Dynamic Spectrum Access Strategy for Multi-Channel Cognitive Radio Networks
In this paper, we present a dynamic spectrum access strategy to reduce the average overall system time of secondary users (SUs) in multi-channel cognitive radio networks. Before transmitting a packet, SU senses the spectrum environment. If there are free channels in the system, SU randomly selects one for transmitting. If all the channels are busy, we consider a probability-based spectrum selec...
متن کاملOptimal spectrum access and power control of secondary users in cognitive radio networks
In future 5G communication system, radio resources can be effectively reused by cognitive radio networks (CRNs), where a lot of secondary users (SUs) are able to access the spectrum of primary users (PUs). In this paper, we analyze the optimal spectrum access and power control of SUs on multiple bands with the target of maximizing the average sum rate (ASR) of SUs. Specifically, based on the st...
متن کاملDistributed Optimal Channel Access in Cognitive Radio Networks
Cognitive radio networks (CRNs) let unlicensed or secondary users (SUs) access licensed spectra, improving wireless resource utilization and addressing the problem of spectrum shortage. SUs are allowed spectrum access only when they don’t cause unacceptable levels of interference to licensed or primary users (PUs). Although throughput-optimal algorithms based on the well-known maximal-weight sc...
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 کاملOptimal Channel Exploration for Cognitive Radio Networks
In this paper, the optimal channel exploration is proposed for cognitive radio networks. In the networks, primary users (PUs) utilize the channels with fixed slot structure. Cognitive users (CUs) should sense the channels within each slot. We study the relationship of the channel states between the nearby slots and range channels by the decreasing idle probabilities of all channels. Then we use...
