A gathering-based routing protocol (GRP) for mobile ad hoc networks is presented. The idea is to rapidly collect network infor-
mation at a source node at an expense of a small amount of control overheads. The source node can equip promising routes on the basis
of the collected information, thereby continuously transmitting data packets even if the current route is disconnected. It results in achiev-
ing fast (packet) transfer delay without unduly compromising on (control) overhead performance.

Since all nodes in the mobile ad hoc networks can be
mobile and communicate with one another either directly
or through intermediate nodes with no fixed infrastructure,
it is necessary to design an efficient routing protocol .
Proactive routing protocol (PRP) requires every node to
maintain full routing information, while reactive routing
