NI Wireless Sensor Networks
The NI WSN system is built on an IEEE 802.15.4 wireless mesh
network. The 802.15.4 radio in each NI WSN device provides for
low-power communication of measurement data across a large
network of devices. The NI-WSN software builds on top of that to
provide network configuration and reliable communication from
the host PC or PAC to the NI WSN-32xx nodes.
Mesh Networking
The NI WSN system consists of two types of devices: gateways and
nodes. Gateways act as the network coordinator, in charge of node
connection, message buffering, and bridging from the 802.15.4
wireless network to the wired Ethernet network. Nodes primarily
function as end nodes in the network to collect data and control DIO
channels, but can also be programmed as routers to relay data from
other nodes back to the gateway and host PC or PAC. Router nodes
also collect data and control DIO, but require significantly more
power. Use NI MAX to configure nodes as end nodes or routers.
Figure 2 shows a typical NI Wireless Sensor Network.
The gateways and nodes work together to form a mesh network.
The gateway maintains a list of nodes (by serial number) that have
been authorized for network access. When a node powers up, it
