A Cross-layer Perspective on Energy Harvesting Aided Green Communications over Fading Channels
Tian Zhang, Wei Chen, Zhu Han +1
We consider the power allocation of the physical layer and the buffer delay of the upper application layer in energy harvesting green networks. The total power required for reliabl…
Coalitional Games in Partition Form for Joint Spectrum Sensing and Access in Cognitive Radio Networks
Walid Saad, Zhu Han, Rong Zheng +3
Unlicensed secondary users (SUs) in cognitive radio networks are subject to an inherent tradeoff between spectrum sensing and spectrum access. Although each SU has an incentive to…
Network Formation Games Among Relay Stations in Next Generation Wireless Networks
Walid Saad, Zhu Han, Tamer Başar +2
The introduction of relay station (RS) nodes is a key feature in next generation wireless networks such as 3GPP's long term evolution advanced (LTE-Advanced), or the forthcoming IE…
A Cooperative Bayesian Nonparametric Framework for Primary User Activity Monitoring in Cognitive Radio Network
Walid Saad, Zhu Han, H. Vincent Poor +2
This paper introduces a novel approach that enables a number of cognitive radio devices that are observing the availability pattern of a number of primary users(PUs), to cooperate…
Game Theoretic Methods for the Smart Grid
Walid Saad, Zhu Han, H. Vincent Poor +1
The future smart grid is envisioned as a large-scale cyber-physical system encompassing advanced power, communications, control, and computing technologies. In order to accommodate…
