The reactive routing protocols
The reactive or else the on demand routing protocols are some what different and are varied from the table drive routing protocols. It is already been proved that they will not sustain any type of the static routing information as well as they are entirely dynamic in nature relevant to that of the routing information. Depending on the specific demands the route towards the target is been constructed. The first and the major task of this routing protocol is they will verify the current routing information and if the information is similar then it will be utilized and if it is not same then it will ask for some requests towards the networks in order to implement the routes towards the destination.
The routing information which is been reserved with this particular protocols is not static and in the ongoing process if at all the route is identified to be inactive for some extent, then it will expire then the new routes are been implemented based on the requirements and then these specific protocols are been considered as the on-demand routing protocols. This protocols are if soft state which is been sustained all over the routing tables. The reactive routing protocols are having two different types of the routing protocols such as the DSR-dynamic source routing as well as the AODV- Ad Hoc on demand vector which are been explained in detail as follows.
