Joining 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).
Network Address The 16-bit address assigned to a node after it has joined to another
node. The coordinator always has a network address of 0.
Operating Channel The frequency selected for data communications between nodes. The
operating channel is selected by the coordinator on power-up.
Energy Scan 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.
Route Request Broadcast transmission sent by a coordinator or router throughout
the network in attempt to establish a route to a destination node.
Route Reply 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.
Route Discovery 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 Stack 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 spec-
ification.
For example, the mesh and routing capabilities available to ZigBee
solutions are absent in the 802.15.4 protocol.
