An equivalent nonlinear optimization model with triangular low-rank factorization for semidefinite programs
Yuya Yamakawa, Tetsuya Ikegami, Ellen H. Fukuda +1
In this paper, we propose a new nonlinear optimization model to solve semidefinite optimization problems (SDPs), providing some properties related to local optimal solutions. The p…
Energy Efficient Resource Allocation Optimization in Fog Radio Access Networks with Outdated Channel Knowledge
Thi Ha Ly Dinh, Megumi Kaneko, Ellen Hidemi Fukuda +1
Fog Radio Access Networks (F-RAN) are gaining worldwide interests for enabling mobile edge computing for Beyond 5G. However, to realize the future real-time and delay-sensitive app…
Joint Allocation Strategies of Power and Spreading Factors with Imperfect Orthogonality in LoRa Networks
Licia Amichi, Megumi Kaneko, Ellen Hidemi Fukuda +2
The LoRa physical layer is one of the most promising Low Power Wide-Area Network (LPWAN) technologies for future Internet of Things (IoT) applications. It provides a flexible adapt…
A barrier-type method for multiobjective optimization
Ellen H. Fukuda, L. M. Grana Drummond, Fernanda M. P. Raupp
For solving constrained multicriteria problems, we introduce the multiobjective barrier method (MBM), which extends the scalar-valued internal penalty method. This multiobjective v…
