Zigbee Router

A Zigbee Router can route network traffic from other nodes, and also send its own data. For this reason Routers must be continually powered so that they receive any messages for routing. When a Router starts, it looks for a Coordinator or Router nearby and attempts to join it.

Routers are responsible for:
 * Finding and Joining the “correct” network
 * Perpetuating Broadcast Messages across the network
 * Participating in routing, including discovering and maintaining routes
 * Allowing other devices to join the network (if permit-join enabled)
 * Storing packets on behalf of sleeping children
