AODV

AODV is a networking routing protocol. The term AODV is an acronym for Ad-Hoc On demand distance vector. As mentioned before it is a routing protocol for the MANETs or Mobile Ad Hoc networks present in the networking world and other wireless Ad-Hoc networks that are working throughout the world in certain buildings or places. This routing protocol was established or developed by the combined effort of several different companies. These were Nokia, University of California, Santa Barbara and University of Cincinnati. The work on this protocol was done in the Nokia research centre, so that it could be test extensively.

It is a reactive type of routing protocol, which means that it will only generate a path between the source and the destination nodes on the request of the source nodes, thus allowing the nodes present in a network to enter or leave a specific connection whenever it wills, without disturbing the other nodes. Once the data link is established between the destination and the source, then it would remain active only as long as the data packets between the source and the destination continued to flow, that is, as soon as the flow of the data packets stop, the connection between the source and the destination close.

The way this routing protocol works is mentioned in the following material. In start when no connection are present between the source and the destination, then at that point the network is silent, however, when a connection is needed a request for the connection is sent by the source node, which is forwarded to the other nodes present in the network, when the message is being forwards a temporary route, back to the source node is also made, which takes back a message from the destined node to the source node, indicating that a connection can be established, however, in case no destined node is found the error message is sent to the source node and then the whole procedure begins again to find a destined node.
