This recommended practice defines a protocol that routes packets in a dynamically changing IEEE 802.15.4 network with minimal impact from route management. The result is an extension of the area of coverage as the number of nodes increases. This recommended practice will facilitate the routing of packets in dynamically changing wireless networks. In particular, it will provide for automatic handling of route related capabilities such as the following: Discovery and addition of new nodes; Route establishment; Dynamic route reconfiguration; Re-establishment of broken/lost routes; Purging of inactive routes; Real time link status information exchange; Single hop appearance at the networking layer (not breaking standard Layer 3 mechanisms); Support for broadcast; Support for multicast; Frame forwarding Amendment Standard - Active. This amendment to IEEE Std 802.15.10 fully defines how the addressing and route information (already defined in the recommended practice) are to be used by the routing modes (also currently defined in the recommended practice), including at least the following: end-to-end (E2E) acknowledgment from mesh route in non-storing mode; peer-to-peer (P2P) routing using a combination of up/down routing in non-storing mode; on-demand P2P routing for E2E acknowledgment in non-storing mode; on-demand path storing when sending unicast in non-storing mode.
