IEEE802.15.6 is a radio interface standard for wireless connectivity of wearable and implantable sensors and actuators located inside or in close proximity to the human body i.e., Body Area Network (BAN). Medical applications impose stringent requirements on BAN Quality of Service (QoS), including reliability and on-time availability of the sensors data. However, interference from other co-located BANs or other nearby devices sharing the same spectrum may cause unacceptable QoS degradation. The impact of such degradations can be minimized by using adaptive schemes that intelligently adjust relevant parameters at the transmitting or receiving nodes of a BAN. This paper provides a framework for low complexity regret minimization based algorithms for Energy Detection Threshold (EDT) adaptation in the transmitter node of a BAN. The nodes are assumed to be using the Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) protocol according to the IEEE 802.15.6 BAN standard. Our preliminary simulation results demonstrate the performance gain of our algorithm compared to using a fixed EDT, and thus warrant future efforts in the adaptive EDT optimization as a mechanism to maintain QoS in various interference scenarios.
IEEE802.15.6是一种无线接口标准，用于位于人体内部或靠近人体的可穿戴和可植入传感器和执行器的无线连接，即人体区域网络(BAN)。医疗应用对BAN服务质量(QoS)提出了严格的要求，包括传感器数据的可靠性和准时可用性。但是，来自其他同址ban或共享同一频谱的其他附近设备的干扰可能导致不可接受的QoS退化。通过在BAN的发送或接收节点上使用智能调整相关参数的自适应方案，可以将这种退化的影响降至最低。本文提出了一种基于能量检测阈值(EDT)自适应的低复杂度后悔最小化算法框架。假设节点使用符合IEEE 802.15.6 BAN标准的CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance)协议。我们的初步模拟结果表明，与使用固定EDT相比，我们的算法获得了性能增益，因此保证了自适应EDT优化作为在各种干扰情况下保持QoS的机制的未来努力。

Smart boards are triggering the IoT revolution, allowing to make common objects and things smart through their network, storage and processing capabilities. Arduino boards have a prominent role in this revolution, due to their customizability and programming freedom. From a different perspective, another strategic development for the IoT is towards Cloud, allowing to properly manage things and data ubiquitously, on demand, as services. Pushing in this direction, we can pave the way to the Cloud of Things, where real things, rather than the data they produce, can be provided to third parties, by adopting a “device-centric” approach. To this purpose, virtualization of physical resources becomes an essential step and core mechanism. In this paper we focus on smart board virtualization, implementing a flexible solution for Arduino boards based on Stack4Things, allowing to create, multiplex, migrate and deploy virtual boards in IoT-Cloud contexts. The results obtained by a preliminary implementation and experiments on the #SmartME testbed are shown in the paper to demonstrate the feasibility and the effectiveness of the proposed solution.

Energy performance of commercial buildings heavily relies on three interrelated groups of factors: Business processes, facility characteristics & occupant behaviour under specific context. We are presenting an innovative framework developed in the EU H2020 OrbEEt project that aims to establish a holistic organizational energy performance framework extending contemporary and standardized energy performance rating practices by incorporating dynamic business and behavioural information. The proposed EPC framework is tested and evaluated in four pilot buildings around Europe, addressing different social, business and operational characteristics.

Device localization is a common issue on connected objects and persons. Relative localization is a particular case where one don't care about an absolute position, but about knowing how far and in which direction an object is from a reference point in an approximate manner. This work makes part of a larger project which aims to track groups of children for preventing hazards. In this paper we present a relative localization system in the form of a distributed multi-hop routing algorithm deployed on a set of wearable Bluetooth Low Energy devices. This paper introduces the distributive algorithm, describes its implementation, and presents performance results which permit to validate the approach and identify the system limitations.

The rapidly increasing number of intelligent, cloud-connected things that are embedded in our daily lives raises legitimate concerns about the privacy costs paid for the benefits these technologies provide. In this paper, we argue that this is a false choice, and motivate and describe a technology that enables citizens to effectively and conveniently monitor data collected about them. Our overarching goal is to expand awareness of the need to move from the current state of consumer ignorance or apprehensive trust to an era of data collection transparency (DCT), where consumers understand the data that is collected about them and make informed decisions based on that understanding. We show that DCT can be achieved with a suite of technologies built around recent developments in secure elements, as well as a virtual token methodology with public keys using addressable cryptographic tables.

This paper presents the research objectives of the enCOMPASS project, which aims at implementing and validating an integrated socio-technical approach to behavioural change for energy saving. To this end, innovative user-friendly digital tools will be developed to 1) make energy data consumption available and understandable for different types of users and stakeholders (household residents, office employees, school pupils, building managers, utilities, ICT providers) and to 2) empower them to collaborate in order to achieve energy savings and manage their energy needs in efficient, cost-effective and comfort-preserving ways. The project will demonstrate how this can be achieved with a novel approach that integrates user-centered visualisation of energy data from smart sensors and user-generated information with context-aware collaborative recommendations for energy saving, intelligent control and adaptive gamified incentives enabling effective and sustained behavioural change.

Time-Slotted Channel Hopping (TSCH) from the IEEE 802.15.4-2015 standard uses channel hopping to combat interference and frequency-selective fading. Due to the pseudorandom nature of TSCH standard channel hopping process, the energy usage and end-to-end delay achieved in statically configured TSCH networks are suboptimal when compared to using a dynamically updated set of channels. We investigate and compare the advantages of several different adaptive channel selection metrics and methods under the presence of external, frequency-specific interference. In our experiments, PRR-based channel quality assessment with downstream-driven channel selection shows the best results. It is able to reliably distinguish between heavily-interfered and lightly-interfered channels, reduces the number of packet retransmissions up to 2.7 times, achieves up to 22 % lower average radio-on time, and shows close-to 100 % PDR even under heavy interference.

Context-awareness in IoT applications is an emerging research field with profound impact on smartness, relevance, adaptability, dependability and flexibility of such applications. Relatively few substantial R&D projects have been carried out on how IoT-scale context can be stored, indexed, retrieved and provisioned to various IoT services. This paper addresses the challenge of building IoT context storage management system (CSMS) as a core component of Context-as-a-Service (CoaaS) platform which is a major focus of IoT-EPI project bIoTope. Motivation and conceptual architecture of context storage management system are presented and discussed. Elements of the reference architecture are also proposed. The paper concludes with highlighting the urgent need for developing CSMS and ways for architecting and implementing it.
