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 evolution of mobile network architecture is an essential part in the development process of the fifth generation (5G) of cellular mobile systems, and that is through the incorporation of advanced cloud technologies and network function virtualization techniques. The new network architecture needs to support a wide range of high data rate applications and services, offering capacities of up to multiple gigabits per second, yet meeting extremely stringent latency and reliability requirements under a diverse variety of scenarios. Thus the automation of network control and overall system management to achieve such an ambitious set of performance targets became crucial. Significant global effort for the necessary new technologies has been initiated.

Research & standards: advanced cloud & virtualization techniques for 5G networks [Guest Editorial]

Currently, a number of research activities worldwide focus on resource federations to enable remote resource access and the setup of large scale experiments. With the global efforts in sharing experimental facility resources across organizational boundaries, interoperability issues are becoming increasingly important. To this end, this paper describes a model that defines the necessary entities for inter resource federation scenarios. The model is then discussed by means of a concrete use case federating Panlab and PlanetLab resources. In this respect Panlab and PlanetLab are considered to be federations themselves. Our findings show that the two approaches can be matched following the general model. This allows for federating resources not only across the boundaries of administrative (organizational) domains but even across the boundaries of federations. Those federations in themselves provide collections of resources offered by several administrative domains and use different control frameworks to enable resource access and management.

Interoperability in Heterogeneous Resource Federations

Due to a rapidly shifting technology and competitive market environment, Telecommunication and Internet Services are constantly subject to changes, creating new challenges and needs for the industry to keep generating revenues. A high level of customization is therefore identified as a key enabler for achieving customer satisfaction and improving their quality of experience. Enriching services with innovative approaches such as context-aware, adaptable and interactive mechanisms enable the vendors to deliver tailored and personalized experiences to its customers. This article presents a concept to integrate policy-based decision mechanisms into the architecture of a Next Generation Network (NGN)-based converged messaging enabler for supporting adaptive personalization and context-aware service delivery across heterogeneous networks and messaging technologies. The system reacts to context changes and makes real-time decisions about handling incoming messages according to the users' preferences. A prototype has been implemented as part of the Open SOA Telco Playground testbed at Fraunhofer FOKUS.

Enabling context-sensitive communication experiences

This paper gives an overview of the basic architectural migration steps from current Intelligent Network (IN) based service platforms toward emerging Telecommunications Information Networking Architecture (TINA) based service environments. This evolution can be regarded as a stepwise replacement of IN functional entities by means of a set of appropriate TINA computational objects realised on top of a Distributed Processing Environment (DPE). Hence in the course of evolution, a service platform may comprise two parts; a still IN-conformant part and an already TINA-conformant part. This raises the need for the definition of appropriate adaptation units, allowing for example an IN Service Switching Function to interwork with TINA objects implementing the service control and management logic. Whereas the upper part of the adaptation concentrates on the mapping of concrete IN Application Protocol operations onto appropriate method invocations of TINA computational objects, on the bottom this adaptation has to deal with the interworking between the Signalling System No. 7 network protocols, and inter-DPE-node protocols.

From IN toward TINA - Potential Migration Steps

In the context of the emergence of a global service market enabling the ubiquitous access to information and communication services, the new paradigm of mobile intelligent agents is attracting strong interest throughout the research community, as well as the information and telecommunication industries. After giving a brief account of the development of the agent paradigm and the basic terminology, this paper analyzes different application fields of this highly promising technology. Among the reviewed application areas are electronic markets, virtual enterprises, flexible information systems, and the domain of mobile and personal communications. The analysis leads to the identification of a number of roles agents may take on. The capabilities that an agent exhibits in the course of performing its role can be expressed as levels of agent intelligence, mobility, communicability, autonomy and cooperation ability, i.e. the agents skills.
