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 ... -
Cloud of things for sensing as a service: sensing resource discovery and virtualization
Abdelwahab, Sherif; Hamdaoui, Bechir; Guizani, Mohsen; Znati, Taieb ( Institute of Electrical and Electronics Engineers Inc. , 2015 , Conference Paper)We propose Cloud of Things for Sensing as a Service: a global architecture that scales up cloud computing by exploiting the global sensing resources of the highly dynamic and growing Internet of Things (IoT) to enable ... -
EM-MAC: An energy-aware multi-channel MAC protocol for multi-hop wireless networks
Sivanantha, Akhil; Hamdaoui, Bechir; Guizani, Mohsen; Cheng, Xiuzhen; Znati, Taieb (2012 , Conference Paper)We propose an energy-aware MAC protocol, referred to as EM-MAC, for multi-hop wireless networks with multi-channel access capabilities. EM-MAC relies on iMAC's efficient channel selection mechanism to resolve the medium ... -
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 ... -
Improving macrocell downlink throughput in rayleigh fading channel environment through femtocell user cooperation
Zaid, Adem M.; Hamdaoui, Bechir; Cheng, Xiuzhen; Znati, Taieb; Guizani, Mohsen (2013 , Article)This paper studies cooperative techniques that rely on femtocell user diversity to improve the downlink communication quality of macrocell users. We analytically derive and evaluate the achievable performance of these ...
