An ARM-Compliant Architecture for User Privacy in Smart Cities: SMARTIE—Quality by Design in the IoT

Figure 5

Outline of some Functional Components (FCs) of the SMARTIE platform for the building management use case. Arrows indicate flows of information between FCs. HAMs (picture at the top) are IoT gateways with μ-C-powered boards (32-bit MIPS μC running at 80 MHz, with 16 configurable inputs/outputs) that support RS-232, RS-485, ZigBee, 6LowPAN, and Bluetooth connections. Although arrows only depict the case when sensors are associated with HAMs, IP-enabled sensors to directly communicate with the BMS or the platform. Sensors (images at the top-right corner) have a 16-bit μC that runs at 8 MHz and support 802.15.4/6LowPAN/CoAP.
