WM-Z1110) for Wireless Sensor Network system
Description
The transceiver module (WM-Z1110) forms a Wireless Sensor Network system (WSN)
with the sensor unit and the equipment control unit, as shown in Fig.2 .
WSN utilizes wireless mesh technology*.
* Xmesh technology by Crossbow Technology.
A wireless mesh network consists of a collection of nodes that communicate with each other
by ad-hoc routing.
A grid-like topology enables the signal to hop among different paths in order to circumvent
obstructions as it seeks and ultimately finds its target device.
These redundant communication paths enable a very high reliability.
Because multiple signal paths exist, the network can adjust to potential communication link
disruptions due to changes in the physical environment.
Once installed and powered, the transceivers automatically form a mesh network, and
the Xmesh's communication is virtually transparent to the system and end user.
