Approximate computing (AxC) has advanced from being an emerging design paradigm to becoming one of the most popular and effective methods of energy optimization for applications in the domains of computer vision, image/video processing, data mining, analytics, and search. The simultaneous rise of artificial intelligence (AI) has provided an additional thrust to the adoption of various AxC techniques in intelligent edge platforms where energy-efficiency is not only desirable but necessary. In spite of the big rise in interest for AxC, the adoption of approximate hardware has mostly been limited to only one component of the system (usually the processing subsystem) which often contributes only a fraction of the overall system-level power. A full system approach to AxC enables us to extend approximations to other subsystems, such as the memory, sensor, and communications subsystems. This paper presents the foundational concepts of an approximate TinyML system that applies approximations synergistically to multiple subsystems in an edge inference device. These approximations are applied intelligently to significantly reduce energy while incurring a negligible loss in application-level quality. We demonstrate multiple versions of an approximate smart camera system that can execute state-of-the-art deep neural networks (DNNs) while consuming only a fraction of the total energy in a typical system.

5G network technology can offer major benefits to the Media & Entertainment (M&E) sector in addressing the challenges associated with production and delivery of mobile, ip-driven media services, such as smart media production, 4K/8k video streaming, and live virtual reality. The massive growth in demand for such advanced services has created the need for innovative experimentation facilities. These can support the M&E industry in continually enhancing user experience and creating efficiencies in how content is produced and delivered across mobile networks. Such support is the core goal of the H2020-funded 5GMediaHUB project, which aims to accelerate the testing and validation of innovative 5G-enabled media applications and Network applications, through an open, integrated and fully featured experimentation facility. This will significantly reduce the service creation lifecycle and minimise time-to-market, thus enhancing the competitiveness of facility users. 5GMediaHUB will create an elastic, secure and trusted multi-tenant service execution and Network Application development environment, based on an open, cloud-based architecture and APIs. The project will integrate this testing and validation system with two well-established 5G testbeds at CTTC, Spain and Telenor, Norway. In this article, we first introduce the key features of the 5GMediaHUB experimentation facility. These features ensure effective operation of advanced media applications over 5G, and support developers in minimising application performance uncertainties prior to widescale commercial deployment. Next, the deployment and implementation of the 5GMediaHUB infrastructure is presented, before the deployment and validation of the project’s use cases are discussed. These use cases will explore the topics of Interactive Media, Content Creation and Media Distribution, all enabled through advanced 5G connectivity.

The fifth generation of mobile communications, promises to offer very high achievable data rate, very low latency, ultra-high reliability, along with supporting a wide range of new applications and use cases. In order to increase network scalability, service flexibility and to improve mobility management in 5g wireless networks, two new concepts have emerged, namely Network Functions Virtualization (NFV) and Software Defined Wireless Networking (SDWN). In this study, we designed and implemented a network architecture based on an open-source software-based LTE implementation named as OpenAirInterface (OAI). OAI emulation platform is an integrated tool allowing large-scale networking experimentation. The latter can be used for prototyping innovation scheduling algorithms, making the majority of new architecture. SDWN network technology has emerged in order to deliver a high quality multiple performance system with cost benefits that includes several processes such as live monitoring, reconfiguration, control delegation and faster data-transfer. In order to test some key enablers and features of 5G mobile networks, we provide a topology that combines SDWN and NFV technologies to handle the fulfilment of network slices by running Mosaic 5g FlexRAN software on top of the OAI platform. Moreover, Clearwater ip multimedia subsystem (IMS) is integrated to provide voice over ip (Voip) service between subscribers and a Wi-Fi Access point (AP) is added to network in order to establish a heterogeneous wireless network (HetNet). Our results can serve as a reference for future optimization by the open source community.

As of today, telecommunication providers are exploiting the possibilities offered by the cloud paradigm to efficiently decouple physical network resources, like hardware equipment, optical interfaces and cables, from offered services, for instance multimedia content delivery and data storage. Among technologies conceived to implement this paradigm, containerization stands out. It can be considered as an evolution of classic virtualization, where software instances called containers are designed to offer specific network functionalities by relying on a separate infrastructure composed of virtual machines and hardware. In line with this new trend, we characterize, from an availability viewpoint, an ip multimedia subsystem (IMS) architecture deployed in a containerized environment (dubbed cIMS), which represents a pivotal part of novel network architectures such as 5G. Firstly, we model the availability of cIMS by employing both Reliability Block Diagram (RBD), to capture logical dependencies among cIMS nodes, and Stochastic Reward Networks (SRN), to characterize individually the probabilistic behavior of each node. Then, also supported by an ad-hoc automated procedure, we carry out an experimental assessment of a typical telecommunication network service satisfying a desired availability constraint, whose results are some feasible cIMS configurations that can be deployed.

Being one of the most solicited content (opinions) sharing platforms, Twitter is a granary of information serving as a base for our service discovery/exposure approach proposed in this paper. The growth of data caused by the internet growth has led to the birth of a growing number of services, making the task difficult for telecommunication operators in competition. In this paper, we propose a dual service discovery/exposure approach to reduce the gap between offered services and subscribers’ needs in an IMS context. This approach is based on opinion mining related to Twitter trending topics in order to estimate the sensitivity of the target user to a service or another. Compared to both the classic approach and the collaborative service discovery/exposure approach, our results show an improvement in the accuracy and error of the service targeting at the target user’s starting phase on the operator’s network. © 2020, Springer Nature Switzerland AG.

In this era of mobile Internet, people can quickly and easily access multimedia services and applications through mobile phones. And multimedia services are ubiquitous in life, such as text, pictures, voice, and video, to convey and receive media that give people all kinds of information. In addition, with the rapid development of the Internet of Things, all the devices around the world have networking functions, so that people not only enjoy application services on mobile phones but also want to further develop with devices of our living environments. ip multimedia subsystem (IMS) is a platform that can integrate multimedia services. If people want to enjoy IMS services directly through peripheral devices (i.e., non-IMS devices), they must be authorized by IMS devices to be trusted devices. This paper is based on Gateway as a trusted intermediary role, connecting peripheral devices in the IMS network so that these non-IMS devices can also talk with the IMS device, so IMS users can also use his peripheral devices for IMS talk service. © 2019 IEEE.

The promise of high bandwidth and low latency for real-time applications are still open issues and challenges in Next Generation Networks (NGN). Thus, sophisticated management is required to improve the Quality of Service (QoS) in these networks and to respect the available network resources. In this paper, we propose a new approach of hybrid criticality to manage dynamically multimedia traffic and requests customers through Differentiated Service (Diffserv) policies using Adaptive Neuro-fuzzy Inference System (ANFIS) and implement them to the Policy Control Rule Function (PCRF) for selecting the appropriate Code Point (CP) to users. We extend the proposed approach in IMS networks with PCRF and PCEF interaction. This approach is based on internal and external factors for making-decision. The internal factors depict the QoS parameters and the external factors characterize the user information. This paper presents a new architecture ANFIS-based for Long Term Evolution (LTE) packet core to enhance QoS management. Simulations show that by adopting hybrid criticality using ANFIS, an improved QoS parameter and time response are gained compared to the classical cases where all flows exhibit the same level of criticality and compared also to Fuzzy Logic technique.

For many years, media transport and processing in professional media environments have been accomplished using specialized hardware. The flexibility of ip networking and Media Function Virtualization (MFV) can enable broadcasters to build cost-efficient architectures for the deployment of media services. These architectures can be further exploited to perform decomposition of Virtual Media Functions (VMFs) resulting in improved utilization of the MFV Infrastructure (MFVi) resources. To this end, this paper presents an algorithm aimed at optimizing the VMF Forwarding Graphs (VMF-FGs) media services. A first-fit based heuristic is also proposed for deploying media services on a given MFVi. The evaluation results indicate that VMF-FG decomposition can significantly improve the request acceptance ratio and reduce resource requirements.

The IMS P2P network is a solution that allows the improvement of the IMS network to support p2p architectures in respect of access network technologies, in this article we propose the collaboration between IMS and the adaptation of quality with scalable video coding and peer-to-peer networks. The proposed scheme has been tested and evaluated in NS2, the proposed architecture demonstrated the adaptation of SVC video quality using a complex model of adaptation based on user performance (CPU, RAM, Bandwidth, battery life), In order to respect the heterogeneity of the equipment, so that each user receives only the flow that suits their performance. We will also make two types of subjective evaluation (Mean Opinion Score (MOS)) and objective (peak signal to noise ratio (PSNR)) and so we will evaluate the various network parameters,.
