Paper Presentation on Route Discovery Method

Introduction to  Route Discovery Method:

It is essential for the routing protocols present inside the MANETs to follow the route invention process. The DSR can create an investigation relating to this route targeted to the destination initialized from the source which is needed to pass on few packets. In the whole method if it’s recognized and regarded for the fresh route then the packets that are published towards the destination using similar path and the communication method. If the source being failed to recognize the current path then the DSR sends the request towards the nodes in order to validate the path.

Usually the path request is forwarded in the form of packet that is termed as the RREQ-route request packet furthermore as this specific packet is sent towards the whole nodes situated in the network. The most important attributes like the source and the IP address of target are  preserved by the RREQ in the form of single request id which is present by the sender.

By the whole method if  every node determines the dummy path request then immediately it will be occurred to be unimportant and after that it can investigate that whether they are related to the specified targeted nodes. The unicast function that is troublesome is administrated so as to forward the RREP messages to the source instead of sending the message to complete the whole network.

In the transmission method while performing the unicast function every node is able of changing the path at the side of its route cache.
