Efficient Media Access Protocols for Wireless LANs with Smart Antennas
(2003)
The use of smart antennas in extending coverage range and capacity of wireless networks dictates the employment of novel media access control protocols, with which the base station (BS) or access point (AP) provides access ...
Channel State-Adaptive Techniques for Throughput Enhancement in Wireless Broadband Networks
(2002)
Wireless broadband access is becoming increasingly popular in the telecommunications market due to the projected demand for flexible and easily deployable high-speed connections. In order to adhere to the volatility of the ...
Dynamic Code Assignment and Spreading Gain Adaptation in Synchronous CDMA Wireless Networks
(2002)
DS-CDMA has been recognized as the major candidate for providing high and variable data rates in third generation wireless networks, where multi-code structures and different spreading gains will be employed. In this paper, ...
Next Generation Satellite Systems for Aeronautical Communications
(2000)
The US airspace is reaching its capacity with the current Air Traffic Control system and a number of flights that is constantly rising, and estimated to be over 54 million per year by 2002. The FAA has undertaken several ...
A Framework for Cross-layer Design of Energy-efficient Communication with QoS Provisioning in Multi-hop Wireless Networks
