چکیده

Cognitive Radio (CR) is the future of radio systems giving authorities and end users unprecedented capabilities, and completely new services expectations. This paper aims at introducing an evolutionary novel Cognitive Radio adaptation engine architecture inspired from theories developed in cognitive sciences. Adaptation is a fundamental feature of CR necessary for many applications and use cases such as dynamic spectrum access, and emergency and disaster relief communication systems. The proposed architecture employs meta-heuristic techniques to dynamically and autonomously self-adapt to external varying stimuli, in order to reach some objectives. The implemented architecture is shown to be suitable for applications of emergency and disaster relief communication systems.

Architecture for an Open-source Cognitive Radio

OSCR, a framework for the implementation of a cognitive radio, is designed to facilitate the integration of a cognitive engine with one or more existing Software Communications Architecture (SCA) based radios. It consists of two components: a multiplexer, which acts as the cognitive engine’s point of control for each individual radio within the system, and an SCA resource within each radio, whi...

Meta-Heuristic based Adaptation Engine for Cognitive Radio Systems

Cognition is a high level mental faculty of the brain that includes functions like adaptation, learning, deciding, and others. Accordingly, a Cognitive Radio must have capabilities that mimic such Cognitive functions. As one of the fundamental cognitive abilities of the radio, this paper proposes a novel adaptation method; which uses Real-coded Genetic Algorithms (RGA) to adapt physical layer r...
