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

The industry and research institutes are steadily adopting IMS and are building internal IMS testbeds for prototyping of services and validation of all-IP concepts. The client applications triggering testing scenarios and demonstrating services within the testbed are important for the overall quality and visibility of the test setup. The IMS applications which are available today concentrate only on one task of testbed support either testing or demonstrating and thus often support only a limited set of basic services likes VoIP, messaging and presence. This paper describes the requirements for an IMS client application framework and shows some prototype work in writing such a framework which can be used to create individual NGN testbed applications.

An IMS Client Application Framework for Emerging NGN Testbeds

The Internet as the largest global recognized communication system is in constant change and evolves in dimensions of technology, capacity, availability and size continuously since its beginnings in the late 1960's. The openness and its continuous change became characteristics of the Internet nowadays, but were no available in its origins. This chapter presents an overview about the telecommunication network and control platform evolution from classic fixed Circuit-Switched (CS) on to current fixed and mobile Next-Generation-Networks (NGN) towards future networks trends. Furthermore the Fixed-Mobile-Covergence (FMC) is presented and technology specific details are presented exemplarily.

Die Telekommunikationswelt steht vor einem entscheidenden Umbruch. Waren die letzten Dekaden der Telekommunikation masgeblich durch Telefonie und sprachbasierte Einheitsmehrwertdienste gepragt, die festen und spater auch mobilen Netzbetreibern komfortable Einnahmen bescherten, zeigt heute sowohl „Voice over IP“ — also die Vermittlung von Sprache uber das Internet — als auch das so genannte Web 2.0 der Internetbasierten Multimedia-Anwendungen, wie Internettechnologien nachhaltig die (Tele)kommunikationslandschaft verandern. Sinkende Einnahmen durch immer gunstigere Sprachminuten und die steigende Verbreitung von festen und mobilen Internetzugangen, sowie die damit einhergehenden, zunehmend multimedialen Internetdienste fuhren zu der berechtigten Frage, wie zukunftig noch Geld in der Telekommunikationswelt zu verdienen ist. Die Konvergenz von Telekommunikation, Internet, Fernsehen und Unterhaltung — das so genannte Triple Play — zwingt dabei allerdings auch die anderen beteiligten Branchen zu dieser Fragestellung. „To bitpipe or not to bitpipe“ ist dabei die wesentliche Frage fur die traditionellen Netzbetreiber, d.h. zieht man sich auf die effiziente und durchaus profitable Bereitstellung von Netzzugangen zuruck, oder entwickelt man eigene Dienstkonzepte im Wettbewerb zur offenen Internetdienstwelt.

Kommunikationsplattformen für maßgeschneiderte Dienste

In the contemporary cloud computing environment, the various cloud providers adopt different architectures for their systems and usually these are not compatible. The scalable exchange of information about these heterogeneous resources is often not addressed; still this represents an interesting challenge, since different Cloud systems and vendors have different ways to describe and invoke their services, to specify and communicate requirements. Hence a way to provide a common access to Cloud services and to discover and use required services in Cloud federations is highly desirable. The IEEE P2302 Intercloud ap- proach is to define a scalable architecture and to adopt the OMN (Open-Multinet) ontology for supporting its operation. Our work specifically describes the inner workings of the Intercloud system in terms of the Intercloud Federation Application Programmers Interface (API), which are in turn based on the semantic definition of resources, Service Level Agreements (SLAs), and Bearer Network Provisioning Metadata.

Semantic-based Network Exchange for the IEEE P2302 Intercloud Approach

According to the invention, a method and a device for adapting a data path for a mobile entity (201) in a communication network are suggested. The communication network has at least one forwarding entity (203, 205) for providing data packets for the data path and a plurality of mobility binding entities (207, 209) for forwarding data packets on the data path, wherein a first mobility binding 10 entity (207) is allocated to the data path for the mobile entity (201) according to binding information for the mobile entity (201). The method has a step receiving (101) a re-allocation request for re-allocating a second mobility binding entity (209) to the data path for the mobile entity (201), a step of updating (103) the binding information for the mobile entity (201) on the basis of the received re-15 allocation request, a step of forwarding (105) data packets received from the forwarding entity (203, 205) by the first mobility binding entity (207) to the second mobility binding entity (209) until the updated binding information is received at the forwarding entity (203, 205), and a step of forwarding (107) data packets from the forwarding entity (203, 205) to the second mobility binding entity (209) after the 20 updated binding information is received at the forwarding entity (203, 205).
