Spectrum sharing in energy harvesting cognitive radio networks: A cross-layer perspective
Tian Zhang, Wei Chen
In the paper, we present a cross-layer perspective on data transmission in energy harvesting cognitive radio networks (CRNs). The delay optimal power allocation is studied while ta…
Delay-optimal Data Transmission in Renewable Energy Aided Cognitive Radio Networks
Tian Zhang, Wei Chen
Renewable energy powered cognitive radio (CR) network has gained much attention due to its combination of the CR's spectrum efficiency and the renewable energy's "green" nature. In…
Coalitional Game Theoretic Approach for Cooperative Transmission in Vehicular Networks
Tian Zhang, Wei Chen, Zhu Han +1
Cooperative transmission in vehicular networks is studied by using coalitional game and pricing in this paper. There are several vehicles and roadside units (RSUs) in the networks.…
Opportunistic DF-AF Selection Relaying with Optimal Relay Selection in Nakagami-m Fading Environments
Tian Zhang, Wei Chen, Zhigang Cao
An opportunistic DF-AF selection relaying scheme with maximal received signal-to-noise ratio (SNR) at the destination is investigated in this paper. The outage probability of the o…
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…
