The process of a node becoming part of a ZigBee PAN. A node
becomes part of a network by joining to a coordinator or a router
(that has previously joined to the network). During the process of
joining, the node that allowed joining (the parent) assigns a 16-bit
address to the joining node (the child).
The 16-bit address assigned to a node after it has joined to another
node. The coordinator always has a network address of 0.
The frequency selected for data communications between nodes. The
operating channel is selected by the coordinator on power-up.
A scan of RF channels that detects the amount of energy present on
the selected channels. The coordinator uses the energy scan to
determine the operating channel.
Broadcast transmission sent by a coordinator or router throughout
the network in attempt to establish a route to a destination node.
Unicast transmission sent back to the originator of the route request.
It is initiated by a node when it receives a route request packet and
its address matches the Destination Address in the route request
packet.
The process of establishing a route to a destination node when one
does not exist in the Routing Table. It is based on the AODV (Ad-hoc
On-demand Distance Vector routing) protocol.
ZigBee is a published specification set of high-level communication
protocols for use with small, low-power modules. The ZigBee stack
provides a layer of network functionality on top of the 802.15.4
specification.
For example, the mesh and routing capabilities available to ZigBee
solutions are absent in the 802.15.4 protocol.
