Spectrum Optimization of Low Power Wide Area Network Utilization in Smart Cities

Abstract

The discovery of this great technology known as  Low Power Wide Area Networks (LPWANs) has  significantly altered the way we live in a positive  way. It is a technology with low power and long range capabilities with impacts that cannot be  overemphasized. The impacts range from making  cities better with quality living, the environment  with quality air and humidity, efficient waste  disposal systems, smart metering systems, and  traffic free road management to more efficient  transportation. Our research focused on the  optimization of the unlicensed spectrum occupied  by LPWANs using cognitive radio and its utilization in smart cities. In this research, we  proposed the spectrum sharing model and carried  out our simulations using MATLAB. We  discovered that the spectrum sharing model  brought about an increase in channel capacity and  a decrease in latency, which are basic parameters  that determine the performance of the spectrum.  After the research, there was a significant  improvement in spectrum performance leading to  higher quality of service (QoS).
