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.

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.

Understanding code mobility

Abstract The 5th Generation of mobile networks (5G) is expected to be rolled out by 2020. New and revolutionary applications are already being envisioned, real-time control of machines, the Tactile Internet for wireless, Industry 4.0, the Internet of Things and self-driving cars, among others. To make this possible important enhancements and improvements in today's existing telecommunication technologies form an end-to-end perspective are required. Early testing and fast prototyping of new approaches and solutions will help to shape the evolving technologies. One of the technical enablers for 5G are two concepts based on the softwarisation and virtualisation of the core network, known as Software Defined Networking (SDN) and Network Function Virtualisation, NFV. Fraunhofer FOKUS has set up the Open5GCore testing environment to start shaping, together with its partners, the nascent 5G technologies by addressing these topics together with other relevant technological developments. After a short motivation, the architecture of the open5GCore is presented, followed by a functional description of supported features.

Prototyping new concepts beyond 4G – The Fraunhofer Open5GCore

This paper presents and discusses the major trends in two important areas: distributed mobile computing and personal telecommunications. The evolution in these two areas indicates a major paradigm shift towards a merging of computer and telecommunications technologies into a world of mobile, interactive computing and communications. The resulting applications comprise the handling, exchange, retrieval, and processing of data, voice, and video streams as ubiquitous services based on an integrated computing-/telecommunications supporting environment. Based on important developments in both areas, a TMN-based Personal Communications Support System (PCSS) will be introduced, which provides personal mobility and service personalization capabilities in a generic way for a broad range of telecommunication services.

On the Convergence of Distributed Computing and Telecommunications in the Field of Personal Communications

After several decades of circuit switched technology, mobile telephony is moving towards all-IP network architecture. The convergence to IP, on a one hand, brings many advantages, but makes mobile networks easier to be attacked. In this paper, a security framework is discussed addressing two security challenges: DIAMETER-related threats and subscriber malicious activities. The former is taken into account as the fast growing of DIAMETER in the evolving 4G mobile networks. The latter can be mitigated by analyzing DIAMETER signaling traffic and applying appropriate techniques to them. The framework being investigated is flexible and some of the developed components are already open source and being used by the DIAMETER community.

A DIAMETER based security framework for mobile networks

Provisioning of multimedia content to users being in different contexts (e.g. device capabilities, network conditions, location, user mode, user activity, etc.) and associated to various business models (e.g. prepaid, post-paid, session-based, etc.), challenges service providers to develop service capabilities that can be shared across all services and make use of network delivery functions more efficiently. Enabling the delivery of multimedia services following Service Oriented Architecture (SOA) paradigm is the main objective of this work. In this paper we present a set of basics elementary functions that enable efficient multimedia content delivery over various transmission modes (unicast, multicast or broadcast) and different heterogeneous networks, utilizing IP Multimedia Subsystem (IMS) to control and manage sessions, hiding therefore access dependencies and network complexity. A reference architecture is described along with implementation details that allow the integration with a converged media delivery framework. Then we present the performance of the implementation as well as the related signaling interfaces that were evaluated through a set of live measurements.

SOA-based multimedia streaming enabler over IMS networks

In a multi-network environment, users can receive services via several networks, protocols, and connected devices. These services are usually bound to their specific technology and often limited to a dedicated service provider domain. We are developing a platform overcoming these limitations by enabling information sharing beyond the boundaries of network technologies and services. In this paper, we propose a service architecture for the interaction of users/personas and services in a converged Internet and Telecom service space on top of multiple access networks. This is achieved by convergence of multiple separated communication channels on service layer in an IP Multimedia Subsystem based Telecom environment. We design a service platform enabling and controlling information flow across networks and services.
