Joint Spatial and Spectrum Cooperation in Wireless Network.
(Queen Mary University of London, 2015-03)
The sky-rocketing growth of multimedia infotainment applications and broadband-hungry
mobile devices exacerbate the stringent demand for ultra high data rate and more spectrum resources. Along with it, the unbalanced ...
Radio Resource Management based on Genetic Algorithms for OFDMA Networks.
(Queen Mary University of London, 2012-01)
OFDMA will be the multiple access scheme for next generation networks, including LTE and LTE-A. These networks will provide higher data rates than now, up to several hundred Mbps.
These new networks, using a higher carrier ...
A Cross Layer Routing Protocol for OFDMA Based Mobile Ad Hoc Networks.
(Queen Mary University of London, 2013-05)
Mobile ad hoc networks are of growing interest because of their unique characteristics
and advantages in many practical applications. QoS provision acts as a major challenge
in the routing protocol design in the real-world ...
Threshold Setting Algorithms for Spectrum Sensing in Cognitive Radio Networks
(Queen Mary University of London, 2014-06)
As the demand for wireless communication services grows quickly, spectrum scarcity has
been on the rise sharply. In this context, cognitive radio (CR) is being viewed as a
new intelligent technology to solve the deficiency ...
Planning Simulation Run Length in Packet Queues in Communications Networks
(Queen Mary University of London, 2013-05)
Simulation is a technique of growing importance and is becoming an indispensable
tool applied in various academic industries, including packet networks.
Simulation provides an alternative research approach to implementing ...
Wireless Links for Telecare and Telemedicine Applications using Compact Body-Worn Antennas.
(Queen Mary University of London, 2013-06)
This thesis concerns the design of body-centric wireless communications for short-range indoor Telecare/Telemedicine applications. Such communications are starting to be used to convey key, relatively low data-rate body-sensor ...
A cross-layer cooperation strategy for cellular networks.
(Queen Mary University of London, 2013-09)
Cooperation is seen as a means to improve the signal in OFDMA wireless networks by overcoming the inter-cell interference. Such co-operation can be deployed in both the physical layer and the MAC layer. In this thesis, a ...
Experimental Characterisation of Body-Centric Radio Channels Using Wireless Sensors
(Queen Mary University of London, 2012-10)
Wireless sensors and their applications have become increasingly attractive for industry, building automation and energy control, paving the way for new applications of sensor networks which go well beyond traditional ...
Indoor and Outdoor Location Estimation in Large Areas Using Received Signal Strength
(Queen Mary University of London, 2013-07)
Location estimation when deployed on wireless networks supports a range of services
including user tracking and monitoring, health care support and push and pull marketing.
The main subject of this thesis is improving ...
Energy Efficient Packet Size Optimization for Wireless Ad Hoc Networks
(Queen Mary University of London, 2014-03-02)
Energy efficiency is crucial for ad hoc networks because of limited energy stored in the battery. Recharging the nodes frequently is sometimes not possible. Therefore, proper energy utilization is paramount. One possible ...
