Abstract:
Today, the radio spectrum is rarely fully utilized. This problem is valid in more domains, e.g., time, frequency and geographical location. To provide an efficient utilization of the radio spectrum, the Cognitive Radio Networks (CRNs) have been advanced. The key idea is to open up the licensed spectrum to unlicensed users, thus allowing them to use the so-called spectrum opportunities as long as they do not harmfully interfere with licensed users. An important focus is laid on the limitation of previously reported research efforts, which is due to the limited consideration of the problem of co

Abstract:
Cognitive radio networks (CRN) have been tipped as one of the most promising paradigms for next generation wireless communication, due primarily to its huge promise of mitigating the spectrum scarcity challenge. To help achieve this promise, CRN develop mechanisms that permit spectrum spaces to be allocated to, and used by more than one user, either simultaneously or opportunistically, under certain preconditions. However, because of various limitations associated with CRN, spectrum and other resources available for use in CRN are usually very scarce. Developing appropriate models that c

Operators worry not only about call quality and interconnect revenue loss, but also about network connectivity issues in areas where mobile network gateways are prevalent. Bandwidth quality as experienced by the end-user is equally important in helping operators to reduce churn.

Hasta ahora, generalmente son los usuarios los que eligen la tecnología a la que se van a conectar, ya sea configurando sus terminales o usando terminales distintos. Sin embargo, esta solución es incapaz de aprovechar al máximo todos los recursos. Para ello es necesario un nuevo conjunto de estrategias. Estas estrategias deben gestionar los recursos radioeléctrico

Abstract:
Long Term Evolution (LTE) is the Fourth Generation (4G) mobile broadband technology. Third-Generation Partnership Project (3GPP) has finalized its standardization in Release 8 technical specifications (R8). As users’ demand for higher data rate continues to rise, LTE and its ability to cost effectively provide fast, highly responsive mobile data services, a scalable bandwidth and a reduced latency will become ever more important. Nevertheless, The Evolved Packet Core (EPC) of the LTE is all-IP Packet-Switched (PS) core networks that lack a native support for Circuit-Switched (CS) services. Thi

Abstract:
Les nouveaux services de télécommunication accessibles en mobilité entraînent une demande croissante de débit et amènent aux limites de capacités des réseaux actuels. Pour répondre à cette demande, les opérateurs cellulaires déploient de nouvelles technologies et densifient leurs réseaux en ajoutant des petites cellules, où les stations de base sont plus proches des utilisateurs. Compte tenu de la visibilité directe et de la faible hauteur des antennes, le canal de propagation des petites cellules est différent de celui des macro-cellules et les modèles stochastiques de canal existants ne sont

2011/2012<br>The objective of this thesis is to discuss the performance achieved by IEEE 802.11 networks, considering in detail their simulation and experimental analysis, as well as the implementation aspects. The original contribution of this dissertation involves three main research fields within the context of distributed wireless networks: the experimental and theoretical analysis of IEEE 802.11e networks in presence of quality of service mechanisms, the development and the simulation of backward compatible medium access control protocols in presence of smart antenna systems, and, finall

Abstract:
The widespread availability of many emerging services enabled by the Internet of Things (IoT) paradigm passes through the capability to provide long-range connectivity to a massive number of things, overcoming the well-known issues of ad-hoc, short-range networks. This scenario entails a lot of challenges, ranging from the concerns about the radio access network efficiency to the threats about the security of IoT networks. In this thesis, we will focus on wireless communication standards for long-range IoT as well as on fundamental research outcomes about IoT networks. After investigating how

Abstract:
Fifth Generation (5G) cellular networks will experience a thousand-fold increase in data traffic with over 100 billion connected devices by 2020. In order to support this skyrocketing traffic demand, smaller base stations (BSs) are deployed to increase capacity. However, more BSs increase energy consumption which contributes to operational expenditure (OPEX) and CO2 emissions. Also, an introduction of a plethora of 5G applications running in the mobile devices cause a significant amount of energy consumption in the mobile devices. This thesis presents a novel framework for energy efficiency in
