Efficient spectrum availability information recovery for wideband dsa networks: A weighted compressive sampling approach
Khalfi B.; Hamdaoui B.; Guizani M.; Zorba N. ( Institute of Electrical and Electronics Engineers Inc. , 2018 , Article)There have recently been research efforts that leverage compressive sampling to enable wideband spectrum sensing recovery at sub-Nyquist rates. These efforts consider homogenous wideband spectrum, where all bands are assumed ... -
Implementation and Analysis of Reward Functions under Different Traffic Models for Distributed DSA Systems
Hamdi, R.; Ben Ghorbel, M.; Hamdaoui, B.; Guizani, Mohsen; Khalfi, B. ( IEEE , 2015 , Article)In this paper, we implement and analyze a resource allocation protocol for distributed dynamic spectrum allocation (DSA) systems. The DSA protocol is a learning-based protocol that allows secondary users (SU) to exploit ... -
Large-scale cognitive cellular systems: Resource management overview
Guizani M.; Khalfi B.; Ghorbel M.B.; Hamdaoui B. ( Institute of Electrical and Electronics Engineers Inc. , 2015 , Article Review)This article presents recent advancements in resource management for large-scale DSA systems. Although the problem of spectrum and power allocation is well addressed in the literature, the need for more efficient algorithms ...
