AODV Protocol CSE Reference Material

Introduction to AODV Protocol:

Nowadays Adhoc networks are in search of efficient applications and protocols and for this reason many multiple Adhoc routing protocols are proposed such as AODV, DSR and DSDV. This AODV- Adhoc on demand distance vector protocol is robust in nature which is totally against the different types of topology differentiations that are degrading the entire performance of communications. AODV is having the similar characteristics of DSR as well as DSDV protocols in which the route destinations are managed by making use of route information and sequences in order to exclude the loop problems.

In the ongoing process, AODV uses the sequence numbers that belong to DSDV in order to reduce the flooding that take place in routing process resulting in increasing the quantity, scalability as well efficiency that can carry and transfer the packets in a successful manner. In order to recognize the route destination, the different types of broadcasts will send an internal request to the RREQ- route request packets.

Until the fresh route information is gathered the neighbouring intermediate nodes will perform routing process. The RREP- Route Reply Packet is sent to the intermediate nodes towards its source node by copying the paths. In order to identify and explain the route information the different types of sequence numbers are utilized by AODV protocol which ensures the loop free routing.

Within the AODV protocol process, the routes are built upon the demands which are capable of breaking the entire nodes by adapting the different topology changes and mobility problems. In order to restrict and overcome the route problems AODV will make use of the route discovery zone which identifies the route destination.
