Abstract
In recent years, extensive research has been conducted on Internet of
Things (IoT). Wireless Smart Ubiquitous Network (Wi-SUN) has gained
considerable attention as a wireless communication standard for IoT.
Wi-SUN Field Area Network (Wi-SUN FAN) is a technical specification of
Wi-SUN that can be implemented in both indoor and outdoor IoT
communication infrastructure with multi-hop routing. Although Wi-SUN FAN
version 1.0 (Wi-SUN FAN 1.0) has been standardized by IEEE 2857-2021,
there have been no studies or reviews conducted on the transmission
performance of Wi-SUN FAN 1.0 regarding transmission success rate and
delay time using computer simulations and experimental evaluation
environments involving actual devices. In this study, the specifications
of the Wi-SUN FAN are reviewed, and the fundamental transmission
performance, such as average transmission success rate and average delay
time, is measured using computer simulation as reference data. An
experimental evaluation environment involving actual devices is
developed to validate the characteristics evaluated by computer
simulation. The characteristics determined by the computer simulation
and experimental evaluation environment are in good agreement. Using the
validated simulator, we evaluate the transmission performance in the
wireless IoT environment with one border router and 100 routers randomly
arranged in a flat square field with 4,000 m on a side. The average
transmission success rate is approximately 1 at 1.00 ×
10–1 s–1 or less. Consequently,
Wi-SUN FAN 1.0 can communicate with a higher transmission success rate
even when transmitting frequent IoT-data, which is once every ten
seconds.
