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…
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…
