From Real to Complex: Enhancing Radio-based Activity Recognition Using Complex-Valued CSI
Bo Wei, Wen Hu, Mingrui Yang +1
Activity recognition is an important component of many pervasive computing applications. Radio-based activity recognition has the advantage that it does not have the privacy concer…
Compressive hyperspectral imaging via adaptive sampling and dictionary learning
Mingrui Yang, Frank de Hoog, Yuqi Fan +1
In this paper, we propose a new sampling strategy for hyperspectral signals that is based on dictionary learning and singular value decomposition (SVD). Specifically, we first lear…
Autonomous surveillance for biosecurity
Raja Jurdak, Alberto Elfes, Branislav Kusy +5
The global movement of people and goods has increased the risk of biosecurity threats and their potential to incur large economic, social, and environmental costs. Conventional man…
SimpleTrack:Adaptive Trajectory Compression with Deterministic Projection Matrix for Mobile Sensor Networks
Rajib Rana, Mingrui Yang, Tim Wark +2
Some mobile sensor network applications require the sensor nodes to transfer their trajectories to a data sink. This paper proposes an adaptive trajectory (lossy) compression algor…
dRTI: Directional Radio Tomographic Imaging
Bo Wei, Ambuj Varshney, Wen Hu +3
Radio tomographic imaging (RTI) enables device free localisation of people and objects in many challenging environments and situations. Its basic principle is to detect the changes…
Ear-Phone: A Context-Aware Noise Mapping using Smart Phones
Rajib Rana, Chun Tung Chou, Nirupama Bulusu +2
A noise map facilitates the monitoring of environmental noise pollution in urban areas. However, state-of-the-art techniques for rendering noise maps in urban areas are expensive a…
Signal Reconstruction from Rechargeable Wireless Sensor Networks using Sparse Random Projections
Rajib Rana, Wen Hu, Chun Tung Chou
Due to non-homogeneous spread of sunlight, sensing nodes possess non-uniform energy budget in recharge- able Wireless Sensor Networks (WSNs). An energy-aware workload distribution…
