How does the SmartSpace System work

A SmartSpace consists of spatially distributed autonomous sensors to cooperatively monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, motion or pollutants.

The enabling technology of smartspaces are tiny wireless sensors embedded in everyday objects to provide access to previously stranded data, identify and perceive users and their actions and goals, facilitate interaction with information sources, increase the rate of information interchange, support collaborative operations on shared data/knowledge representations.
The hallmark of SmartNetwork components is that they use a special hardware and firmware architecture with an extremely low power consumption (as far as 0,05 mW - 0,016 mA at 3V). (read more).


A SmartNetwork uses three types of nodes: Coordinators, Routers and End Device, with a requirement of one Coordinator per network. While all nodes can send and receive data, there are differences in the specific roles they play.


Coordinator is the device that establishes the network, coordinates routing, aggregates mote packets, publishes data to a host application and store information about the network, including security keys.


Routers are ultra low-power wireless transceivers that transfer data to and from associated sensors or actuators and use an onboard radio to send the packets to neighboring routers. These pass the packet on to other routers and, in a series of "hops" deliver the data to their destination. Routers can be added without disruption to the network.

End Devices

End Devices are tiny devices that include three basic components: a sensing subsystem for data acquisition from the physical surrounding environment, a processing subsystem for local data processing and storage, and a wireless communication subsystem for data transmission.
The number and type of each device in a SmartNetwork will vary depending on the size, complexity, and type of applications supported.
Multiple SmartNetworks can be deployed to cover all the places of interest.


All SmartNetwork devices (except the Coordinator) are battery operated
