Content Distribution for Mobile Devices

cracking the gre 2013 edition mdbg chinese reader 6 crack With the advent of hand held devices wireless networks are struggling to deliver all the traffic that is demanded by mobile users. Future wireless networks are likely to be ultra-dense networks formed by a large number small-cell base station with small coverage areas. Due to practical and cost-related limitations small-cells are connected to the core network through a low capacity backhaul link, which can jeopardize the capacity of the whole wireless network.
altera dsp builder crack We investigate techniques and algorithms for pushing popular content close to the mobile users, that is, caching popular content at the network edges (i.e, in small-cell base stations) in order to reduce delay and alleviate congestion in the backhaul link of these small-cell base stations.
pan fry crackling Our research focuses into two areas: 1) fundamental limits of content caching by using tools from information theory and coding, and 2) practical algorithms for content caching: by using techniques from multi-armed bandit problems we design algorithms that learn the popularity profile while optimising the cache content.

Cyber-security and Privacy

motorcycle cooler rack trailer minecraft cracked launcher 1.6.4 download free Information and communication technologies are extremely integrated into our everyday environment. Embedded computers and networks monitor and control physical processes, actuators and sensors, and there are generally feed-back loops through which the physical world infuences the digital one and vice versa. Such interconnected systems are known as cyber-physical systems (CPSs). They bring many advantages, like energy savings, reduced operational and consumption costs, improved reliability. However, they collect and spread a massive amount of users' information. photoshop crack cs5 64 bits Thus, CPSs raise the issue of data security and especially privacy, since they may lead to the exposure of private details of our daily lives.
crack head of gayle creek In our research group we study the theoretical limits of privacy-preserving techniques and we try to improve them. We focus on smart grids and we consider the presence of an energy harvester in the system in order to mask the real users' energy consumptions.

Energy Harvesting Wireless Communications

counter strike 1.6 crack free download free download aircrack for windows 7 We investigate communications protocols for energy harvesting wireless networks. Our research focuses on the design of communication strategies that make an intelligent use of the available energy at the wireless nodes in order to guarantee exceptional communication performance.
crack einfach tierisch Our research covers three major areas, which depend on the amount of information about the energy availability at the node, namely 1) offline optimization (predictable energy availability), 2) online optimization (energy availability is random and its distribution is known, 3) learning optimization (energy availability is random and its distribution has to be learn). We study communication for a number of communication system topologies, such as relay communications, multi-access channel communication, as well as point-to-point with energy harvesting.
activate office 2010 xp crack We use techniques coming from Machine Learning and Operations research such as Reinforcement Learning and Multi-armed bandit optimization for the communication strategy design and node operation.

Joint Source Channel Coding

pdf watermark remover 1.0.1 keygen tally erp crack Tmetastock 12 crack free download he optimality of the source channel separation theorem does not generalize to multi user communication systems, but madrix led software crack for a few special cases. So, for general problems like lossy transmission of the sources over multiuser networks, we have tai game kim c ng crack to optimize the source and channel coding jointly. Similarly, even in some point to point wireless communication scenarios, nips crackers in which the exact value of the signal-to-noise ratio (SNR) at the receiver is not known at the transmitter, source channel telecharger le film ma 6t va cracker gratuit separation theorem fails. In these scenarios, the transmitter might only know a range of SNRs at the receiver and tries to send what does tyga say in the beginning of rack city the information such that the receiver reconstructs the source signal with the minimum possible end-to-end distortion. Generally, mobile spy cracked apk there are two ways of designing such a system: i) using analog transmission methods, and ii) using digital transmission methods. crack top eleven sur iphone Analog transmission methods provide gradual quality degradation of the received signal with the decreasing SNR. However, crack wifi xubuntu these systems are in general suboptimal, in the sense that, they rarely achieve the optimal theoretical bounds. On the other hand, alien skin eye candy crack digital system are not only easy to implement, but they can be designed to asymptotically achieve the theoretically optimal windows 8 activation crack download performance. Unfortunately, digital systems suffer from threshold effect, meaning that when the SNR of the channel output the sims 3 crack peb.pl is lower than the designed SNR, receiver fails to decode the information, and when the channel output SNR is higher than the download spb shell 3d with crack designed SNR, the quality of the decoded information does not improve. sleeping dogs 1.8 crack fix skidrow An important practical application area for JSCC, is wireless sensor networks (WSN).
