The Route Discovery Process Literature Review

The route discovery process

The total number of the routing protocols which are present in the MANETs should follow the route discovery process. The DSR will make an investigation regarding the current route towards the destination starting from the source that is required to forward few packets. In the entire process if it is identified and considered as the non expired route then the packets are been broadcasted towards the target by making use of the similar route as well as the communication process. And if the source is not able to identify any type of the current route then the DSR will raise the request towards the nodes for the purpose of the valid route .

Generally the route request is been transmitted as the packet which is called as the RREQ-route request packet as well as this particular packet is been transmitted towards the entire nodes which are present within the network. The major attributes such as the source as well as the destination IP address are been maintained by the RREQ through the single request id that is been situated through the sender.

In the entire process if at all the node identifies the fake route request then it will be immediately happened to be unnecessary and it will even verify that they belongs to the desired destination nodes or not. The unicast operation which is difficult is been carried out in order to forward the RREP messages towards the source rather than transmitting the message in order to finish the total network. Within the process of transmitting as well as the performing the unicast operation each and every node is capable of updating the route along with its route cache.
