A Beaconless Asymmetric Energy-Efficient Time Synchronization Scheme for Resource-Constrained Multi-Hop Wireless Sensor Networks
Xintao Huan, Kyeong Soo Kim, Sanghyuk Lee +2
The ever-increasing number of WSN deployments based on a large number of battery-powered, low-cost sensor nodes, which are limited in their computing and power resources, puts the…
Hierarchical Auxiliary Learning
Jaehoon Cha, Kyeong Soo Kim, Sanghyuk Lee
Conventional application of convolutional neural networks (CNNs) for image classification and recognition is based on the assumption that all target classes are equal(i.e., no hier…
On the Transformation of Latent Space in Autoencoders
Jaehoon Cha, Kyeong Soo Kim, Sanghyuk Lee
Noting the importance of the latent variables in inference and learning, we propose a novel framework for autoencoders based on the homeomorphic transformation of latent variables,…
XJTLUIndoorLoc: A New Fingerprinting Database for Indoor Localization and Trajectory Estimation Based on Wi-Fi RSS and Geomagnetic Field
Zhenghang Zhong, Zhe Tang, Xiangxing Li +10
In this paper, we present a new location fingerprinting database comprised of Wi-Fi received signal strength (RSS) and geomagnetic field intensity measured with multiple devices at…
Simulation Study of an Energy-Efficient Time Synchronization Scheme based on Source Clock Frequency Recovery in Asymmetric Wireless Sensor Networks
Kyeong Soo Kim, Sanghyuk Lee, Eng Gee Lim
In this paper we report preliminary results of a simulation study on an energy-efficient time synchronization scheme based on source clock frequency recovery (SCFR) at sensor nodes…
