From the Publisher:
An agent is an entity with domain knowledge, goals and actions. Multi-agent systems are a set of agents which
interact in a common environment. Multi-agent systems deal with the construction of complex systems involving multiple agents and their coordination. A multi-agent system (MAS) is a distributed computing system with
autonomous interacting intelligent agents that coordinate their actions so as to achieve its goal(s) jointly or competitively.

Multi-access edge computing (MEC) is an emerging ecosystem, which aims at converging telecommunication and IT services, providing a cloud computing platform at the edge of the radio access network MEC offers storage and computational resources at the edge, reducing latency for mobile end users and utilizing more efficiently the mobile backhaul and core networks This paper introduces a survey on MEC and focuses on the fundamental key enabling technologies It elaborates MEC orchestration considering both individual services and a network of MEC platforms supporting mobility, bringing light into the different orchestration deployment options In addition, this paper analyzes the MEC reference architecture and main deployment scenarios, which offer multi-tenancy support for application developers, content providers, and third parties Finally, this paper overviews the current standardization activities and elaborates further on open research challenges

On Multi-Access Edge Computing: A Survey of the Emerging 5G Network Edge Cloud Architecture and Orchestration

The technologies, architectures, and methodologies traditionally used to develop distributed applications exhibit a variety of limitations and drawbacks when applied to large scale distributed settings (e.g., the Internet). In particular, they fail in providing the desired degree of configurability, scalability, and customizability. To address these issues, researchers are investigating a variety of innovative approaches. The most promising and intriguing ones are those based on the ability of moving code across the nodes of a network, exploiting the notion of mobile code. As an emerging research field, code mobility is generating a growing body of scientific literature and industrial developments. Nevertheless, the field is still characterized by the lack of a sound and comprehensive body of concepts and terms. As a consequence, it is rather difficult to understand, assess, and compare the existing approaches. In turn, this limits our ability to fully exploit them in practice, and to further promote the research work on mobile code. Indeed, a significant symptom of this situation is the lack of a commonly accepted and sound definition of the term mobile code itself. This paper presents a conceptual framework for understanding code mobility. The framework is centered around a classification that introduces three dimensions: technologies, design paradigms, and applications. The contribution of the paper is two-fold. First, it provides a set of terms and concepts to understand and compare the approaches based on the notion of mobile code. Second, it introduces criteria and guidelines that support the developer in the identification of the classes of applications that can leverage off of mobile code, in the design of these applications, and, finally, in the selection of the most appropriate implementation technologies. The presentation of the classification is intertwined with a review of state-of-the-art in the field. Finally, the use of the classification is exemplified in a case study.

The FOKUS Open IMS Core—A Global IMS Reference Implementation

The vision for future telecommunications is often described by the slogan “information at any time, at any place, in any form” driven by both the society’s increasing demand for “universal connectivity” and the technological progress in the area of mobile computing and personal communications. In order to realize this vision a Personal Communications Support System (PCSS) has been developed within a project of the R & D-programme from the DeTeBerkom GmbH, a subsidiary of the Deutsche Telekom AG, by Technical University of Berlin. The PCSS is designed to support advanced personal communications capabilities, i.e. personal mobility, service personalization, and advanced service interoperability, in a uniform way to numerous communication applications in distributed multimedia inhouse environments. From a functional perspective, the PCSS provides enhanced Intelligent Network (IN) and Universal Personal Telecommunications (UPT) capabilities with respect to customer addressing (based on logical names instead of numbers) and advanced customer control capabilities. From a design perspective, the centralistic IN/UPT approach to the realization of service logic has been replaced by a highly distributable, object-oriented approach based on X.500/X.700/Telecommunication Management Network (TMN) concepts. This paper presents the basic aspects of the PCSS, including design criteria, system functionality, platform design and evolution issues.

Generic Personal Communications Support for Open Service Environments

The main idea for launching the FOKUS IMS Playground testbed in 2004 was to provide R&D for earlier IMS developments in order to validate existing and emerging IMS standards The IMS Playground was extended appropriately to be used on top of new access networks as well as to provide new seamless multimedia applications The FOKUS testbed originated from own developments as well as major industry players, and is being used by academic and industrial partners for prototyping new IMS related components, protocols, and applications The next target is to integrate FOKUS testbed in a Pan-European Network of testbeds in order to reach a broader community with the benefits of such a testbeds federation This paper describes the FOKUS experiences at running the IMS Playground, providing a look into administrative and technical issues that need consideration on integrating testbeds This view can be applied to run any kind of testbed The paper presents the descriptions of the issues from service/capabilities offer to test execution, as well as the intrinsic benefits and challenges

Correspondence should be addressed to Christian Riede, christian.riede@fokus.fraunhofer.deReceived 1 April 2008; Revised 6 August 2008; Accepted 20 October 2008Recommended by Ravi SharmaThe convergence of telecommunication, cable TV, and broadcast networks towards the Internet technology will enable theprovision of emerging multimedia services as well as the integration of rich communication capabilities with TV services.However, enabling eﬃcient delivery of interactive personalized multimedia services with mobility support requires an advancedoverlay control framework. The IP Multimedia Subsystem (IMS) oﬀers the basic functions to manage multimedia sessions overdiﬀerent access networks. This paper outlines current standardization activities that address the provisioning of TV servicesover IP networks—known as IPTV—and proposes a novel end-to-end overall architecture based on IMS that enables thedelivery of converged multimedia services. Furthermore, the paper presents the FOKUS Media Interoperability Lab as a referenceimplementation of this framework which covers a widespread spectrum of converged interactive scenarios. The ﬁnal section givesan impression of the system performance by providing the end-to-end signaling delay of a session setup for live TV service deliveredover unicast transmission mode.Copyright © 2008 Adel Al-Hezmi et al.

The Pan-European laboratory - Panlab - is based on federation of distributed testbeds that are interconnected, providing access to required platforms, networks and services for broad interoperability testing and enabling the trial and evaluation of service concepts, technologies, system solutions and business models. In this context a testbed federation is the interconnection of two or more independent testbeds for the temporary creation of a richer environment for testing and experimentation, and for the increased multilateral benefit of the users of the individual independent testbeds. The technical infrastructure that supports the federation is based on a web service through which available testing resources can be queried and requested. The available resources are stored in a repository, and a processing engine is able to identify, locate and provision the requested testing infrastructure, based on the testing users' requirements. The concept is implemented using a gateway approach at the border of each federated testbed. Each testbed is an independent administrative domain and implements a reference point specification in its gateway.
