In the network layer, Zigbee follows AODV routing scheme.
A short not on AODV:
= > It is an acronym for Ad-Hoc on demand Distance vector.
= > It is designed for both on demand and table driven protocols.
= > It defines three types of messages
(a) route request
(b) route reply
(c) route error message
= > It requires less memory space.
Hope this helps!
Hey there!
----------
The answer is AODV.
In the network layer, Zigbee follows AODV (Ad hoc On-Demand Distance Vector) Scheme.
→ Extra information :
⇥ Ad Hoc Networks or MANETs (Mobile Ad hoc NETworks) : Networks of nodes that just happen to be near each other.
⇥ AODV (Ad hoc On-demand Distance Vector) : It is a relative of the distance vector algorithm that has been adapted to work in a mobile environment, in which nodes often have limited bandwidth and battery lifetimes.
<> AODV has two phases :
(a) Route Discovery
(b) Route Maintenance
<> In these two phases, AODV defines three message types :
(i) ROUTE REQUEST (RREQ)
(ii) ROUTE REPLY (RREP)
(iii) ROUTE ERROR (RERR)
