Any time an input event occurs, perform a local calculation.
If one or more feasible successors are found in the topology table, take the ones with the lowest metric cost as the successors.
If no feasible successor can be found, make the route active and query the neighbors for a feasible successor.
Keep the route active until all queries are answered by reply or by the expiration of the active timer.
If the diffusing calculation does not result in the discovery of a feasible successor, declare the destination unreachable.
