Similarity detection for smart and transparent long-range IoT relaying
Résumé
LPWAN refers to highly energy-efficient wireless communication over very long distances. Nonetheless, even with the increased range, 1-hop connectivity can be difficult to achieve in real-world deployment scenario. Especially for remote and rural areas where density of gateways is low and where devices/gateway are usually deployed for a specific application. Therefore, a smart and transparent 2-hop approach has been proposed in a previous work to leverage these connectivity issues. This article extends this approach with similarity detection features in order to (i) reduce the power consumption when waking-up to relay packets and (ii) reduce the radio activity time when running under duty-cycle regulated constraints.
