Optimal energy-delay tradeoff for opportunistic spectrum access in cognitive radio networks
Cognitive radio (CR) has been considered as a promising technology to enhance spectrum efficiency via opportunistic transmission at link level. Basic CR features allow secondary users to transmit only when the licensed channel is not occupied by primary users. However, waiting for idle time slot may include large packet delay and high energy consumption. Thus, we consider Opportunistic Spectrum...
متن کاملTechnical Report: An Optimal Energy-Delay Tradeoff for Opportunistic Spectrum Access in Cognitive Radio Networks
Cognitive radio (CR) technology has been considered promising to enhance spectrum efficiency via opportunistic transmission at link level. Several existing works focus on either spectrum sensing or dynamic spectrum sharing. But CR protocols allow in general a secondary user to transmit only when a licensed channel is not occupied by primary user. However waiting for idle timeslot may include la...
متن کاملDynamic Spectrum Access in Cognitive Radio Networks
Spectrum inefficient utilization and growing in demand of wireless services is one of the challenges facing the wireless communication systems as the spectrum is a finite resource. There is a need of better and smarter exploitation of the limited spectrum which will enables the usage and to allowing sharing of temporally unused spectrum allocated to the television broadcast service in non inter...
متن کاملEntropy-Based Opportunistic Spectrum Access Algorithm in Cognitive Radio Networks
In this paper, we propose an opportunistic channel access scheme based on weighted residual entropy function in cognitive radio networks. This central decision scheme significantly improves spectrum utilization compared with random and first opportunistic spectrum access schemes. Particularly, in this mechanism, appropriate spectrum opportunity will be selected based on the usefulness of idle c...
متن کاملPlanning Approach to Dynamic Spectrum Access in Cognitive Radio Networks
Over the past few years, significant effort has been put into various treatments of dynamic spectrum access. This study has resulted in a many protocols and heuristic techniques for coexistence between primary and secondary users in a frequency band. However, none of these approaches has resulted in a description suitable for implementation on a generalpurpose cognitive engine. As a result, dev...
