Fast Distributed Subspace Projection via Graph Filters
Weerasinghe, Thilina Nuwan; Romero, Daniel; Asensio-Marco, César; Beferull-Lozano, Baltasar (Chapter; Peer reviewed, 2018)A significant number of linear inference problems in wireless sensor networks can be solved by projecting the observed signal onto a given subspace. Decentralized approaches avoid the need for performing such an operation ... -
Preamble Reservation Based Access for Grouped mMTC Devices with URLLC Requirements
Weerasinghe, Thilina Nuwan; Balapuwaduge, Indika A. M.; Li, Frank Yong (Journal article; Peer reviewed, 2019)Ultra-reliable low latency communication (URLLC) and massive machine type communications (mMTC) are two of the three major technological pillars in 5G. For medium access in mMTC scenarios, e.g., smart cities, a major ... -
Preamble Transmission Prediction for mMTC Bursty Traffic : A Machine Learning based Approach
Søraa, Aasmund; Weerasinghe, Thilina Nuwan; Balapuwaduge, Indika A. M.; Li, Frank Yong (Journal article; Peer reviewed, 2020) -
Priority Enabled Grant-Free Access With Dynamic Slot Allocation for Heterogeneous mMTC Traffic in 5G NR Networks
Weerasinghe, Thilina Nuwan; Giner, Vicente Casares; Balapuwaduge, Indika A.M.; Li, Frank Yong (Peer reviewed; Journal article, 2021)Although grant-based mechanisms have been a predominant approach for wireless access for years, the additional latency required for initial handshake message exchange and the extra control overhead for packet transmissions ... -
Priority-based initial access for URLLC traffic in massive IoT networks: Schemes and performance analysis
Weerasinghe, Thilina Nuwan; Balapuwaduge, Indika A.M.; Li, Frank Young (Peer reviewed; Journal article, 2020)At a density of one million devices per square kilometer, the10’s of billions of devices, objects, and machines that form a massive Internet of things (mIoT) require ubiquitous connectivity. Among a massive number of IoT ... -
Topology Design to Increase Network Lifetime in WSN for Graph Filtering in Consensus Processes
Ben Saad, Leila; Weerasinghe, Thilina Nuwan; Beferull-Lozano, Baltasar (European Signal Processing Conference (EUSIPCO);25 2017, Journal article; Peer reviewed, 2017)Graph filters, which are considered as the workhorses of graph signal analysis in the emerging field of signal processing on graphs, are useful for many applications such as distributed estimation in wireless sensor networks. ...
