2.3.3 Mesh Networks
The Tree topology is available in the IEEE 802.15.4 and JenNet protocols (in ZigBee
PRO, it is enhanced to a Mesh topology). It is suitable for larger networks and higher
traffic levels than the Star topology, but lacks the flexible routing of the Mesh topology.
A Mesh network contains the full range of node types - Co-ordinator, Routers and End
Devices. Any routing node (Router or Co-ordinator) can communicate directly with any
other routing node within radio range. However, an End Device can only communicate
directly with its parent. When sending a message between two nodes that cannot
communicate directly, the message is routed via intermediate routing nodes.
However, in a Mesh network there may be more than one possible route between the
source and destination nodes. A simple Mesh network is illustrated in

number of alternative
routes are available
