We consider the minimization of packet transmission duration on an energy harvesting broadcast channel ( BC). Energy and data arrivals are assumed to occur at arbitrary but known instants. An achievable rate region with structural properties satisfied by the two-user AWGN BC capacity region is assumed. Structural properties of power and rate allocation in an optimal policy are established, as well as the uniqueness of the optimal policy under the condition that all the data of the "weaker" user are available at the beginning. An iterative algorithm, DuOpt, based on block coordinate descent that achieves the same structural properties as the optimal is described.

Optimal Packet Scheduling on an Energy Harvesting Broadcast Link
Antepli, Mehmet Akif; Uysal, Elif; Erkal, Hakan (2011-09-01)
The minimization of transmission completion time for a given number of bits per user in an energy harvesting communication system, where energy harvesting instants are known in an offline manner is considered. An achievable rate region with structural properties satisfied by the 2-user AWGN Broadcast Channel capacity region is assumed. It is shown that even though all data are available at the beginning, a non-negative amount of energy from each energy harvest is deferred for later use such that the transmi...
Optimal offline broadcast scheduling with an energy harvesting transmitter
Erkal, Hakan; Ozcelik, F. Mehmet; Uysal, Elif (Springer Science and Business Media LLC, 2013-07-18)
We consider an energy harvesting transmitter broadcasting individual data to two receivers. Data packets intended for each user are assumed to arrive at arbitrary but known instants. The goal is to minimize the total transmission time of the packets arriving within a certain time window, using the energy harvested during this time. Energy harvests are also modelled to occur at known discrete instants. An achievable rate region with structural properties satisfied by the two-user additive white Gaussian nois...
Microwave Energy Harvesting by using a Broadband Fractal Antenna and a Dual-Band Rectifier
Ozdemir, Huriye; Nesimoglu, Tayfun (2018-11-02)
In this paper, a broadband rectenna for radio frequency (RF) energy harvesting is presented. The proposed rectenna consists of a broadband fractal slot antenna and a voltage doubler rectifier circuit with a novel matching network. First of all, a broadband fractal antenna is proposed, which covers the most frequently encountered frequency bands which are located around 1800 MHz, 2.1 GHz, 2.4 GHz, and 2.45 GHz corresponding to the standards like GSM, UMTS, ISM, and WLAN, respectively. The return loss of the ...
OPTIMAL CONTROLLER DESIGN FOR SPEED GOVERNORS OF HYDROELECTRIC POWER PLANT
Altinoz, Okkes Tolga; KOŞALAY, İLHAN; Gezer, Derya (VSB - Technical University of Ostrava, 2020-06-01)
Speed governors have critical importance on hydroelectric power plants, which are adjusted to the rotating speed of hydroelectric generation based on load demand of the grid. The rotating speed is the main factor to balance power generation and load demand. The well-designed controller is needed to control speed governors with high accuracy. A well-defined model is needed to obtain desired control structure. Therefore, in this study, initially, the mathematical model of a hydroelectric power plant is obtain...
Adaptive modulation for completion time minimization in wireless broadcast networks
Yüksel Turgut, Ayşe Melda; Genc, Yasin (2017-01-01)
In this work we study the effect of hierarchical modulation on completion time minimization in wireless broadcast channels. Time needed to transmit all bits intended for a particular user is defined as its completion time. In this work we investigate minimizing the maximum completion time over all users in a broadcast channel using hierarchical modulation. We compare time division, opportunistic scheduling, and three different adaptive modulation schemes: rate adaptive hierarchical modulation assisted trans...
