Enerji hasadı yapan kablosuz ağlarda kullanıcı işbirliği ve kaynak tahsisi
(Tübitak, 2016-11)
Yeni nesil haberleşme sistemlerinde, pillere ya da şehir elektriğine bağımlı olarak çalışan klasik haberleşme bileşenlerinin yerlerini, enerjilerini çevreden hasat eden, çevreye duyarlı ve uzun kullanım ömrüne sahip ...
Kablosuz iletişim ağlarında kullanıcı yardımlaşmasına dayalı protokollerin dizaynı, optimum kaynak tahsisi ve iletim stratejileri
(Tübitak, 2009-03-01)
Bu projede, çoklu erişim kanallarında kanala uyarlamalı özgün kullanıcı işbirliği stratejileri geliştirilmiştir. Literatürde yalnızca iki kullanıcı için ele alınan karşılıklı ve eşzamanlı işbirliği teknikleri, üç kullanıcılı ...
Age of Information in Practice
(Cambridge University Press, 2023)
While age of Information (AoI) has gained importance as a metric characterizing the freshness of information in information-update systems and time-critical applications, most previous studies on AoI have been theoretical. ...
Improving age of information in random access channels
(Institute of Electrical and Electronics Engineers Inc., 2020-07)
We study Age of Information (AoI) in a random access channel where a number of devices try to send status updates over a common medium. Assuming a time-slotted scenario where multiple transmissions result in collision, we ...
When to pull data for minimum age penalty
(IEEE, 2021-10-18)
A communication receiver that wants to pull data from a remote sensor by exploiting wireless energy transfer is considered. The receiver has a long-term average energy budget for this operation, and its goal is to keep the ...
Optimal primary-secondary user pairing and power allocation in cognitive cooperative multiple access channels
(IEEE, 2014)
We develop jointly optimal power control and primary-secondary user partnering strategies for a cognitive cooperative multiple access channel with K primary and K secondary users. For each primary user, a cooperating ...
Optimum power control for transmitter cooperation in OFDMA based wireless networks
(IEEE, 2011)
For a cooperative orthogonal frequency division multiple access (OFDMA) system with two transmitters (TXs), and full channel state information (CSI), we obtain the optimal power allocation (PA) policies which maximize the ...
Enabling cooperation, resource allocation and receiver selection across cells: complementary fractional frequency reuse
(IEEE, 2013)
For a multi-cell multiple access channel, we develop a comprehensive cooperative communication framework: we propose a novel complementary fractional frequency reuse (FFR) strategy tailored specifically for pairwise user ...
Resource allocation in the finite blocklength regime under PAoI and delay violation constraints
(IEEE, 2023-08-27)
URLLC (Ultra-reliable low-latency communication) is one of the more challenging modes for 5G for resource allocation (RA). Most of the previous studies for RA for wireless access in URLLC assumed known packet arrival ...
Delay tolerant cooperation in the energy harvesting multiple access channel
(IEEE, 2016)
We consider the optimum transmit scheduling problem for a two user energy harvesting cooperative multiple access channel. We assume a slotted model where energy harvests in each slot are known a priori. We propose a delay ...
