optical fiber in indoor small-cells. The low power transmission coverage is similar to the classic femtocell coverage and is suitable for most 5G indoor scenarios.

Abstract: Mobile applications will be a dominant element in the 5G domain. Ensuring the correct and efficient behaviour of the applications and devices on which they run becomes a critical factor to ensure the mobile communications market meets the expectations of final users. The EU project TRIANGLE is building a framework to help app developers and device manufacturers in the evolving 5Gsector to test and benchmark new mobile applications, devices, and services utilizing existing and extended FIRE testbeds. This innovative framework will facilitate the evaluation of the Quality of Experience and enable certification for new mobile applications and devices.

Abstract: Transport IP/optical networks are evolving in capacity and dynamicity of configuration. This evolution gives little to no attention to the specific needs of applications, beyond increasing raw capacity. TheACINO concept is based on allowing applications to explicitly specify requirements for requested services in terms of high-level (technology- and configuration-agnostic) requirements such as maximum latency or reliability. These requirements are described using intents and certain primitives which facilitate translation to technology specific configuration within the ACINO infrastructure. To support this application centric approach, SDN has a key role in this evolution. There are representative use cases where SDN gives an added value when considering not only the network but also the application layer.

Keywords: Application-Centric, IP-Optical, Multi-layer.
