OMNET++ AODV CODE – What is AODV?When AODV is Carried out?Sample OMNeT++ AODV CODE?

AODV Refereed as AD Hoc On Demand Distance Vector routing protocol.It is designed to carry Ad Hoc Mobile Network.AODV is a reactive protocol which means they are created only when required.AODV is a relative of the Bellman-Ford distant vector algorithm, but is adapted to work in a mobile environment.Download sample OMNeT++ AODV Code.

Control messages used in AODV:

  • Route request.
  • Route reply.
  • Route error.
  • Hello message.

These are the four different control messages used in AODV routing protocol.

Advantages of carrying OMNeT++ AODV CODE:

  • Reduces transmission for system wide flooding.
  • Reduced congestion.
  • Better robustness.
  • Reduced processing requirement.
  • Provides better scalability.
  • Active discussion about internet gateways.

Features of AODV routing protocols:

  • It eliminates route table updates for routes that are not used.
  • Even more localization for topology changes if distance vector.
  • AODV uses network-wide RREQ, unicast RREP along reverse oath to source of the request.
  • Route discovery broadcasts.
  • ICMP unreachable only after the route discovery attempt.
