Constrained IoT nodes are class-1 devices9 based on the Contiki operating system and using IEEE 802.15.4 radio.
Specifically, we used six TelosB (www.memsic.com/userfiles/files/Datasheets/WSN/telosb_datasheet.pdf),
20 Zolertia Z1 (http://zolertia.io/z1), and 10 OpenMoteCC2538 (www.openmote.com/hardware.html) constrained nodes.
SBC nodes are class-2 devices,9 typically running a Linux operating system and with multiple network interfaces.
