Wireless devices are increasingly in the congestion of the Internet highway. Is there a way out?

(03-11-2021) With so many wireless devices, wireless networks are becoming increasingly saturated and quality is compromised. In his doctorate, Irfan Jabandžić looks for solutions to optimize the use of wireless networks.

The possibilities within wireless communication are constantly expanding with new technologies and standards, and the number of connected devices is growing exponentially.

Consequently, the radio spectrum is becoming increasingly saturated, leading to suboptimal use of the spectrum and problems between different types of technologies.

"Licensed frequencies are severely underutilized, both in time and geographically. And license-free bands are becoming congested and wireless networks are experiencing increasingly severe performance degradation," Irfan explains.

"In my doctoral research, I propose solutions to enable wireless networks to be more optimally utilized," Irfan continues.

Specifically, he proposes the following solutions that will enable wireless networks to be more optimally utilized in the future:

  • New models for dynamic spectrum management in licensed and unlicensed bands
  • Design and implementation of a Medium Access Control (MAC) layer that supports mandatory MAC functionality and provides capabilities for dynamic spectrum sharing. [MAC is the sublayer that controls the hardware responsible for interacting with the wired, optical or wireless network]
  • Design and implementation of a Dynamic Distributed Multi-Channel Time Division Multiple Access (DDMC-TDMA) scheduling protocol.
  • Development of two spectrum sharing techniques within satellite communications.
