Multi-Objective Evolutionary Algorithms for Cognitive Radio Networks - Bog af Ayman A. El-Saleh - Paperback

Multi-Objective Evolutionary Algorithms for Cognitive Radio Networks - Bog af Ayman A. El-Saleh - Paperback

Joseph Mitola III: Cognitive radio is a decision-making layer at which ¿wireless personal digital assistants and the related networks were sufficiently computationally intelligent about radio resources, and related computer-to-computer communications, to detect user needs as a function of use context, and to provide radio resources and wireless services most appropriate to those needs¿ - Simon Haykin: ¿Cognitive radio is an intelligent wireless communication system that is aware of its surrounding..

Coordinated Interference Management for Multiple Access in LTE Network - Bog af Safa Essassi - Paperback

Coordinated Interference Management for Multiple Access in LTE Network - Bog af Safa Essassi - Paperback

In Long-Term Evolution (LTE) system, multi-access interference coordination has been planned to optimize the exploitation of radio resources, thus maximizing service quality, coverage and capacity. Many techniques aim to minimize inter-cell interference in LTE, such as fractional power control and spatial antenna techniques, including MIMO and SDMA. In LTE, the access technique rests on the OFDM modulation technique. The allocation of resources takes place both in time and frequency. These resources..

Laboratory Experiments in Astronomy for Undergraduate Students - Bog af Layali Y Salih Al-Mashhadani & Ahmed H Abdullah - Paperback

Laboratory Experiments in Astronomy for Undergraduate Students - Bog af Layali Y Salih Al-Mashhadani & Ahmed H Abdullah - Paperback

Computer technologies have been central to advances in astronomy and astrophysics since the last century and will play an important role in analyzing and interpreting more complex phenomena in the next decade. Many of the modern telescopes and observatories as the Very Large Array (VLA) of radio telescopes and the Einstein Observatory x-ray telescope created high-resolution astronomical images using computers as intermediaries between the telescope and the observer. In this manual book, we explain..

Novel Strategies to Improve Global Network Connectivity in MANETs - Bog af Alamgir Naushad - Paperback

Novel Strategies to Improve Global Network Connectivity in MANETs - Bog af Alamgir Naushad - Paperback

When a link between neighbouring node pairs is broken, an immediate operation is needed to restore the link by finding an alternative optimal path with minimal overhead in terms of the number of hops for data forwarding. The re-routing operation consumes battery power and other radio resources, sporadically. Re-routing is especially costly in networks without any fixed infrastructure since it frequently results in network flooding. Moreover, the transmission delay incurred as a result of re-routing..
