An Approach for Spectrum Allocation for Maximized Coverage in Cognitive Radio Network
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 3
Abstract
Cognitive Radio Network (CRN) has emerged as a promising technology to exploit the unused portions of spectrum in an effective manner. The fixed spectrum allocation is used to refer the unused portions of spectrum are called as ‘spectrum holes’. Cognitive Radio network detect this type of issue and also it, allowing devices to sense the spectrum for unused portions and use the most suitable ones.Cognitive radio networks is the next generation of the key enabling technology that enables dynamic spectrum access .The spectrum allocation is one of the most important issues in CRNs. The main objective is to satisfying the interference constraints, and to maximize node connectivity after spectrum allocation, which is important for packet delivery in an effective communication. The main objective is to provide spectrum resources effectively to the users in the network. To design node based selection and link based selection algorithms and an node link based algorithm are used to improve the spectrum utilization for effective transmission.
