Device-to-Device Communication Underlaying a Finite Cellular Network Region
Jing Guo, Salman Durrani, Xiangyun Zhou +1
Underlay in-band device-to-device (D2D) communication can improve the spectrum efficiency of cellular networks. However, the coexistence of D2D and cellular users causes inter-cell…
Secure Routing in Multihop Wireless Ad-hoc Networks with Decode-and-Forward Relaying
Jianping Yao, Suili Feng, Xiangyun Zhou +1
In this paper, we study the problem of secure routing in a multihop wireless ad-hoc network in the presence of randomly distributed eavesdroppers. Specifically, the locations of th…
Energy Harvesting Wireless Sensor Networks: Delay Analysis Considering Energy Costs of Sensing and Transmission
Wanchun Liu, Xiangyun Zhou, Salman Durrani +2
Energy harvesting (EH) provides a means of greatly enhancing the lifetime of wireless sensor nodes. However, the randomness inherent in the EH process may cause significant delay f…
Mode Selection, Resource Allocation and Power Control for D2D-Enabled Two-Tier Cellular Network
Yifei Huang, Ali A. Nasir, Salman Durrani +1
This paper proposes a centralized decision making framework at the macro base station (MBS) for device to device (D2D) communication underlaying a two-tier cellular network. We con…
Event-Trigger Based Robust-Optimal Control for Energy Harvesting Transmitter
Yirui Cong, Xiangyun Zhou
This paper studies an online algorithm for an energy harvesting transmitter, where the transmission (completion) time is considered as the system performance. Unlike the existing o…
Achieving secrecy without knowing the number of eavesdropper antennas
Biao He, Xiangyun Zhou, Thushara D. Abhayapala
The existing research on physical layer security commonly assumes the number of eavesdropper antennas to be known. Although this assumption allows one to easily compute the achieva…
Interference Prediction in Mobile Ad Hoc Networks with a General Mobility Model
Yirui Cong, Xiangyun Zhou, Rodney A. Kennedy
In a mobile ad hoc network (MANET), effective prediction of time-varying interferences can enable adaptive transmission designs and therefore improve the communication performance.…
Artificial-Noise-Aided Secure Multi-Antenna Transmission with Limited Feedback
Xi Zhang, Matthew R. McKay, Xiangyun Zhou +1
We present an optimized secure multi-antenna transmission approach based on artificial-noise-aided beamforming, with limited feedback from a desired single-antenna receiver. To dea…
