Joint Optimization of Wireless Network Energy Consumption and Control System Performance in Wireless Networked Control Systems Authors:Şadi, Yalçın; Ergen, Sinem Coleri
Publisher and Date:(IEEE-INST Electrical Electronics Engineers Inc, 2017)Communication system design for wireless networked control systems requires satisfying the high reliability and strict delay constraints of control systems for guaranteed stability with the limited battery resources of sensor nodes despite the wireless networking induced non-idealities. These include non-zero packet error probability caused by the unreliability of wireless transmissions and non-zero delay resulting from packet transmission and shared wireless medium. In this paper we study the ...
Minimum Length Scheduling for Discrete Rate Based Full Duplex Wireless Powered Communication Networks Authors:Iqbal, Muhammad Shahid; Şadı, Yalçın; Ergen, Sinem Coleri
Publisher and Date:(Springer, 2019)In this study, we consider a wireless powered communication network where multiple users with radio frequency energy harvesting capabilities communicate to a hybrid energy and information access point in full duplex mode. We characterize an optimization framework for minimum length scheduling to determine the optimal rate adaptation and transmission scheduling subject to energy causality and traffic demand constraints of the users considering discrete-rate transmission model. We first formulate ...

Publisher and Date:(IEEE, 2019)The dramatic growth of machine-to-machine (M2M) communication in cellular networks brings the challenge of satisfying the quality of service (QoS) requirements of a large number of M2M devices with limited radio resources. In this paper we propose an optimization framework for the semi-persistent scheduling of M2M transmissions based on the exploitation of their periodicity with the goal of reducing the overhead of the signaling required for connection initiation and scheduling. The goal of the ...
