Yunpeng (82 Ergebnisse)

Softcover. Zustand: As New. Leichte Kratzer / Abnutzungen / Druckstellen. J'aime le jazz. Je danse, vacillant, sur une musique instable et sans harmonie, comme s'il s'agissait de courir vers un point ultime selon une suite infinie de décimales périodiques. Mes partitions, ce sont les bars, les avenues, les chambres simples et rudimentaires des petites gens, les gares, ma région natale, Dostoïevski, Brodsky, Kierkegaard, Kafka, sur lesquels je danse et titube. Et si les vents nettoient mes poches, mon âme aveugle est plus libre. Musicien, poète, vagabond, Zhou Yunpeng partage avec nous une nuit de lecture, un morceau de chanson, un bout de chemin. Avoir perdu la vue à l'âge de neuf ans ne l'a pas dissuadé de courir les routes de Chine, pinçant les cordes de sa guitare et fredonnant par les rues des ballades à la mémoire des opprimés, des talents affamés, des amoureux de l'art et du vin. C'est ainsi qu'il gagne sa vie, et sa voix est unique. Il faut l'écouter, fière et lumineuse, dans le tumulte et la paix mêlés. Avec le temps et l'alcool, nous pilonnons chaque vers, et certains deviennent si solides que vous pourriez en bâtir vos demeures.…

Paperback. Zustand: New. This thesis studies the congestion problem at the Medium Access Control (MAC) layer of the IEEE 802.11p system in highway scenarios using an analytical approach. Using the Carrier Sense Multiple Access/Collision Avoidance (CSMA/CA) protocol, the IEEE 802.11p system suffers from the hidden station problem. This thesis provides formal definitions for the hidden station condition and the hidden station problem and develops an analytical methodology for CSMA protocols to investigate the interaction between stations in mutual channel sensing range and hidden to each other. Analytical models are developed for broadcast communication using the generic CSMA protocol and the IEEE 802.11p MAC protocol with a one-dimensional (1-D) homogeneous network topology. Simulation studies prove the accuracy of the models in analyzing the reliability performance and the efficiency performance of CSMA broadcast communication with hidden stations.The performance of Cooperative Awareness Message (CAM) in IEEE 802.11p network is analyzed for highway scenarios using the developed analytical models. The study reveals that in a hidden station scenario the reliability performance of the CAM broadcast communication deteriorates with increased topological distance between the transmitter and the receiver. This study provides quantitative analysis of this performance with respect to network density, frame length, traffic load and settings of the IEEE 802.11p MAC protocol. Analysis of the mean update interval of CAM at a receiver vehicle discovers though in general the performance degrades with increased network density, the update interval of CAM frames from a particular vehicle in the vicinity of the receiver, e.g. with a topological distance less than 8 between the transmitter and the receiver, can be easily maintained below 1 second by using control mechanisms like transmit power control, transmit rate control and link control. The analytical models developed in this work provide quantitative guidance on optimizing protocol parameters and utilization of these control mechanisms.…
