Exact solution of the full RMSA problem in elastic optical networks
Fabio David, José F. de Rezende, Valmir C. Barbosa
Exact solutions of the Routing, Modulation, and Spectrum Allocation (RMSA) problem in Elastic Optical Networks (EONs), so that the number of admitted demands is maximized while tho…
Near-optimal pilot assignment in cell-free massive MIMO
Raphael M. Guedes, José F. de Rezende, Valmir C. Barbosa
Cell-free massive MIMO systems are currently being considered as potential enablers of future (6G) technologies for wireless communications. By combining distributed processing and…
Enhancing Network Slicing Architectures with Machine Learning, Security, Sustainability and Experimental Networks Integration
Joberto S. B. Martins, Tereza C. Carvalho, Rodrigo Moreira +19
Network Slicing (NS) is an essential technique extensively used in 5G networks computing strategies, mobile edge computing, mobile cloud computing, and verticals like the Internet…

Optimal Resource Allocation with Delay Guarantees for Network Slicing in Disaggregated RAN
Flávio G. C. Rocha, Gabriel M. F. de Almeida, Kleber V. Cardoso +2
In this article, we propose a novel formulation for the resource allocation problem of a sliced and disaggregated Radio Access Network (RAN) and its transport network. Our proposal…
Integrated optimization of heterogeneous-network management and the elusive role of macrocells
Raphael M. Guedes, José F. de Rezende, Valmir C. Barbosa
We consider heterogeneous wireless networks in the physical interference model and introduce a new formulation of the mixed-integer nonlinear programming problem that addresses bas…
Scheduling wireless links in the physical interference model by fractional edge coloring
Guilherme I. Ricardo, José F. de Rezende, Valmir C. Barbosa

Local heuristic for the refinement of multi-path routing in wireless mesh networks
Fabio R. J. Vieira, José F. de Rezende, Valmir C. Barbosa +1
We consider wireless mesh networks and the problem of routing end-to-end traffic over multiple paths for the same origin-destination pair with minimal interference. We introduce a…
Scheduling links for heavy traffic on interfering routes in wireless mesh networks
Fabio R. J. Vieira, José F. de Rezende, Valmir C. Barbosa +1
We consider wireless mesh networks and the problem of scheduling the links of a given set of routes under the assumption of a heavy-traffic pattern. We assume some TDMA protocol pr…
