Channel swapping based dynamic channel allocation [PDF]
ICUPC '98. IEEE 1998 International Conference on Universal Personal Communications. Conference Proceedings (Cat. No.98TH8384), 2002 Several DCA schemes have been proposed to improve the quality and carried traffic in mobile cellular radio system. Most of these schemes assign channels to calls based on the constraint imposed by cochannel interference, and ignore the ACI (adjacent channel interference) constraint.

A Robust Power Allocation Algorithm for Cognitive Radio Networks Based on Hybrid PSO
Sensors, 2022 The use of a cognitive radio power allocation algorithm is an effective method to improve spectral utilization. However, there are three problems with traditional cognitive radio power allocation algorithms: (1) based on the ideal channel model analysis,

An improved fast transform algorithm based on adaptive hybrid channel allocation in TSCH networks
EURASIP Journal on Wireless Communications and Networking, 2020 Time Slotted Channel Hopping (TSCH) is one of the five access behavior technologies defined in the IEEE 802.15.4e standard. Research shows that the wireless sensor network with single dynamic and static channel allocation in TSCH mode has higher ...
