Price-Based Distributed Offloading for Mobile-Edge Computing with Computation Capacity Constraints
Mengyu Liu, Yuan Liu
Mobile-edge computing (MEC) is a promising technology to enable real-time information transmission and computing by offloading computation tasks from wireless devices to network ed…
Secrecy Rate Maximization with Outage Constraint in Multihop Relaying Networks
Jianping Yao, Yuan Liu
In this paper, we study the secure transmission in multihop wireless networks with randomize-and-forward (RaF) relaying, in the presence of randomly distributed eavesdroppers. By c…
Physical Layer Security in Heterogeneous Networks with Jammer Selection and Full-Duplex Users
Weijun Tang, Suili Feng, Yuehua Ding +1
In this paper, we enhance physical layer security for downlink heterogeneous networks (HetNets) by using friendly jammers and full-duplex users. The jammers are selected to transmi…
Exploiting Interference for Secrecy Wireless Information and Power Transfer
Yuan Liu, Jie Xu, Rui Zhang
Radio-frequency (RF) signals enabled wireless information and power transfer (WIPT) is a cost-effective technique to achieve two-way communications and at the same time provide ene…
Joint resource allocation in SWIPT-based multi-antenna decode-and-forward relay networks
Yuan Liu
In this paper, we consider relay-assisted simultaneous wireless information and power transfer (SWIPT) for two-hop cooperative transmission, where a half-duplex multi-antenna relay…
Power Allocation for Secure SWIPT Systems with Wireless-Powered Cooperative Jamming
Mengyu Liu, Yuan Liu
This paper considers wireless-powered cooperative jamming (CJ) to secure communication between a transmitter (Tx) and an information receiver (IR), in the presence of an energy rec…
