Cognitive radio is viewed as a novel approach for improving the utilization of a precious natural resource: the radio electromagnetic spectrum. The cognitive radio, built on a software-defined radio, is defined as an intelligent wireless communication system that is aware of its environment
Joint Traffic Splitting and Spectrum Resource Allocation in Heterogeneous Cognitive Wireless Networks
"... Abstract — This paper investigates the resource allocation problem in heterogeneous cognitive wireless networks (HCWNs), with the objective of improving the end-to-end quality of service (QoS) performance for the communication session which is based on multiple radio access technologies (Multi-RATs) ..."

-RATs). The cognitive wireless networks (CWNs) share spectrum resource with primary users. The users with Multi-RATs applied transmit data through multiple paths by splitting the arrival packets to different access points in HCWNs. A mathematical model for minimizing the end-to-end delay with joint consideration
Radiosity and Realistic Image Synthesis
, 1993
"... this paper, such as the global distribution of radiative energy in the tree crowns, which affects the amount of light reaching the leaves and the local temperature of plant organs. The presented framework itself is also open to further research. To begin, the precise functional specification of the ..."

to available system resources in an optimal manner. A deeper understanding of the spectrum of processes taking place in the environment may lead to the design of a mini-language for environment specification. Analogous to the language of L-systems for plant specification, this mini-language would simplify
Emerging Technologies and Access to Spectrum Resources: the Case of Short-Range Systems (*)
"... Abstract: Traditional regulatory arrangements have constrained access to radio frequency spectrum. This has resulted in artificial scarcity of spectrum. The paper addresses the issue of whether technological developments in short-range systems (e.g. cognitive radios and ultra wideband) might promote ..."

Dual methods for nonconvex spectrum optimization of multicarrier systems
- IEEE TRANS. COMMUN
, 2006
"... The design and optimization of multicarrier communications systems often involve a maximization of the total throughput subject to system resource constraints. The optimization problem is numerically difficult to solve when the problem does not have a convexity structure. This paper makes progress ..."
