Optimized Sparse Network Coverage via L1-norm Minimization
Souvik Paul, Iván Alexander Morales Sandoval, Giuseppe Thadeu Freitas de Abreu
The selection of nodes that can serve as cluster heads, local sinks and gateways is a critical challenge in distributed sensor and communication networks. This paper presents a nov…
Flexible Intelligent Metasurfaces in High-Mobility MIMO Integrated Sensing and Communications
Kuranage Roche Rayan Ranasinghe, Jiancheng An, Iván Alexander Morales Sandoval +4
We propose a novel doubly-dispersive (DD) multiple-input multiple-output (MIMO) channel model incorporating flexible intelligent metasurfaces (FIMs), which is suitable for integrat…
Metasurfaces-Integrated Doubly-Dispersive MIMO: Channel Modeling and Optimization
Kuranage Roche Rayan Ranasinghe, Hyeon Seok Rou, Iván Alexander Morales Sandoval +2
The doubly-dispersive (DD) channel structure has played a pivotal role in wireless communications, particularly in high-mobility scenarios and integrated sensing and communications…
Parametrized Stacked Intelligent Metasurfaces for Bistatic Integrated Sensing and Communications
Kuranage Roche Rayan Ranasinghe, Iván Alexander Morales Sandoval, Giuseppe Thadeu Freitas de Abreu +1
We consider stacked intelligent metasurfaces (SIMs) as a tool to improve the performance of bistatic integrated sensing and communications (ISAC) schemes. To that end, we optimize…
Post-Quantum Wireless-based Key Encapsulation Mechanism via CRYSTALS-Kyber for Resource-Constrained Devices
M. A. González de la Torre, I. A. Morales Sandoval, Giuseppe Thadeu Freitas de Abreu +1
We consider the problem of adapting a Post-Quantum cryptosystem to be used in resource-constrained devices, such as those typically used in Device-to-Device and Internet of Things…
A Robust Routing Protocol for 5G Mesh Networks
Niclas Führling, Ivan Alexander Morales Sandoval, Giuseppe Thadeu Freitas de Abreu
We consider a novel routing protocol suitable for ad-hoc networks with dynamically changing topologies, such as DECT 2020 NR (NR+) systems, which often lead to missing links betwee…
