Compressive Subspace Learning with Antenna Cross-correlations for Wideband Spectrum Sensing
Tierui Gong, Zhijia Yang, Meng Zheng +2
Compressive subspace learning (CSL) with the exploitation of space diversity has found a potential performance improvement for wideband spectrum sensing (WBSS). However, previous w…
End-to-end Throughput Maximization for Underlay Multi-hop Cognitive Radio Networks with RF Energy Harvesting
Chi Xu, Meng Zheng, Wei Liang +2
This paper studies a green paradigm for the underlay coexistence of primary users (PUs) and secondary users (SUs) in energy harvesting cognitive radio networks (EH-CRNs), wherein b…
A Connectivity-Aware Approximation Algorithm for Relay Node Placement in Wireless Sensor Networks
Chaofan Ma, Wei Liang, Meng Zheng
In two-tiered Wireless Sensor Networks (WSNs) relay node placement is one of the key factors impacting the network energy consumption and the system overhead. In this paper, a nove…
Set Covering-based Approximation Algorithm for Delay Constrained Relay Node Placement in Wireless Sensor Networks
Chaofan Ma, Wei Liang, Meng Zheng
The Delay Constrained Relay Node Placement (DCRNP) problem in Wireless Sensor Networks (WSNs) aims to deploy minimum relay nodes such that for each sensor node there is a path conn…
Planning of Cellular Networks Enhanced by Energy Harvesting
Meng Zheng, Przemysław Pawełczak, Sławomir Stańczak +1
We pose a novel cellular network planning problem, considering the use of renewable energy sources and a fundamentally new concept of energy balancing, and propose a novel algorith…
