The Optimal Allocation of Power in Organizations [PDF]
SSRN Electronic Journal, 2000 Starting from the separation between formal and real authority, the paper considers a hierarchical relation where delegation of control can be used as an incentive mechanism. It shows that delegation is optimal when parties’ interests are neither too divergent nor too close.

Optimal power allocation for DL NOMA systems
2017 25th Signal Processing and Communications Applications Conference (SIU), 2017 Non-orthogonal multiple access (NOMA) is an important candidate for 5G radio access technology. In NOMA transmitter, different users' signals are superposed on the same radio resource with different power allocation factors. The receiver removes other users' signals from the received signal before decoding its own signal.

Secure Communications With Cooperative Jamming: Optimal Power Allocation and Secrecy Outage Analysis [PDF]
IEEE Transactions on Vehicular Technology, 2017 This paper studies the secrecy rate maximization problem of a secure wireless communication system in the presence of multiple eavesdroppers. The security of the communication link is enhanced through cooperative jamming with the help of multiple jammers.

Optimal Power Allocation for Minimizing Outage Probability of UAV Relay Communications [PDF]
International Conference on Wireless Communications and Signal Processing, 2019 Unmanned aerial vehicle (UAV) networks have grown rapidly in recent years and become attractive for various emergence communications scenarios. In this paper, we consider a UAV acting as a relay node to assist wireless transmissions from a base station ...

Optimal and sub‐optimal rate and power allocation for random networks
Transactions on Emerging Telecommunications Technologies, 2023 AbstractWe consider the power and rate allocation for a transmission in a wireless network where the transmitter knows the channel state of the desired receiver but only knows the statistics of the interferes. While this scenario is often encountered in practice, and extremely important in dense networks, its optimal solution was not yet known.

Power Allocation for Goodput Optimization in BICM-OFDM Systems [PDF]
2008 IEEE International Conference on Communications, 2008 This paper deals with the power allocation problem for coded multicarrier transmission. Specifically, we focus on a bit interleaved coded modulation (BICM) packet transmission implemented with orthogonal frequency division multiplexing (OFDM) and in the presence of automatic repeat request (ARQ) protocol.

Multiobjective Optimization Model for Wind Power Allocation
Mathematical Problems in Engineering, 2017 There is an increasing need for the injection to the grid of renewable energy; therefore, to evaluate the optimal location of new renewable generation is an important task. The primary purpose of this work is to develop a multiobjective optimization model that permits finding multiple trade‐off solutions for the location of new wind power resources. It

Optimal Power Allocation by Imperfect Hardware Analysis in Untrusted Relaying Networks [PDF]
IEEE Transactions on Wireless Communications, 2017 By taking a variety of realistic hardware imperfections into consideration, we propose an optimal power allocation (OPA) strategy to maximize the instantaneous secrecy rate of a cooperative wireless network comprised of a source, a destination, and an ...
