Wireless LAN(WLAN)
Forwards data from the BMS to the end devices and vice versa over the different networks of this architecture:
• The Wireless Mesh Network (WMN). Uses a multi-channel IEEE 802.11a MAC. Requires a solid channel assignment algortithm, setting up fixed links with a few selected neighbours, creating a wireless switched ethernet. This allows the introduction of known and well tested ethernet concepts in the WMN domain.
• The Sensor and Actuator Network (SANET). Uses IEEE 802.15.4 technology for the MAC layer. ZigBee doesn't support QoS and is not scalable enough for wireless building automation. Therefore, extra research is needed to solve these issues.
• The Wireless LAN (WLAN). Requires QoS-supprt, what could be implemented using the new IEEE 802.11e standard, or IEEE 802.11 g extended with some QoS schemes.
Network – data plane
• Monitors data from the end devices and takes the necessary actions. • Consists of different applications for the management of heating, ventilation and airconditioning, fire detection, access control, video surveillance, tracking of persons and equipment, etc.
• For high bit rate data, the BMS - data plane will request connections to the connection management with specific quality parameters such as framerate and resolution.
BMS – data plane
• Typical element management tasks: fault, configuration, performance, security and accounting management
• Capacity flow management tasks, processing connection requests from the connection management.
• Uses topology and network status information gathered from the distributed network control to determine the optimal way to route the connection.
• This optimal route for the connection takes the already established connections into account, thus realising bandwidth reservations.
Network management
• Responsible for the configuration of the device settings, e.g. frame rate and resolution of a camera, polling interval of a temperature sensor, sensitivity of a smoke detector, etc.
• Typically, the device control isn't intelligent but just executes the commands given by the device management.
• The Intelligent video control however changes the camera settings in an autonomous way. It can change the resolution and frame rate as a result of intelligent algorithms running on the camera (e.g. taking type of content or energy constraints into account).
Device control
• Low data rate devices such as sensors and actuators, equipped with a low-power RF module (e.g. IEEE 802.15.4).
• High data rate devices such as cameras, speakers and video screens, equipped with a high data rate RF module (e.g. IEEE 802.11).
• The end devices generally send their data to the BMS and vice versa, but some sensors may also send data directly to one or more actuators within the SANET, e.g. when the latency introduced when going through the BMS is too high.
