Optimizing Power Allocation in LoRaWAN IoT Applications [PDF]

open access: yesIEEE Internet of Things Journal, 2022
Long Range Wide Area Network (LoRaWAN) is one of the most promising IoT technologies that are widely adopted in low-power wide-area networks (LPWAN). LoRaWAN faces scalability issues due to a large number of nodes connected to the same gateway and sharing the same channel.

Spectrum-Energy Efficiency Tradeoff in Decode-and-Forward Two-Way Multi-Relay Networks

open access: yesIEEE Access, 2021
Owing to its high spectrum efficiency (SE), two-way relaying has aroused tremendous research interests. In this paper, the spectrum-energy efficiency (SE-EE) trade-off in decode-and-forward (DF) two-way multi-relay networks is studied by considering non ...

Optimal downlink power allocation in cellular networks [PDF]

open access: yesPhysical Communication, 2015
In this paper, we introduce a novel approach for power allocation in cellular networks. In our model, we use sigmoidal-like utility functions to represent different users' modulation schemes. Each utility function is a representation of the probability of successfully transmitted packets per unit of power consumed by a user, when using a certain ...

Optimal Power Allocation in Multiuser OFDM Systems [PDF]

open access: yesGLOBECOM '03. IEEE Global Telecommunications Conference (IEEE Cat. No.03CH37489), 2004
Multiuser orthogonal frequency division multiplexing (MU-OFDM) is a promising technique for achieving high downlink capacities in future cellular systems. A key issue in MU-OFDM is the allocation of the OFDM subcarriers and power among users sharing the channel. Previous allocation algorithms cannot ensure fairness in advance.

Optimal Power Allocation for Secure Estimation of Multiple Parameters [PDF]

open access: yesIEEE Signal Processing Letters, 2021
Optimal power allocation for secure estimation of multiple deterministic parameters is investigated under a total power constraint. The goal is to minimize the Cramer-Rao lower bound (CRLB) at an intended receiver while keeping estimation errors at an eavesdropper above specified target levels.

A note on power allocation for optimal capacity

open access: yesCoRR, 2022
The problems of determining the optimal power allocation, within maximum power bounds, to (i) maximize the minimum Shannon capacity, and (ii) minimize the weighted latency are considered. In the first case, the global optima can be achieved in polynomial time by solving a sequence of linear programs (LP).
