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

Present network devices are able to access simultaneously services over various technologies e.g. UMTS, WLAN, WiMAX etc. each of these having different quality of service characteristics. Also for a specific service, different levels of quality could be offered depending on the client profile and on the momentary network capacities, giving the possibility of creating tiered access to resources. In order to enhance the network usability to these new conditions we propose an optimized, network driven QoS management and provisioning model. It is also considering a localization mechanism, doubled by a QoS control of the access networks. This paper focuses on a single operator scenario, which deploys multiple access technologies using an IMS signaled 3GPP System Architecture Evolution.

A Network Controlled QoS Model over the 3GPP System Architecture Evolution

Next generation networks offer dedicated subsystems for each task to be fulfilled within the overall architecture defined in TISPAN NGN Release 1. There exist different subsystems for PSTN/ISDN emulation, streaming services and the 3GPP driven IP multimedia subsystem (IMS) which has been adapted to the NGN architecture. In NGN Release 2.0 IPTV shall be integrated into that architecture to support extended streaming services for next generation television. Current developments within ETSI TISPAN show two different approaches when speaking of the integration of IPTV services into the NGN: one IMS-based solution that relies on IMS/SIP signaling for new services and a non-IMS black box approach as an independent NGN subsystem. Our research activities are focused on the IMS-based activities and aim on the development of a reference architecture and on the service definition towards the now starting ETSI TISPAN standardization activities. This work shall introduce our architecture approach and evaluation based on precedent scenario and requirement analysis

Evolution of Next Generation Networks towards an Integrated Platform for IMS-Based IPTV Services

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 NextGeneration-Networks (NGN) towards future networks trends. Furthermore the Fixed-Mobile-Covergence (FMC) is presented and technology specific details are presented exemplarily.

Evolution of Telecommunication Services

The main objective of the next generation network (NGN) is enabling the provisioning of multimedia services over fixed and mobile networks with quality of service and mobile support, whereas the NGN framework leverages the IP Multimedia Subsystem an overlay control, which is standardized by 3 GPP. The NGN framework will enable new innovative multimedia services covering telephony and interactive multimedia services. Currently the ITU-T is working on standardizing an IPTV functional architecture for supporting TV services over NGN. This paper follows the IMS-based IPTV approach and proposes a converged end-to-end solution that enables the cross-fertilization of IMS services and IPTV services. Furthermore, the paper presents the Fraunhofer Institute FOKUS media interoperability lab (MIL), which is represented as a reference implementation of such framework as an open environment gathering all major IMS core and IPTV components as prototyping. Finally the paper presents the end-to-end signaling delay of an IPTV session setup and the performance measurement results of several IPTV application servers.

Cross-fertilization of IMS and IPTV services over NGN

Location-Aware applications for supporting the mobile user have proven significant relevance for future telecommunication and computing. The paper evaluates the outcome of the labs and the requirements of commercial usage. Based on the state-of-the-art analysis and the business view, a system architecture is proposed from the technical perspective. The required support of heterogeneous resources leads to the necessity of an adequate middleware platform. Merging data from different sources and constraints in the transmission and presentation capabilities of the mobile side require sophisticated media scaling and conversion capabilities. The envisaged service architecture leads finally to the discussion of the prototype developed on our Mobile Guide test-bed.
