Internet of Paint (IoP): Channel Modeling and Capacity Analysis for Terahertz Electromagnetic Nanonetworks Embedded in Paint
arxiv(2024)
摘要
This work opens a new chapter in the 100,000 year-old concept of paint, by
leveraging innovations in nano-technology in the sub-THz frequency range. More
specifically, the groundbreaking concept of Internet of Paint (IoP) is
introduced along with a comprehensive channel model and a capacity analysis for
nano-scale radios embedded in paint and communicating through paint.
Nano-network devices, integrated within a paint medium, communicate via a
multipath strategy, encompassing direct waves, reflections from interfaces, and
lateral wave propagation. The evaluation incorporates three distinct paint
types to assess path losses, received powers, and channel capacity. Analysis of
path loss indicates a slight non-linear increase with both frequency and Line
of Sight (LoS) distance between transceivers. Notably, paints with high
refractive indexes result in the highest path loss. Moreover, burying
transceivers at similar depths near the Air-Paint interface showcases promising
performance of lateral waves with increasing LoS distance. Increasing paint
layer depth leads to amplified attenuation, while total received power exhibits
promising results when in close proximity to the Air-Paint interface but
steeply declines with burial depth. Additionally, a substantial reduction in
channel capacity is observed with LoS distance and burial depth, so
transceivers need to be close together and in proximity of the A-P interface to
communicate effectively. Comparing paint and air mediums, IoP demonstrates
approximately two orders of magnitude reduction in channel capacity compared to
air-based communication channels. This paper provides valuable insights into
the potential of IoP communication within paint mediums and offers a foundation
for further advancements in this emerging field.
