TY - GEN A1 - Kaluza, Bennet T1 - BLE Periodic Advertising as an Alternative to BLE Mesh and Scatternets for Multihop Communication T2 - 20. GI/ITG KuVS Fachgespräch Sensornetze (FGSN 2023) N2 - Waldwächter 5G is a project about preventing damages to forests, for example by fire. For this case, sensors connected in a Bluetooth Low Energy (BLE) multi-hop environment are deployed to detect abnormalities. BLE is a widely spread wireless communication technology used for low power devices, such as smart home appliances or sensors. This paper presents two approaches for BLE multi-hop communication, BLE Mesh as a flooding based network primarily used for non-power-limited devices and BLE scatternets as a lose collective term for a lot of interconnected smaller networks. It then introduces the idea of a third possible option, a network topology based on a BLE 5.0 feature called Periodic Advertising (PA). The idea of an approach to PA meshes is explained and the advantages presented.
