In wireless networking, On-Demand Multicast Routing Protocol is a protocol for routing
multicast
In computer networking, multicast is a type of group communication where data transmission is addressed to a group of destination computers simultaneously. Multicast can be one-to-many or many-to-many distribution. Multicast differs from ph ...

unicast
Unicast is data transmission from a single sender (red) to a single receiver (green). Other devices on the network (yellow) do not participate in the communication.

ODMRP creates routes on demand, rather than proactively creating routes as
OLSR does. This suffers from a route acquisition delay, although it helps reduce network traffic in general. To help reduce the problem of this delay, some implementations send the first data packet along with the route discovery packet.
Because some links may be asymmetric, the path from one node to another is not necessarily the same as the reverse path of these nodes.
