OSR: Advancing Multi-Hop Routing for LoRaWAN Mesh Networks in Maritime Scenarios
Conférence : Communications avec actes dans un congrès international
Reliable data acquisition and transmission from
ocean-deployed buoys are crucial for maritime applications.
However, wireless data transmission in such contexts faces
significant challenges due to limited buoy battery capacity, harsh
weather conditions, and potential disruptions from maritime
vessels. LoRaWAN technology presents a promising solution due
to its low power consumption and long-range communication
capabilities. Multi-hop routing can further enhance network
efficiency by enabling data relaying between buoys. However,
the standard LoRaWAN framework lacks native support for
multi-hop routing. Addressing this limitation, this paper presents
a novel multi-hop routing protocol called OSR specifically
designed for LoRaWAN mesh networks deployed in maritime
environments. The protocol’s effectiveness is evaluated through
a simulation model that accurately reflects the detrimental effects
of severe weather on data transmission. Key performance metrics,
such as packet delivery ratio, end-to-end latency, and energy
consumption are analysed. The results underscore the superiority
of OSR over
