Emerging Internet Quality of Service (QoS) mechanisms are expected to enable wide spread use of real time services such as VoIP and videoconferencing. The "best effort" Internet delivery cannot be used for the new multimedia applications. New technologies and new standards are necessary to offer Quality of Service (QoS) for these multimedia applications. Therefore new communication architectures integrate mechanisms allowing guaranteed QoS services as well as high rate communications.
The service level agreement with a mobile Internet user is hard to satisfy, since there may not be enough resources available in some parts of the network the mobile user is moving into. The emerging Internet QoS architectures, differentiated services and integrated services, do not consider user mobility. QoS mechanisms enforce a differentiated sharing of bandwidth among services and users. Thus, there must be mechanisms available to identify traffic flows with different QoS parameters, and to make it possible to charge the users based on requested quality. The integration of fixed and mobile wireless access into IP networks presents a cost effective and efficient way to provide seamless end-to-end connectivity and ubiquitous access in a market where the demand for mobile Internet services has grown rapidly and predicted to generate billions of dollars in revenue. 
This tutorial covers to the issues of QoS provisioning in heterogeneous networks and Internet access over future wireless networks as well as ATM, MPLS, DiffServ, IntServ frameworks. It discusses the characteristics of the Internet, mobility and QoS provisioning in wireless and mobile IP networks. This tutorial also covers routing, security, baseline architecture of the inter-networking protocols and end to end traffic management issues.

The tutorial starts with some general aspects of modeling EMC modeling. The introduction ooutlines some commonly used analytical and numerical methods, respectively.
The participants will then be given a crash-course on the wire antenna theory and related numerical solution methods for the treatment of integral equations in both frequency and time domain. Some applications of these models related to dipole antennass, Yagi-Uda arrays and logarithmic-periodic dipole antennas (LPDA) will be presented.
In addition, full wave (antenna) models for several configurations of thin wires, from rather simple to realistic complex structures, followed by the analysis of overhead and buried lines, respectively, which will be carried out. The results obtained by using the rigorous full wave models will be compared to approximate transmission line (TL) approach. In particular, an attention will be focused to the analysis of PLC (Power Line Communications) configurations and modeling of lightning channel.
Then, the transient analysis of realistic grounding systems with particular emphasis to wind turbines will be carried out.
The last part of the tutorial deals with the assessment of human exposure to non-ionizing radiation. Low frequency, frequency and transient exposures will be covered. Finally, some biomedical applications of electromagnetic fields will be presented.

Multimedia communications is ubiquitous in today’s digital world. Communication over public networks is prone to well known security problems, such as data forgery, e.g., insertion or deletion of object into an image. One of the ways to protect against such attacks is to use standard cryptographic mechanisms such as message authentication codes (MAC). Such codes detect even minor modifications in the data they protect and thus enable the receiver to reject the falsified information. Due to the nature of the underlying transmission channels, multimedia data, such as text, audio or video, might be received in error. In certain cases, such as in uni-directional or real time communications, it is not possible to use networking protocols which guarantees data delivery using retransmissions. In order to be able to detect forgeries, but at the same time accept minor changes to the multimedia data (e.g., images), new cryptographic MACs are needed. Such new MACs should be able to tolerate minor unintentional modifications in the data and at the same time identify the intentional forgeries. These MACs can be based on the actual multimedia data or
on the features extracted from the original data. Such authentication algorithms can be called in general as the approximate or noise tolerant message authentication codes.
This tutorial focuses on the design of such message authentication algorithms. The first algorithm is based on image authentication using Noise Tolerant Message Authentication Codes (NTMAC) and feature extraction techniques based on Discrete Cosine Transform (DCT). An image is split into different blocks and each block is authenticated using the DCT of that block. Using a different permutation sequence increases or decreases the security of the proposed algorithm. The images are “approximate authenticated”, errors in the images are localized and a correctable number of errors are corrected using error correcting codes such as Turbo codes. An improved version of this algorithm is based on the concept of weights assigned to the important parts of the images, e.g., the DC component of the DCT of each block is more important than other (AC) components. The idea of approximate image authentication is further refined using standard Message Authentication Codes (MACs) combined with error correcting codes (Reed Solomon codes) and feature extraction based on the Discrete Wavelet Transform (DWT). The authentication tag is generated based on the encrypted encoded message and the MAC of the whole image. A certain number of errors are corrected using Reed Solomon codes before tag
verification and then the approximate authentication is performed.
These algorithms will be discussed together with their mathematical security analysis, to show their strengths and limitations.

Energy efficiency is increasingly becoming a key priority for Information and Communication Technology (ICT) organizations given the ecological and economic drivers. In this tutorial we will introduce and discuss a number of measures that can be used to reduce the power consumption in the Internet and will introduce methods for the optimum use of renewable energy in core networks to reduce the Internet’s carbon footprint at a given power consumption level. We will introduce network optimization through the use of mixed integer linear programming (MILP) giving a short tutorial on MILP and build on this and heuristics inspired by it to explore a number of energy and carbon footprint reduction measures including (i) Optimum use of time varying renewable energy in core networks; (ii) Optimum resource allocation and green network design with data centres; (iii) Dynamic energy-efficient content caching for video on demand, YouTube type content and IPTV (iv) Energy-efficiency through data compression; (v) Energy-efficient peer-to-peer content distribution (vi) Physical topology design considering operational and embodied energies. We finish by outlining future directions and open research issues. This tutorial will be of particular benefit to researchers and practicing engineers interested in energy efficient designs applied to the Internet and broadly.
