Abstract: In recent years, the development of intellectual, adaptive wireless devices termed cognitive radios, composed with the introduction of secondary spectrum licensing, has led to a new hypothesis in transportations: cognitive networks. Cognitive networks are wireless networks that consist of several types of users: often a primary user (the primary license-holder of a spectrum band) and secondary users (cognitive radios). These cognitive users employ their cognitive abilities to communicate without spoiling the primary users. The study of cognitive networks is comparatively new and many queries are yet to be responded. In this article we best part some of the recent information theoretic limits, models, and design of these auspicious networks.
