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

Privacy, confidentiality, data integrity and intrusion detection & prevention are the security methodologies to secure communication in all fields of networking, cellular and fixed communication. With the emerging of IP Multimedia Subsystem (IMS) and Next Generation Networks (NGN), there is a great need to provide secure and trusted environment to user's sensitive information and to provide measures to protect IMS operator's assets. The IMS needs powerful security association between multimedia client and the network before access is granted to multimedia services because of low security dependency of PS-domain. The security features to accomplish in securing access to the IMS are to protect SIP signalling, user authentication and authorization, development of network domain security and trusted domain using policy based security associations.

In this paper we present the security and privacy management framework for IP Multimedia Subsystem (IMS) which consists of IMS Authentication & Key Agreement (AKA), Network Domain Security, and IMS Access Security for SIP-based and HTTP-based services. The presented IMS security framework is developed for Open IMS & 3Gb Testbed of Fokus, Fraunhofer with the objective to manage security across different interfaces like air contact between user and IMS core, inter and intra domains interfaces and between IMS Core and Application Servers. It also deals with security when the user is roaming or in home network and security for UMTS access networks. This independent security framework provides additional protection against security attacks to IMS domain along with the PS (Packet Switched) domain security or IP Security.

With the increasing deployment of 5G Non-public Networks, the telco environment is becoming massively multi-administrated with a wide range of full networks deployed close and covering only the use case area. To benefit the most of this, a roaming solution must be set in place enabling devices to safely communicate using visited infrastructures either with local service or with the ones from the home networks. As a first step in this direction, this article proposes a new architecture for Non-public Networks roaming, stemming from the 3GPP 5G macro-operator roaming and adapted to the specifics of the communication for geographically-distant, small networks interconnected by third party unreliable backhauls. Furthermore, the architecture is exemplified, and its potential is evaluated as further extensions to the Fraunhofer FOKUS Open5GCore, showing that it outperforms today’s roaming solution in terms of flexibility and privacy of deployment, backhaul usage and reduced network administration.

The design, implementation and provision of services in the Internet scenario are forcing both the traditional area of client/server distributed systems and the emerging sector of agent technology towards the definition of a common distributed middleware, i.e., a set of basic facilities that can be ubiquitously accessed by any distributed component as an integrated part of the enhanced communication infrastructure. This middleware should not only be the basis where designers start for the realization and deployment of their services, but also be flexible enough to permit the easy and rapid extension of the common infrastructure to accommodate evolving system/service requirements and expectations of final users.

Middleware technologies: CORBA and mobile agents

Technical and economic opportunities of cloud computing become the focus for Internet applications and at the same time also for telco support infrastructures and network services. In fact, many telco providers are consolidating their service infrastructures towards converged and all-IP next generation networks providing typical telco services within LTE (and soon 5G) and also fixed network environments, e.g., often still adopting IP Multimedia Subsystem (IMS) architecture solutions. This telco service infrastructure evolution requires a significant upfront investment in the necessary hardware and software, thereby slowing down the adoption process significantly more than any other Internet application. Cloud computing applied to telco infrastructures can allow pay-per-use business models and significantly lower investment risks by providing telco infrastructure functionality as Virtual Network Functions (VNFs) on top of a Network Functions Virtualization (NFV) platform. For this purpose we propose a quality audit and resource brokering framework that is fully NFV-compliant. Its current and reported implementation specifically targets IMS services because of the still relevant role played by IMS in converged provisioning and the wide availability of IMS deployment testbeds to validate the proposal. In particular, the proposed solution can monitor the quality offered by VNFs and scale in/out depending on dynamic requirements; it is fully based on industrial standards and open-source reference implementations, thus enabling rapid adoption in real industrial environments.

Quality Audit and Resource Brokering for Network Functions Virtualization (NFV) Orchestration in Hybrid Clouds

The high popularity of mobile computing and the increasing number of powerful mobile phones that are able to access high speed data networks pave the way to new scenarios for multimedia applications for mobile devices. Older limitations on network access, displaying capabilities and computing power have been surmounted. The users now have powerful devices and more bandwidth and expect that new, as well as traditional, multimedia applications are available on them. There is a need to offer users a coherent experience and provide multimedia independent of the constrains of the device in which it runs, and the network access technologies used. A way to achieve this is to use a software framework on top of which applications can be built. This framework is able to run on top of a wide variety of mobile platforms and enables a fast and easy deployment of multimedia clients. This paper analyzes the requirements and describes the architecture of Multimedia Open Internet Services and Telecommunication Environment (MONSTER), a framework for mobile multimedia clients currently developed at the Fraunhofer Institute for Open Communication Systems (FOKUS).
