Video technologies including ultra-highdefinition TV (more than 33M pixels) continue to advance and future communication networks will become videocentric. The inefficiencies of current IP technologies, in particular the energy consumption and throughput limitations of IP routers, will become pressing problems. Harnessing the full power of light will resolve these problems and spur the creation of future video-centric networks. Extension of optical layer technologies and coordination with new transport protocols will be critical, and are discussed in detail.

The influence of the supervision methods on the differential loss of the OXC is studied. Experiments demonstrate that an alarm can be sent out immediately by the supervision circuit when errors occur in the optical switches. Guard time protection is introduced to the supervision circuits to prevent them from sending an alarm by mistake. These supervision schemes can be used in the optical layer management for fault detection and network restoration

Normally the fusion network is in parallel configuration and the conventional fusion rules are the k out of N rules because of their simplicity to manage. When the detection nodes are similar with each other i.e.

The first is to maximize the channel capacity over the given frequency band, which is detected usable for CR systems. The second is the out-of-band interference suppression of the CR systems.

It is a linear combination of orthogonal modified Hermite pulses, which have unique advantages. The proposed pulses are orthogonal to each other and they can fit to the UWB spectrum mask. They occupy the most possibly similar frequency bands, which maximums the efficiency of spectra. They are applied to a parallel UWB synchronization approach, which takes use of parallel correlator to estimate the propagation delay. It can significantly shorten the processing time. Performance is investigated through the evaluation of mean-squared channel error for an AWGN channel and UWB indoor channel issued by IEEE 802.15.3a. It is observed that the parallel approach based on CMHP performs better than general method of synchronization.

In traditional method, variance of received signal is imposed to make the identification and mitigation of NLOS error. Taking into account the random distribution of obstacles, this paper presents a localization method in UWB environment based on signal statistics. The impact factor and scale factor are defined in order to describe the complex characteristics of the channel and to make the ranging more accurate in the proposed method. Simulation results show that the precision of localization can be improved significantly.

On the one hand, secondary users must be aware of the interference caused to primary users. Therefore, cognitive radio network should control their transmission power. On the other hand, the interference from primary network may degrade the performance of cognitive network. This paper

These networks act as backbones for optical line terminators (OLT) or electronic switches that serve optical access networks. For reasons of economy they are typically constructed as unidirectional rings or busses. Well-known optical time and wavelength division networks and hybrid versions following the photonic slot routing principle are introduced and compared. All of the architectures shown here perform some kind of carrier sensing to avoid collisions in a de-centralized way. We give approximations of the expectable gain of dynamic channel sharing over static assignment and the tuning time penalty. Technological limitations and cost driving factors are analyzed with respect to a low-cost implementation of a dynamic traffic aggregation.
