Major requirements for building Smart Homes in Smart Cities based on Internet of Things technologies

The recent boom in the Internet of Things (IoT) will turn Smart Cities and Smart Homes (SH) from hype to reality. SH is the major building block for Smart Cities and have long been a dream for decades, hobbyists in the late 1970s made Home Automation (HA) possible when personal computers started invading home spaces. While SH can share most of the IoT technologies, there are unique characteristics that make SH special. From the result of a recent research survey on SH and IoT technologies, this paper defines the major requirements for building SH. Seven unique requirement recommendations are defined and classified according to the specific quality of the SH building blocks

Digital Rights Management and Consumer Acceptability: A Multi-Disciplinary Discussion of Consumer Concerns and Expectations

The INDICARE project – the Informed Dialogue about Consumer Acceptability of DRM Solutions in Europe – has been set up to raise awareness about consumer and user issues of Digital Rights Management (DRM) solutions. One of the main goals of the INDICARE project is to contribute to the consensus-building among multiple players with heterogeneous interests in the digital environment. To promote this process and to contribute to the creation of a common level of understanding is the aim of the present report. It provides an overview of consumer concerns and expectations regarding DRMs, and discusses the findings from a social, legal, technical and business perspective. A general overview of the existing EC initiatives shows that questions of consumer acceptability of DRM have only recently begun to draw wider attention. A review of the relevant statements, studies and reports confirms that awareness of consumer concerns is still at a low level. Five major categories of concerns have been distinguished so far: (1) fair conditions of use and access to digital content, (2) privacy, (3) interoperability, (4) transparency and (5) various aspects of consumer friendliness. From the legal point of view, many of the identified issues go beyond the scope of copyright law, i.e. the field of law where DRM was traditionally discussed. Often they are a matter of general or sector-specific consumer protection law. Furthermore, it is still unclear to what extent technology and an appropriate design of technical solutions can provide an answer to some of the concerns of consumers. One goal of the technical chapter was exactly to highlight some of these technical possibilities. Finally, it is shown that consumer acceptability of DRM is important for the economic success of different business models based on DRM. Fair and responsive DRM design can be a profitable strategy, however DRM-free alternatives do exist too.Digital Rights Management; consumers; Intellectual property; business models

A Link-Layer Virtual Networking Solution for Cloud-Native Network Function Virtualisation Ecosystems: L2S-M

Microservices have become promising candidates for the deployment of network and vertical functions in the fifth generation of mobile networks. However, microservice platforms like Kubernetes use a flat networking approach towards the connectivity of virtualised workloads, which prevents the deployment of network functions on isolated network segments (for example, the components of an IP Telephony system or a content distribution network). This paper presents L2S-M, a solution that enables the connectivity of Kubernetes microservices over isolated link-layer virtual networks, regardless of the compute nodes where workloads are actually deployed. L2S-M uses software-defined networking (SDN) to fulfil this purpose. Furthermore, the L2S-M design is flexible to support the connectivity of Kubernetes workloads across different Kubernetes clusters. We validate the functional behaviour of our solution in a moderately complex Smart Campus scenario, where L2S-M is used to deploy a content distribution network, showing its potential for the deployment of network services in distributed and heterogeneous environments.This article has partially been supported by the H2020 FISHY Project (Grant agreement ID: 952644) and by the TRUE5G project (PID2019-108713RB681) funded by the Spanish National Research Agency (MCIN/AEI/10.13039/5011000110)

A survey of self organisation in future cellular networks

This article surveys the literature over the period of the last decade on the emerging field of self organisation as applied to wireless cellular communication networks. Self organisation has been extensively studied and applied in adhoc networks, wireless sensor networks and autonomic computer networks; however in the context of wireless cellular networks, this is the first attempt to put in perspective the various efforts in form of a tutorial/survey. We provide a comprehensive survey of the existing literature, projects and standards in self organising cellular networks. Additionally, we also aim to present a clear understanding of this active research area, identifying a clear taxonomy and guidelines for design of self organising mechanisms. We compare strength and weakness of existing solutions and highlight the key research areas for further development. This paper serves as a guide and a starting point for anyone willing to delve into research on self organisation in wireless cellular communication networks

Rights and services interoperability for multimedia content management

The main goal of the work presented in this thesis is to describe the definition of interoperability mechanisms between rights expression languages and policy languages. Starting from languages interoperability, the intention is to go a step further and define how services for multimedia content management can interoperate by means of service-oriented generic and standardised architectures. In order to achieve this goal, several standards and existing initiatives will be analysed and taken into account. Regarding rights expression languages and policy languages, standards like MPEG-21 Rights Expression Language (REL), Open Digital Rights Language (ODRL) and eXtensible Access Control Markup Language (XACML) are considered. Regarding services for content management, the Multimedia Information Protection And Management System (MIPAMS), a standards-based implemented architecture, and the Multimedia Service Platform Technologies (MSPT), also known as MPEG-M standard, are considered. The contribution of this thesis is divided into two parts, one devoted to languages interoperability and the other one devoted to services interoperability, both addressed to multimedia content management. They are briefly described next. The first part of the contribution describes how MPEG-21 REL, ODRL and XACML can interoperate, defining the mapping mechanisms to translate expressions from language to language. The mappings provided have different levels of granularity, starting from a mapping based on a programmatic approach coming from high-level modelling diagrams done using Unified Modelling Language (UML) and Entity-Relationship (ER). The next level of mappings includes specific mappings between MPEG-21 REL and XACML and ODRL and XACML. Finally, a more general solution is proposed by using a broker. Part of this work was done in the context of the VISNET-II Network of Excellence and the AXMEDIS Integrated Project. The findings done prove the validity of the interoperability methods described. The second part of the contribution describes how to describe standards based building blocks to provide interoperable services for multimedia content management. This definition is based on the analysis of existing content management use cases, from the ones involving less security over multimedia content managed to the ones providing full-featured digital rights management (DRM) (including access control and ciphering techniques) to support secure content management. In this section it is also presented the work done in the research projects AXMEDIS, Musiteca and Culturalive. It is also shown the standardisation work done for MPEG-M, particularly on elementary services and service aggregation. To demonstrate the usage of both technologies a mobile application integrating both MPEG-M and MIPAMS is presented. Furthermore, some conclusions and future work is presented in the corresponding section, together with the refereed publications, which are briefly described in the document. In summary, the work presented can follow different research lines. On the one hand, further study on rights expression languages and policy languages is required as new versions of them have recently appeared. It is worth noting the standardisation of a contract expression language, MPEG-21 CEL, which has also to be further analysed in order to evaluate its interoperability with rights and policy languages. On the other hand, standard initiatives must be followed in order to complete the map of SB3's, considering MPEG standards and also other standards not only related to multimedia but also other application scenarios, like e-health or e-government

Traffic engineering multi-layer optimization for wireless mesh network transmission a campus network routing protocol transmission performance inhancement

This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel UniversityThe wireless mesh network is a potential network for the future due to its excellent inherent characteristic for dynamic self-healing, self-configuration and self-organization. It also has the advantage of easy interoperability networking and the ability to form multi-linked ad-hoc networks. It has a decentralized topology, is cheap and highly scalable. Furthermore, its ease in deployment and easy maintenance are other inherent networking qualities. These aforementioned qualities of the wireless mesh network bring advantages to transmission capability of heterogeneous networks. However, transmissions in wireless mesh network create comparative performance based challenges such as congestion, load-balancing, scalability over increasing networks and coverage capacity. Consequently, these challenges and problems in the routing and switching of packets in the wireless mesh network routing protocols led to a proposal on the resolution of these failures with a combination algorithm and a management based security for the network and its transmitted packets. There are equally contentious services like reliability of the network and quality of service for real-time multimedia traffic flows with other challenges such as path computation and selection in the wireless mesh network. This thesis is therefore a cumulative proposal to the resolution of the outlined challenges and open research areas posed by using wireless mesh network routing protocol. It advances the resolution of these challenges in the mesh environment using a hybrid optimization – traffic engineering, to increase the effectiveness and the reliability of the network. It also proffers a cumulative resolution of the diverse contributions on wireless mesh network routing protocol and transmission. Adaptation and optimization are carried out on the wireless mesh network designed network using traffic engineering mechanism and technique. The research examines the patterns of mesh packet transmission and evaluates the challenges and failures in the mesh network packet transmission. It develops a solution based algorithm for resolutions and proposes the traffic engineering based solution.. These resultant performances and analysis are usually tested and compared over wireless mesh IEEE802.11n or other older proposed documented solution. This thesis used a carefully designed campus mesh network to show a comparative evaluation of an optimal performance of the mesh nodes and routers over a normal IEE802.11n based wireless domain network to show differentiation by optimization using the created algorithms. Furthermore, the indexes of performance being the metric are used to measure the utility and the reliability, including capacity and throughput at the destination during traffic engineered transmission. In addition, the security of these transmitted data and packets are optimized under a traffic engineered technique. Finally, this thesis offers an understanding to the security contribution using traffic engineering resolution to create a management algorithm for processing and computation of the wireless mesh networks security needs. The results of this thesis confirmed, completed and extended the existing predictions with real measurement
