Cognitive Infocommunications

Peter Baranyi

3D Internet Based Control and Communications Laboratory, Hungary

Abstract Cognitive infocommunications (CogInfoCom) is a newly emerging research field which investigates the link between the research areas of infocommunications and cognitive sciences, as well as the various engineering applications which have emerged as the synergic combination of these sciences. The primary goal of CogInfoCom is to provide a systematic view of how cognitive processes can co-evolve with infocommunications devices so that the capabilities of the human brain may not only be extended through these devices, irrespective of geographical distance, but may also interact with the capabilities of any artificially cognitive system. This merging and extension of cognitive capabilities is targeted towards engineering applications in which artificial and/or natural cognitive systems are enabled to work together more effectively.
The complexity of the cognitive processes involved in our interaction with the devices we use for infocommunication is rapidly changing. This is true both in terms of the quantity and quality of information that is communicated between the user and the infocommunication system. Thus, while earlier use case scenerios such as telephone communication exclusively involved the modalities of speech and audition, newer technologies (such as 3D virtual collaboration, smart personal information devices, body sensor networks, and human interaction-related aspects of future internet technologies) require the parallel use of a large variety of sensory modalities such as gestural, facial, haptic and visual communication. Further, it is becoming a natural requirement for users to communicate with entities which do not exist in a natural environment, such as databases, spatial memories, and other immaterial abstractions. In order to accomodate such use case scenarios, it is becoming necessary to exploit the plasticity of the human brain so that the cognitive infocommunication channels which link the user's and the device's cognitive processes can be synthesized and manipulated on demand.

Peter Baranyi received his M.Sc. / Ph.D. and habilitation at the Budapest University of Technology and Economics (BME) in 1995 / 1999. and 2007, and D.Sc. at the Hungarian Academy of Sciences in 2006. He is a professor at BME and the head of the 3DICC (3D Internet based Control and Communications) laboratory that was established in the consortium of BME and the Computer and Automation Research Institute (MTA SZTAKI). His research interest focuses on Cognitive Infocommunication and System Control design methodologies.

Tale of the random, the guided and the maximum likelihood: Bio-inspired optimazitaion in wireless communications ...

Lajos Hanzo

School of ECS, University of Southampton, UK

Abstract Following a light-hearted introduction to the evolution of wireless communications, a digest of a range of challenging large-dimensional optimization problems is provided. Typical examples can be found in the optimization of wireless networking solutions aiming for minimizing the interference imposed on other communicating users, whilst minimizing the entire network's power consumption. Another demanding problem is the simultaneous optimization of the received signal's quality for a multiplicity of communicating subscribers. In these potentially NP-hard problems it is typically unrealistic to carry out a maximumlikelihood- style full search, but this problem may be circumvented with the aid of bio-isnpired random guided optimization techniques, which are capable of "capturing the maximum-likelihood solution with a high probability,whilst estricting the search to a tiny fraction of the entire searchspace"...

- This lecture will define a number of challenging objective functions (OFs) in the context of sophisticated MIMO multi-user detection (MUD) and multi-user transmission (MUT) as well as networking problems;
- Then a number of genetically inspired optimization tools will be highlighted, such as Genetic Algorithms (GA), Ant Colonies (ACO), Particle Swarm Optimization PSO), Harmony Search (HS), Differential Evolution (DE) etc in order to design solutions capable of approaching the optimum performance at a fraction of the full-search-based complexity. Our goal is that of approaching the optima of the abovementionedOFs by exploiting the power of these techniques for the holistic optimization of sophisticated wireless systems...

European Future Internet - an opportunity or a necessarity

Boris Moltchanov

Mobile Services Innovation Manager, Telecom Italia, Italy

Abstract European research currently focused into innovative services able to support some strategic priority technological areas such as eHealth, SmartCities, elderly people support, social networking, etc. in order to sustain the competition with US companies invaded the world. This is truth for both the academic and industrial innovation sector. As a main result of this cooperation a huge initiative called Public Private Partnership has been created and sponsored by European Commission. Many big European industrial companies are part of this initiative and are participating in a several integration projects aimed to create so called Future Internet platform and services designed for and running in this platform. The main Future Internet platform project is FI-WARE, while there are few smaller Usage Areas project such as e.g. FI-CONTENT addressing certain application domain, multimedia content management in the last case.
Telecom Italia is one of the PPP partners and is involved into this research and integration. The speech is addressed to both the PPP Future Internet initiative and the Telecom Italia's effort within it, including FI-WARE and a couple of other projects for supporting of this initiative.

Content Delivery Networking: Modeling, Optimization and Survivability

Krzysztof Walkowiak

Wroclaw University of Technology, Poland

Abstract Recently, we can observe a growing popularity of networking approaches developed to deliver various kinds of content, e.g., Peer-to-Peer (P2P) systems, Content Delivery Networks (CDNs), video streaming, web caching. This trend follows mainly from the fact that due to the increasing number of Internet users and still emerging new network services, there is a need to facilitate distribution of popular content in the Internet. For instance, Cisco forecasts that by 2014 more than 90 percent of the traffic in the Internet will be video content whether distributed using P2P or streamed from servers. The most popular global CDN system is Akamai that delivers between 15-30% of all Web traffic using 84,000 servers in 72 countries. The daily Web traffic provided by Akamai reaches more than 5 Terabits per second and hundreds of billions of Internet interactions. The major assumption of content delivery networking systems is that the same content is replicated over many locations in the network. Therefore, anycasting - defined as a one-to-one-of-many technique - is perceived as a natural transmission technique for content networking. Apparently, also unicast transmission - defined as one-to-one - provides sufficient framework for delivering of replicated content over the network. However, anycasting can significantly improve the network performance in terms of various network metrics, especially network survivability. This talk will discuss a number of issues related to content delivery networking with a special focus on modeling, optimization and survivability aspects.

The road to a new optical network: How to solve bandwidth limitations

Szilard Zsigmond

Alcatel-Lucent, Austria

Abstract The ever-increasing bandwidth hungry application triggers an unexpected transformation in telecommunication networks. This has influence in all the layers of the network and it is clear that the highest impacted one is the L0, the WDM network. The evolution of the optical networks from a static point-to-point to a more dynamic ROADM network has already been done in most of the networks. The integration of OTN switching (L1) into WDM is happening right now. Considering protection and/or restoration a more clever control plane (GMPLS) has been proposed. The benefits are the photonic or ODU level restoration mechanisms. All these features will end up in better resource utilization but this is still not enough. As it happened in the past the channel bitrates as well as the total number of channels per optical fiber keep increasing. The introduction of coherent transmission at 40G/100G is on of the milestones in solving the capacity restriction of the service providers. This talk will address all the mentioned problems and will try to propose solutions highlighting their benefits and their limitations.
