Abstract
In conventional ad-hoc networks using reactive routing protocols the route between the source node and the destination node is not updated until the route is actually broken. In response to predetermined events a request for updated route message can be sent to the destination node to determine if another route exists between the source node and the destination node. A reply to the request for updated route can be provided by either the destination node or by a node which has a cached route between the source node and the destination node. This updated route request scheme can be implemented in networks which use source routing and networks which use distance vector routing.
