A station in a network forwards incoming packets by placing them on its shortest output queue. What routing algorithm is being used?

in classical (FIXED) network we use hot potato routing.... how about mobile Network (AD-HOC or Cellular)?

hot potato routing.

hot potato routing algorithm

The Dijkstra's algorithm used to calculate the SPF tree is CPU intensive that found in protocol  called OSPF protocol

Open Shortest Path First (OSPF) routing protocol

Deflection routing, also known as hot potato routing, is a routing strategy for networks based on packet switching which can reduce the need of buffering packets.
