Power Control in Wireless Systems: Algorithmic Approaches and Dynamic Modeling
Sara Riahi, Azzeddine Riahi · 2019
This paper introduces the necessary basics for understanding of wireless networks. We will present the different types of wireless networks, such as the cellular network, the WLAN, the WSN sensor network and give a brief overview of the associated communication standards such as LTE, WiFi and ZigBee. We will then describe the OSI model that is common to all these networks. We will then detail the classical communication chain, with particular emphasis on the physical layer and the transmission channel. We will also look at QoS indicators at the physical layer level. Finally, we will present the issues specific to wireless networks such as energy efficiency and improvement of QoS by power control.
