Experimental evaluation of multi-PHY 6TiSCH networks

The architectural design of Wireless Sensor Networks (WSNs) for the Industrial Internet Things (IIoT) applications requires careful planning and selection an appropriate operational strategy. Harmonization standards is crucial to ensure easier certification commercialization IIoT solutions. ongoing research activities are directed toward designing agile, reliable, secure transmission technologies protocols. Recently, Time Slotted Channel Hopping (TSCH) standardization bodies have started consider support multiple physical layers thus accommodating a wide range applications. This paper presents results extensive experimental measurement campaign study performance 6TiSCH (IPv6 over TSCH mode IEEE 802.15.4e) network while supporting (PHYs). For purposes, all experiments were performed on OpenMote-B hardware. These devices equipped with Atmel AT86RF215 dual radio transceiver implementing 802.15.4g. evaluation provided following metrics: formation time, Packet Delivery Ratio (PDR), latency, duty cycle. Results encouraging, particularly in terms high PDR tested PHYs. Performance indicates importance proper node positioning, link quality estimation parameters. Moreover, collected create dataset that provides insights into PHYs' their potential indoor networking.
