Applications of Game Theory and Microeconomics in Cognitive Radio and Femtocell Networks
(University of Waterloo, 2013-05-23)Cognitive radio networks have recently been proposed as a promising approach to overcome the serious problem of spectrum scarcity. Other emerging concept for innovative spectrum utilization is femtocells. Femtocells are ... -
Channel Allocation for Smooth Video Delivery over Cognitive Radio Networks
(University of Waterloo, 2010-08-30)Video applications normally demand stringent quality-of-service (QoS) for the high quality and smooth video playback at the receiver. Since the network is usually shared by multiple applications with diverse QoS requirements, ... -
Cognitive Spectrum Management in TV White Space: Libya as a Case Study
(University of Waterloo, 2014-12-12)The traditional spectrum allocation scheme is based on static allotment of frequency bands to applications and entities in specific geographical areas for extended periods of time. Telecommunications regulations, on the ... -
Cognitive-Empowered Femtocells: An Intelligent Paradigm of a Robust and Efficient Media Access
(University of Waterloo, 2010-09-22)Driven by both the need for ubiquitous wireless services and the stringent strain on radio spectrum faced in today's wireless communications, cognitive radio (CR) have been investigated as a promising solution to deploy ... -
Physical Layer Techniques for OFDM-Based Cognitive Radios
(University of Waterloo, 2014-02-18)Cognitive radio has recently been proposed as a promising approach for efficient utilization of radio spectrum. However, there are several challenges to be addressed across all layers of a cognitive radio system design, ... -
Throughput Scaling Laws in Point-to-Multipoint Cognitive Networks
(University of Waterloo, 2010-07-08)Simultaneous operation of different wireless applications in the same geographical region and the same frequency band gives rise to undesired interference issues. Since licensed (primary) applications have been granted ... -
Voice Capacity and Data Response Time in Cognitive Radio Networks
(University of Waterloo, 2013-05-22)The growing interest towards wireless communication services over the recent years has increased the demand for radio spectrum. Inefficient spectrum management together with the scarcity of the radio spectrum is a limiting ...
