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…
A flexible algorithm to offload DAG applications for edge computing
Gabriel F. C. de Queiroz, José F. de Rezende, Valmir C. Barbosa
Multi-access Edge Computing (MEC) is an enabling technology to leverage new network applications, such as virtual/augmented reality, by providing faster task processing at the netw…
Shape complexity in cluster analysis
Eduardo J. Aguilar, Valmir C. Barbosa
In cluster analysis, a common first step is to scale the data aiming to better partition them into clusters. Even though many different techniques have throughout many years been i…
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…
Interspecies evolutionary dynamics mediated by public goods in bacterial quorum sensing
Eduardo J. Aguilar, Valmir C. Barbosa, Raul Donangelo +1
Bacterial quorum sensing is the communication that takes place between bacteria as they secrete certain molecules into the intercellular medium that later get absorbed by the secre…
Scheduling wireless links in the physical interference model by fractional edge coloring
Guilherme I. Ricardo, José F. de Rezende, Valmir C. Barbosa
We consider the problem of scheduling the links of wireless mesh networks for capacity maximization in the physical interference model. We represent such a network by an undirected…
