Analyzing cognitive network access efficiency under limited spectrum handoff agility
(
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 ...
Improving macrocell downlink throughput in rayleigh fading channel environment through femtocell user cooperation
(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 ...
Maximizing secondary-user satisfaction in large-scale DSA systems through distributed team cooperation
(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 ...
Software-defined networking security: Pros and cons
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
Software-defined networking (SDN) is a new networking paradigm that decouples the forwarding and control planes, traditionally coupled with one another, while adopting a logically centralized architecture aiming to increase ...
