Current methods of training such maps (e.g. self organizing maps-SOM, generative topographic maps) require centralized control and synchronous execution, which restricts scalability. We present an algorithm that uses N autonomous units to generate a feature map by distributed asynchronous training. Unit autonomy is achieved by sparse interaction in time & space through the combination of a distributed heuristic search, and a cascade-driven weight updating scheme governed by two rules: a unit i) adapts when it receives either a sample, or the weight vector of a neighbor, and ii) broadcasts its weight vector to its neighbors after adapting for a predefined number of times. Thus, a vector update can trigger an avalanche of adaptation. We map avalanching to a statistical mechanics model, which allows us to parametrize the statistical properties of cascading. Using MNIST, we empirically investigate the effect of the heuristic search accuracy and the cascade parameters on map quality. We also provide empirical evidence that algorithm complexity scales at most linearly with system size N. The proposed approach is found to perform comparably with similar methods in classification tasks across multiple datasets.

G-Lab 2 is a research project for Future Internet Architecture (FIA), which focuses on problems of the Internet such as rigidness, mobility, and addressing. Where the focus of ICSY 3 was on providing the flexibility [Mue13] in future network architectures. An approach so-called Service Oriented Network Architecture (SONATE) [KSMB14]) is proposed to compose the protocols dynamically. SONATE is based on principles of the service-oriented architecture (SOA) [Erl08], where protocols are decomposed in software modules and later they are put together on demand to provide the desired service. This composition of functionalities can be performed at various time-epochs (e.g., run-time, design-time, deployment-time). However, these epochs have trade-off in terms of the time-complexity (i.e., required setup time) [Bas80] and the provided flexibility. The design-time is the least time critical in comparison to other time phases, which makes it possible to utilize human-analytical capability. However, the design-time lacks the real-time knowledge of requirements and network conditions, what results in inflexible protocol graphs, and they cannot be changed at later stages on changing requirements. Contrary to the design-time, the run-time is most time critical where an application is waiting for a connection to be established, but at the same time it has maximum information to generate a protocol graph suitable to the given requirements. Considering limitations above of different time-phases, in this thesis, a novel intermediate functional composition approach (i.e., Template-Based Composition) has been presented to generate requirements aware protocol graphs. The template-based composition splits the composition process across different time-phases to exploit the less time critical nature and human-analytical availability of the design-time, ability to instantaneously deploy new functionalities of the deployment time and maximum information availability of the run-time. The approach is successfully implemented (i.e.,A.6), demonstrated (i.e., [GSS + 12]) and evaluated (i.e.,6) based on its performance to know the implications for the practical use.

This article describes how the principles of Service Oriented Architecture (SOA) can be employed to develop a flexible network architecture. The prototype of the concept has been developed and demonstrated in the EuroView 2012 workshop. We showed that the SOA paradigm can be applied to networks by utilizing the concepts of self-contained building blocks, dynamic protocol graphs (PGs) and functional composition (FC) methods. We demonstrated that both short-term flexibility (i.e., networks are adapted based on application requirements) and long-term flexibility (i.e., networks can be evolved) can be achieved by using the architecture.

Since then the whole Internet came to existence and with it a single protocol stack: TCP/IP. What was a good solution back then, is no longer appropriate to fulfill the emerging demands of applications. Newer protocols have been created as solutions for the problems, but replacing TCP/IP requires a complicated deployment and migration phase. The problems with the current Internet architecture and its fixed structure have triggered a discussion on a Future Internet architecture. We propose a way to dynamically select and compose protocols based on principles of service oriented architectures. The goal is a network architecture where new protocols could be easily added and are automatically and transparently used by applications. In this paper we present a way to describe protocols and their effects and dependencies between them. We also present a method to select and compose protocols. 1. Note: SOA is a paradigm, and thus it does not rely on a specific technology (e.g. Web Services) and is not limited to specific application areas (e.g. enterprise information integration).

The composition of functionalities to achieve a desired result can be performed at various time-phases (e.g. run-time, design-time, deployment-time), but it is not clear which phase is the most suitable one in terms of performance, complexity and flexibility. It is most likely that a single approach will not be appropriate in every circumstance. In this paper, an intermediate approach so called template based composition is proposed to find a compromise between complexity and flexibility.

Ubiquitous use of smart mobile devices enables gathering of personalized data enriched with contextual information. This information can ideally be used in modern eHealth scenarios, resulting in mobile health (mHealth) scenarios. This paper describes how highly personalized and sensitive information, such as vital signs enriched with contextual information of a patient, can be stored at mobile devices and provided via modern web technologies for later-on analysis and health monitoring. Therefore, this paper presents a number of different scenarios in which such mobile technology provides certain benefits, discusses benefits, drawbacks and challenges of such an approach and describes an example implementation of an mHealth scenario.

Coupling between applications and underlying protocols makes it almost impossible to change one without changing the other. Coupling can be loosened or resolved by not involving applications in protocols implementation details but, only in functionality necessary to establish a communication. This way underlying network can deploy novel or updated implementations of a functionality without needing to change the applications. Using intermediate abstraction layers is an approach to break the dependency between applications and network protocols. One of the major goals in future internet architectures is to be flexible enough to adapt to application’s requirements. In this paper, a requirement-based API is presented as an abstraction layer to make applications independent of network mechanisms, which also helps in the transition to future internet architectures.

Since then, more and more areas of our daily live are reached by the evolving Internet including business critical areas, causes through its big success, fast acceptance and emerged possibilities. However, today's best-effort Internet still lacks wide-area support for End-to-End Quality-of-Service and security sensitive services. Future Internet (FI) related research targets at a redesigns of the current Internet while addressing today's requirements. In this paper we present a clean-slate cross-layer FI architecture approach. In order to optimize the underlying network for services we focus on a framework able to provide service required functionalities at the network layer on demand. We validate the presented architecture based on a prototype implementation. An evaluation section discusses measurements done with the prototype and an outlook on our future work concludes the paper.

In the future, it is expected that networks will offer a large number of different communication services. With so many services available, determining which service to select and use becomes much more difficult. Here we propose a description schema including an ontology for describing communication services. For service selection a decision making process called Analytic Hierarchy Process (AHP) is utilized which is specially adapted and extended for automatic processing.

So far, it has been presumed that global interaction of agents is necessary for this process. We establish that this is not the case, and that global topology can be uncovered through strictly local interactions. Enforcing uniformity of map quality across all agents, results in an algorithm that is able to consistently uncover the global topology of diversely challenging datasets.The applicability and scalability of this approach is further tested on a large point cloud dataset, revealing a linear relation between map training time and size. The presented work not only reduces algorithmic complexity but also constitutes first step towards a distributed self organizing map.

This article describes how the principles of Service Oriented Architecture (SOA) can help to develop more flexible network architecture. We argue that the SOA paradigm can be applied to networks by utilizing the concepts of self-contained building blocks, dynamic protocol graphs and selection and composition methods. In order to make use of flexible networks, applications must be decoupled from the protocols they use. We give a brief overview, of how some of these concepts are already implemented, by presenting few approaches. Finally we describe some challenges of service oriented network architecture.

Disruption or natural disaster scenarios can not be tested on the physical systems, thus simulations are used for experimentation on CIs and as they are inherently distributed and interdependent which is why here, to model CIs, we use a distributed simulations standard namely High Level Architecture (HLA). The main goals of HLA are to provide interoperability and flexibility. Security and events logging are neither included nor emphasis of HLA standard. This paper presents a framework to have a supervised and secure messages exchange across distributed simulations using HLA standard.
