M2M SCADA

WSN RFID

IoT

SCADA (supervisory control and data acquisition)• SCADA is a system that

operates with coded signals over communication channels so as to provide control of remote equipment (using typically one communication channel per remote station).

M2M (machine-to-machine communication)

• Machine to Machine refers to technologies that allow both wireless and wired systems to communicate with other devices of the same type.

WSN (wireless sensor networks)• A wireless sensor network (WSN)

are spatially distributed autonomous sensors to monitor physical or environmental conditions, such as temperature, sound, pressure, etc., and to cooperatively pass their data through the network to a main location. The more modern networks are bi-directional, also enabling control of sensor activity.

RFID (radio frequency identification)

• Radio-frequency identification (RFID) is the wireless use of electromagnetic fields to transfer data, for the purposes of automatically identifying and tracking tags attached to objects.

Devices: Popular Platforms• Atmel AVR (Arduino)• ARM Cortex M (ARMmbed, Contiki, RiotOS,FreeRTOS)• ARMv7+ (Linux,Windows)• Intel/AMD (Linux,Windows)

Connection: WSN Protocols• PAN/LAN:• Conventional: WiFi, BLuetooth• Low-power: ZigBee, Xbee, BLE, 6LowPAN, Thread

• WAN:• Conventional: SMS, Cellular Data (GPRS/EDGE/3G), Satellite• Low power: ???

Connection: M2M Edge Protocols• Conventional:• HTTP• AMQP• OMA MDM

• Constrained:• CoAP• MQTT (SN)• OMA LWM2M

CoAP (constrained application protocol)

• Constrained Application Protocol (CoAP) is a software protocol intended to be used in very simple electronics devices that allows them to communicate interactively over the Internet. It is particularly targeted for small low power sensors, switches, valves and similar components that need to be controlled or supervised remotely, through standard Internet networks.

LWM2M (Lightweight M2M)

• OMA Lightweight M2M is a protocol from the Open Mobile Alliance for M2M or IoT device management.
