چکیده

We study joint rate control and resource allocation with a packet collision constraint that maximizes the total utility of secondary users in cognitive radio networks. We formulate and decouple the original optimization problem into separable subproblems and then develop an algorithm that converges to optimal rate control and resource allocation. The proposed algorithm can operate on different time-scales to reduce the amortized time complexity. key words: utility maximization, rate control and resource allocation, cognitive radio networks

Secondary User Sensing Time Optimization in Sensing-Transmission Scheduling for Dynamic Spectrum Access in Cognitive Radio

Corresponding Author: Inderdeep Kaur Aulakh University Institute of Engineering and Technology, Panjab University, Chandigarh, India Email: [email protected] Abstract: The constraint of limited frequency spectrum for wireless communication is very daunting. The radio spectrum licensed to permanent users is wasted at times when not used continuously. Cognitive radio technology involves a ch...

Cognitive Radio Access Optimization Under Primary Queue Stability Constraint

We propose a network access optimization for cognitive radio nodes aimed at throughput maximization under the constraint of primary node queue stability. To maintain primary queue stability, our approach moves beyond the traditional listen-before-talk opportunistic access by allowing cognitive radios to over-hear and utilize ACK/NAK feedback signals on packet reception from the primary receiver...

Optimization of Transmission Strategies for Opportunistic Access in Cognitive Radio Networks

Cognitive radio is a promising technology to mitigate spectrum shortage in wireless communications. It enables secondary users (SUs) to opportunistically access low-occupancy primary spectral bands as long as the primary user (PU) access is protected. Such a protection requirement is particularly challenging for multiple SUs over a potentially wide geographical area. In this paper, we study the...
