Analyzing cognitive network access efficiency under limited spectrum handoff agility
NoroozOliaee, MohammadJavad; Hamdaoui, Bechir; Cheng, Xiuzhen; Znati, Taieb; Guizani, Mohsen ( Institute of Electrical and Electronics Engineers Inc. , 2014 , Article)Most existing studies on cognitive-radio networks assume that cognitive users (CUs) can switch to any available channel, regardless of the frequency gap between a target channel and the current channel. However, due to ... -
Distributed dynamic spectrum access with adaptive power allocation: Energy efficiency and cross-layer awareness
Ben Ghorbel, Mahdi; Hamdaoui, Bechir; Hamdi, Rami; Guizani, Mohsen; NoroozOliaee, MohammadJavad ( Institute of Electrical and Electronics Engineers Inc. , 2014 , Conference Paper)This paper proposes energy and cross-layer aware resource allocation techniques that allow dynamic spectrum access users, by means of learning algorithms, to locate and exploit unused spectrum opportunities effectively. ... -
Forced spectrum access termination probability analysis under restricted channel handoff
NoroozOliaee, MohammadJavad; Hamdaoui, Bechir; Znati, Taieb; Guizani, Mohsen (2012 , Conference Paper)Most existing works on cognitive radio networks assume that cognitive (or secondary) users are capable of switching/jumping to any available channel, regardless of the frequency gap between the target and the current ... -
Maximizing secondary-user satisfaction in large-scale DSA systems through distributed team cooperation
NoroozOliaee, MohammadJavad; Hamdaoui, Bechir; Guizani, Mohsen (2012 , Article)We develop resource and service management techniques to support secondary users (\su s) with QoS requirements in large-scale distributed dynamic spectrum access (\osa) systems. The proposed techniques empower \su s to ... -
Online multi-resource scheduling for minimum task completion time in cloud servers
NoroozOliaee, MohammadJavad; Hamdaoui, Bechir; Guizani, Mohsen; Ben Ghorbel, Mahdi ( Institute of Electrical and Electronics Engineers Inc. , 2014 , Conference Paper)We design a simple and efficient online scheme for scheduling cloud tasks requesting multiple resources, such as CPU and memory. The proposed scheme reduces the queuing delay of the cloud tasks by accounting for their ...
