Robust time-of-arrival localization via ADMM
Wenxin Xiong, Christian Schindelhauer, Hing Cheung So
This article considers the problem of source localization (SL) using possibly unreliable time-of-arrival (TOA) based range measurements. Adopting the strategy of statistical robust…
Simulation of a first prototypical 3D solution for Indoor Localization based on Directed and Reflected Signals
Sneha Mohanty, Milan Müller, Christian Schindelhauer
We introduce a solution for a specific case of Indoor Localization which involves a directed signal, a reflected signal from the wall and the time difference between them. This sol…
Globally Optimized TDOA High Frequency Source Localization Based on Quasi-Parabolic Ionosphere Modeling and Collaborative Gradient Projection
Wenxin Xiong, Christian Schindelhauer, Hing Cheung So
We investigate the problem of high frequency (HF) source localization using the time-difference-of-arrival (TDOA) observations of ionosphere-refracted radio rays based on quasi-par…
QUDOS: Quorum-Based Cloud-Edge Distributed DNNs for Security Enhanced Industry 4.0
Kevin Wallis, Christoph Reich, Blesson Varghese +1
Distributed machine learning algorithms that employ Deep Neural Networks (DNNs) are widely used in Industry 4.0 applications, such as smart manufacturing. The layers of a DNN can b…
Two Efficient and Easy-to-Use NLOS Mitigation Solutions to Indoor 3-D AOA-Based Localization
Wenxin Xiong, Joan Bordoy, Andrea Gabbrielli +6
This paper proposes two efficient and easy-to-use error mitigation solutions to the problem of three-dimensional (3-D) angle-of-arrival (AOA) source localization in the mixed line-…
Concealed Communication in Online Social Networks
Fabian Schillinger, Christian Schindelhauer
Online social networks are used frequently by many people: Staying in contact with friends and sharing experiences with them is very important. However, users are increasingly conc…
A Proxy-Based Encrypted Online Social Network With Fine-Grained Access
Fabian Schillinger, Christian Schindelhauer
When using Online Social Networks, users often share information with different social groups. When considering the backgrounds of the groups there is often no or little intersecti…
Partitioned Private User Storages in End-to-End Encrypted Online Social Networks
Fabian Schillinger, Christian Schindelhauer
In secure Online Social Networks (OSN), often end-to-end encryption approaches are used. This ensures the privacy of communication between the participants. To manage, store, or tr…
Neurodynamic TDOA localization with NLOS mitigation via maximum correntropy criterion
Wenxin Xiong, Christian Schindelhauer, Hing Cheung So +2
In this paper, we exploit the maximum correntropy criterion (MCC) to robustify the traditional time-difference-of-arrival (TDOA) location estimator in the presence of non-line-of-s…
Maximum correntropy criterion for robust TOA-based localization in NLOS environments
Wenxin Xiong, Christian Schindelhauer, Hing Cheung So +1
We investigate the problem of time-of-arrival (TOA) based localization under possible non-line-of-sight (NLOS) propagation conditions. To robustify the squared-range-based location…
TDOA-based localization with NLOS mitigation via robust model transformation and neurodynamic optimization
Wenxin Xiong, Christian Schindelhauer, Hing Cheung So +3
This paper revisits the problem of locating a signal-emitting source from time-difference-of-arrival (TDOA) measurements under non-line-of-sight (NLOS) propagation. Many currently…
Crucial and Redundant Shares and Compartments in Secret Sharing
Fabian Schillinger, Christian Schindelhauer
Secret sharing is the well-known problem of splitting a secret into multiple shares, which are distributed to shareholders. When enough or the correct combination of shareholders w…
Collaborative Broadcast in O(log log n) Rounds
Christian Schindelhauer, Aditya Oak, Thomas Janson
We consider the multihop broadcasting problem for nodes placed uniformly at random in a disk and investigate the number of hops required to transmit a signal from the central n…
T-ROME: A Simple and Energy Efficient Tree Routing Protocol for Low-Power Wake-up Receivers
Timo Kumberg, Marc Schink, Leonhard Reindl +1
Wireless sensor networks are deployed in many monitoring applications but still suffer from short lifetimes originating from limited energy sources and storages. Due to their low-p…
Cyclone Codes
Christian Schindelhauer, Andreas Jakoby, Sven Köhler
We introduce Cyclone codes which are rateless erasure resilient codes. They combine Pair codes with Luby Transform (LT) codes by computing a code symbol from a random set of data s…
Receiving Pseudorandom PSK
Thomas Janson, Christian Schindelhauer
Pseudorandom PSK [1] enables parallel communication on the same carrier frequency and at the same time. We propose different signal processing methods to receive data modulated wit…
Ad-Hoc Network Unicast in Time O(log log n) using Beamforming
Thomas Janson, Christian Schindelhauer
We investigate the unicast problem for ad-hoc networks in the plane using MIMO techniques. In particular, we use the multi-node beamforming gain and present a self-synchronizing al…
