Texte intégral

Résumé :

In a multicarrier communication system with known channel state information at transmitter (CSIT), it is well-known that the water-filling power allocation scheme is optimal in achieving the Shannon capacity. However, in a multicarrier broadcast network (e.g. over-the-air TV network) without CSIT, the optimal power allocation among subcarriers is still unknown, largely due to the heterogeneity of the channel conditions associated with different receivers. In the first part of the thesis, the performance of a generic multicarrier broadcast network is thoroughly studied by exploiting the frequen

Résumé :

In this thesis we provide a feasible solution for converging Machine to machine (M2M) networks and 3gpp Long Term Evolution advanced (LTE-A) Network. As a M2M network, a Wireless Sensor Network (WSN) is chosen. In order to overcome the power consumption restriction in M2M communication, IPv6 Low Power Personal Area Network (6LoWPAN) standard is used over IEEE 802.15.4 interface. A dual mode gateway structure is proposed for integration of two networks. One side of the gateway is connected to the M2M network, and the other side is the User Equipment (UE) which is the last node of LTE access lay

Résumé :

This thesis investigates different methods that can be used for analyzing network performance and,ultimately, can be used for measuring the convergence time of ring coupled networks. As of today,many networks are often run with extra links, serving as backup links in case any that of the mainlinks would go down. To operate networks with backup links in layer 2 and layer 3, specific re-routing protocols such as RIP and OSPF are used in order to calculate a feasible path through anetwork when a network state changes. Depending on different implementations of the protocolsand the hardware used, t

Résumé :

The networks in traditional data centers have remained unchanged for decades and have grown large, complex and costly. Many data centers have a general purpose Ethernet network and one or more additional specialized networks for storage or high performance low latency applications. Network convergence promises to lower the cost and complexity of the data center network by virtualizing the different networks onto a single wire. There is little evidence, aside from vendors' claims, that validate network convergence actually achieves these goals. This work defines a framework for creating a serie

Network Convergence or Divergence, what is it, and which are the most likely developments? Today, a much talked about area of telecommunications is the move toward the IP Multimedia Subsystem (IMS), and with it the introduction of IP-based communication in both Public Land Mobile Networks and Public Switched Telephony Networks. This thesis attempts to show whether these two networks will converge with each other and with the Internet in the future - based upon the existence of a few important prerequisites in terms of standards and protocols, whilst divergence in the networks could result if t

Résumé :

In this paper, we investigate the topology convergence problem for the gossip-based Gradient overlay network. In an overlay network where each node has a local utility value, a Gradient overlay network is characterized by the properties that each node has a set of neighbors containing higher utility values, such that paths of increasing utilities emerge in the network topology. The Gradient overlay network is built using gossiping and a preference function that samples from nodes using a uniform random peer sampling service. We analyze it using tools from matrix analysis, and we prove both the

As traffic congestion continues to worsen in large urban areas, solutions are urgently sought. However, transportation planning models, which estimate traffic volumes on transportation network links, are often unable to realistically consider travel time delays at intersections. Introducing signal controls in models often result in significant and unstable changes in network attributes, which, in turn, leads to instability of models. Ignoring the effect of delays at intersections makes the model output inaccurate and unable to predict travel time. To represent traffic conditions in a network m

Many questions of interest in various fields ranging from machine learning to computational biology and finance require the solution of an optimization problem.

First, the problem complexity pushes today's processors to their limits and the need for distributed algorithms arises quite naturally.

Résumé :

<p>The understanding of value is often described in terms of an industrial view in which value creation is linear, additive process. The emerging view takes a different approach to value creation: it’s interactive, relationships-based and synchronic. But either of these views capture fully the value creating importance of elements present especially in converging industries: coopetition, networks and external relationships. This thesis has been conducted by gathering primary data from telecommunication industry companies in forms of interviews. The studied companies are engaged in numerous dif

Résumé :

In this thesis the state of the art for IP networks and the two most predominant wireless access networks, UMTS and Wireless LANs, has been reviewed with respect to the enhancements required toward the objective of supporting services across different network technologies in a seamless manner. Three main areas of research were identified as key in the path toward All-IP networks: i) IP-based mobility management, ii) IP-based UMTS Radio Access Networks and iii) QoS for Wireless LANs.<br/><br/>Future All-IP networks require of an IP-based mobility management protocol to support mobility across h

Résumé :

Feedforward neural networks trained via supervised learning have proven to be successful in the field of pattern recognition. The most important feature of a pattern recognition technique is its ability to successfully classify future data. This is known as generalisation. A more practical aspect of pattern recognition methods is how quickly they can be trained and how reliably a good solution is found. Feedforward neural networks have been shown to provide good generali- sation on a variety of problems. A number of training techniques also exist that provide fast convergence. Two problems oft

Résumé :

This thesis deals with an optimization of Triple play services and security in optical access networks. The first chapter provides theory basics which are necessary for results evaluation. The second chapter describes optical access networks with their parameters such as transmission speed, split ratio, line code, bit error rate etc. defined by ITU. Next chapter summaries the current state in optical networks construction field according to the European Union developing plan. The practical part of this thesis is divided into several subchapters.

Résumé :

The advent and massification of the ICTs and the widespread use of internet have transformed the way in which traditional media such as ratio and television communicate with the audience, not only because of the technological shift itself, but because of the convergence culture undergoing as a result of the new relationships taking place online. Particularly, we wonder how the news’ organizations based in traditional media are adapting to these changes. Our assumption is that, although the news’ organizations have understood and are currently using the online technologies to present their in
