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

Summary form only given. In regard to the emerging Web 2.0 service explosion the telecommunications landscape is evolving rapidly from a voice and messaging centric environment towards an open multimedia service and content market. Whereas historically specific telecommunication services (such as voice telephony) have been provided in dedicated network environments (such as the PSTN/ISDN) with specific service delivery platforms (SDPs) in charge for the control of value added services (such as the intelligent network), we today see the notion of seamless interactive multimedia communication and information services, often referred to as X-Play services, on top of converging networks. This convergence of fixed and mobile telecommunication networks with the Internet is driving the definition and implementation of the so-called next generation network (NGN).

Considering context information, namely location, in order to create new services has become a commercial trend. The innovative approaches that context-aware mechanisms make possible are being targeted by service providers of diverse areas. On the other hand, Service Oriented Architectures play a central role in allowing component reuse and low cost service creation. Together with IP Multimedia Subsystem enable the convergence of telecommunications and web services, allowing the network transport technologies to be abstracted from the services above. By integrating these three technologies, a number of synergies can be explored. Existing services can be easily enriched with context information, made available on a variety of networks and new services can be composed using previously existing building blocks. This paper explains how this integration can be achieved, and demonstrates the potentialities of this architectural paradigm with a prototype service.

CATS: Context-Aware Triggering System for Next Generation Networks

The rapid progress being made recently in fixed and wireless access technologies that are envisioned to change the way we consume multimedia content show that the evolution of IP-based networks will be largely driven by multimedia service delivery requirements. The recent growth in the demand for IP-based streaming applications has challenged mobile operators on the management of the growth of traffic in their network. The delivery of several multimedia streaming applications composing live or store multimedia content such as public events or broadcast TV are transmitted according to pre-subscription. They occupy a high level of resources for which static congestion estimation mechanisms are not working. This paper introduces a novel solution for resource prediction of multimedia content delivery based on information gathered during the service subscription process in which users interested in certain multimedia service register (subscribe to) with the service provider for multimedia content delivery. This method represents an efficient use of pre-existing information, is easy to deploy and highly cost effective in comparison to traditional monitoring system employing dedicated traffic metering hardware.

Network Resources Pre-Reservation for Multimedia Content Delivery in Heterogeneous Wireless Networks

Next Generation Network (NGN) research initially focused on access network convergence by harmonizing the session control plane, giving birth to the IP Multimedia Subsystem (IMS). Shortly after, the focus shifted towards the NGN service plane, generating versatile and flexible IMS-based Service Delivery Platforms which predominantly are designed according to Service Oriented Architecture (SOA) principles. These NGN service environments usually comprise a multitude of service enablers that allow for dynamic service compositions. This work focuses on manageability aspects of NGN service composition, investigating active monitoring mechanisms for root cause analysis. It will quantify the improvements brought by service dependency information into the fault localization and fault recovery process. NGN testbed evaluations furthermore analyze the impact of different monitoring policies on the overall fault management performance.

Automated Root Cause Analysis for IMS and SDP

With the upcoming network function virtualization (NFV), aiming at deployment of core network functionality on top of cloud infrastructures, there is a stringent need for developing an appropriate evaluation process and the afferent automatic testing solutions. Before NFV, only black-box testing was needed, due to the physical isolation of the components in separate boxes. With NFV, the network components are software-only and share the same infrastructure. In NFV, a new benchmarking methodology has to be consider, accounting also for the infrastructure usage. This paper introduces such an evaluation methodology and a practical implementation, enabling the automatic evaluation how a specific virtualized packet core solution (vEPC) behaves on top of a specific data center with a specific network usage pattern. It enables the quantitative evaluations of the system from external perspective, testing how the service is perceived by the end subscribers, correlated with the system resources usage. Furthermore, the benchmarking methodology was applied and adapted based on the measurements done for the Fraunhofer FOKUS Open5GCore toolkit, a vendor independent software-only core network, through this engineering an efficient benchmarking process and giving an example of knowledge which can be extracted using such tools.
