—Optical communication through the atmosphere possibly enables high data rate communication. However, the optical field undergoes fades or outages due to air turbulence. Spatial ...
— Cognitive radio has been recently proposed as a promising technology to improve the spectrum utilization efficiency by intelligently sensing and accessing some vacant bands of...
— The CSMA/CA protocols are designed under the assumption that all participant nodes would abide to the protocol rules. This is of particular importance in distributed protocols ...
With the advent of cognitive radio technology, new paradigms for spectrum access can achieve near-optimal spectrum utilisation by letting each user sense and utilise available s...

— Content Delivery Overlays improves end-user performance by replicating Web contents on a group of geographically distributed sites interconnected over the Internet. However, wi...
— The main task in OFDM downlink scheduling design is to maximize some kind of utility considering user specific as well as system induced constraints. A typical example is the ...
Abstract— In this paper, the performance of a downlink synchronous MC-CDMA system with joint frequency-time domain spreading over time-variant frequency-selective Rayleigh fading...
— Many network operators offer some type of tiered service, in which users may select only from a small set of service levels (tiers). In this work, we study the problem of desig...
