MORA: a movement-based routing algorithm for ad hoc networks
... Routes are designed when they are needed, in order to minimize the communication overhead. When a node needs to send a message to another node, the sender needs to flood the network in order to find the receiver and determine a path to reach it. The flooding process can still use a significant amoun ...
