متن کاملEconomics of Spectrum Allocation in Cognitive Radio Networks
ECONOMICS OF SPECTRUM ALLOCATION IN COGNITIVE RADIO NETWORKS Gaurav S. Kasbekar Supervisor: Saswati Sarkar Cognitive radio networks (CRNs) are emerging as a promising technology for the efficient use of radio spectrum. In these networks, there are two levels of networks on each channel, primary and secondary, and secondary users can use the channel whenever the primary is not using it. Spectrum...
متن کاملRouting and Dynamic Spectrum Allocation for Cognitive Radio Networks
Cognitive Radio Networks (CRNs) are mainly used for path selection due to the added advantage of dynamic spectrum utilization when the frequency band is not under utilization. Path selection in multi-hop cognitive radio networks is done using dynamic spectrum allocation. We show that the overall throughput and the packet drop ratio determined by the proposed route selection strategy are better ...
متن کاملSpectrum Allocation in Cognitive Radio Networks Using Evolutionary Algorithms
One of the key objectives of evolving communication technologies is to maximize the utilization of the available spectrum by increasing the number of simultaneous users while reducing interferences among users. In cognitive radio networks, this problem is referred to as the spectrum allocation problem, and is shown to be NP-Hard. This chapter studies the use of evolutionary algorithms to solve ...
متن کاملSpectrum Allocation Based on Game Theory in Cognitive Radio Networks
As a kind of intelligent communication technology, the characteristic of dynamic spectrum allocation of cognitive radio provides feasible scheme for sharing with the spectrum resources among the primary user and secondary users, which solves the current spectrum resource scarcity problem. In this paper, we comprehensively explored the cognitive radio spectrum allocation models based on game the...
