T01 - Tutorial Title:    Peer-to-Peer Networks - Application and Performance Issues

Presenter:    Kurt Tutschku, Assistant Professor, University of Wuerzburg,Germany 

Abstract:   Peer-to-Peer (P2P) networks and P2P content distribution applications have become very popular lately, as witnessed by the relentless spread of file sharing applications like eDonkey and BitTorrent. Latest observations reveal that P2P applications have even surpassed the World Wide Web (WWW) in popularity, at least in terms of traffic volume in provider networks. However, P2P is not only restricted to file-sharing. It may also comprise the use of self-organizing P2P mechanisms for network control. The efficiency of such a mechanism was just recently demonstrated in a way impressive by the P2P VoIP application Skype.

The aim of this tutorial is to give an overview on P2P and to provide insights into the performance and applicability of P2P mechanisms in networks for content distribution and network control. Resource locating via Chord, Kademlia and Mobile P2P file-sharing are selected as examples for investigating carrier-gradeness of P2P.

The tutorial will explain what is understood by P2P, how P2P networks operate, and how efficient P2P systems are. Therefore, we will first provide an overview of the landscape of P2P protocols and applications, outline their aims and describes the basic terminology. Then, we will discuss thoroughly and evaluate P2P algorithms for the searching of content/ resources. After that, we focus on P2P mechanisms for content distribution. We explain selected algorithms and assess their performance. The tutorial is concluded by a summary and an outlook on future developments.

T05 - Tutorial Title: Power Line Communications 

Presenter:    Dr. Stefano Galli, Senior Scientist at Telcordia Technologies 

Abstract:     Home networking transcends simple data or Internet access sharing among multiple PCs so that today much attention is devoted to those technologies that will enable multimedia support within the home. Today, however, technology is not mature enough to provide ubiquitous wireless home-networking solutions with truly multimedia capability at a mass market price. Thus, it is reasonable to assume that both wired and wireless solutions will coexist for some time and will take care of different sets of applications. Among the several wired alternatives, home networks based on PLCs promise a truly ubiquitous networking solution. Therefore, the topic of PLCs is very relevant to the consumer electronics industry.

The goal of the proposed tutorial is to give a good understanding of the main issues related to power line communications (PLCs). The tutorial will start by reviewing the major applications of PLCs (access, in-home, in-vehicle, smart grid, etc.), and pointing out world trends and market status. Moreover, a brief overview of standardization and PLC industry associations will be given. The course will continue addressing the existing channel models, with particular reference to recent results. Finally, the suitability of modulation and coding techniques for the power line channel will be reviewed.

The topic of PLCs is a very interdisciplinary one so it is impossible to give an in-depth course on it in a half-day tutorial. The course, however, will give a rather complete overview of the major issues related to PLCs

T06 - Tutorial Title:    Autonomic Wireless Networks in Smart Environments 

Presenter:     Antonio A. F. Loureiro, Department of Computer Science, Federal University of Minas Gerais, Brazil 

Linnyer B. Ruiz, Department of Electrical Engineering, Federal University of Minas Gerais, Brazil 

Abstract:    Autonomic Computing defines computational systems that are able to manage themselves with none or minimal human intervention. The implementation of the concepts related to autonomic computing in computer networks leads to the development of a new concept: autonomic networks. This kind of network is able to perform self management of its elements and data communication links. The goal is to have network services and functions performed without the involvement of a human manager and in a transparent way to its users. Besides, the network should be able to learn from the actions performed by its elements and the analysis of all acquired results. The automatic execution of tasks and the learning possibility characterize the autonomic aspect of this kind of network.

Smart environments represent the next evolutionary development step in building, utilities, industrial, home, shipboard, and transportation systems automation. In those scenarios, wireless transmission is complex and often problematic, where a number of conditions such as multipath interference, transmission collisions, and obstructions adversely impact the reliability, scalability and data throughput of high bandwidth communications. In addition, the vast majority of applications and services for those scenarios were initially designed to run on wired networks, and thus require considerable technology adaptation for wireless implementation. Furthermore, in order to ensure widespread adoption, the wireless modules deployed must fit into the cost constraints of their environments. To cope with those design challenges, in the future, we can expect to have those networks to work in an autonomic way.
