Dynamic Base Station Operation in Large-Scale Green Cellular Networks
Yueling Che, Lingjie Duan, Rui Zhang
In this paper, to minimize the on-grid energy cost in a large-scale green cellular network, we jointly design the optimal base station (BS) on/off operation policy and the on-grid…
Proactive Eavesdropping via Cognitive Jamming in Fading Channels
Jie Xu, Lingjie Duan, Rui Zhang
To enhance the national security, there is a growing need for government agencies to legitimately monitor suspicious communication links for preventing intended crimes and terror a…
Proactive Eavesdropping via Jamming for Rate Maximization over Rayleigh Fading Channels
Jie Xu, Lingjie Duan, Rui Zhang
Instead of against eavesdropping, this letter proposes a new paradigm in wireless security by studying how a legitimate monitor (e.g., government agencies) efficiently eavesdrops a…
To Motivate Social Grouping in Wireless Networks
Yu-Pin Hsu, Lingjie Duan
We consider a group of neighboring smartphone users who are roughly at the same time interested in the same network content, called common interests. However, ever-increasing data…
Multi-antenna Wireless Powered Communication with Co-channel Energy and Information Transfer
Yueling Che, Jie Xu, Lingjie Duan +1
This letter studies a multi-antenna wireless powered communication (WPC) system with co-channel energy and information transfer, where a wireless device (WD), powered up by wireles…
Cooperative Local Caching under Heterogeneous File Preferences
Yinghao Guo, Lingjie Duan, Rui Zhang
Local caching is an effective scheme for leveraging the memory of the mobile terminal (MT) and short range communications to save the bandwidth usage and reduce the download delay…
Adaptively Directional Wireless Power Transfer for Large-scale Sensor Networks
Zhe Wang, Lingjie Duan, Rui Zhang
Wireless power transfer (WPT) prolongs the lifetime of wireless sensor network by providing sustainable power supply to the distributed sensor nodes (SNs) via electromagnetic waves…
Energy Group-Buying with Loading Sharing for Green Cellular Networks
Jie Xu, Lingjie Duan, Rui Zhang
In the emerging hybrid electricity market, mobile network operators (MNOs) of cellular networks can make day-ahead energy purchase commitments at low prices and real-time flexible…
