The Multipath On-demand Routing (MOR) protocol is a protocol to connect nodes in wireless sensor networks.
MOR lessens the disadvantages of on-demand routing in wireless sensor networks by having the likely targets of communication perform an initial broadcast.
There are many advantages to having multiple routes when possible, including Each node in MOR remembers all next-hop nodes that are closer to a given destination for which a route exists.
It then sends successive packets to each such node in round-robin fashion.
This allows automatic and graceful recovery from occasional localized congestion as well as longer-term reasons for node unavailability.
