AODV Simulation code in NS2

How to simulate AODV Protocol using NS2 code

What is AODV Protocol?TCL Script for AODV simulation in ns2.

AODV refers to An on-demand routing protocol for wireless a network that uses traditional routing tables to store routing information.AODV protocol uses timers at each node and expires the routing table entry after the route is not used for a certain period of time.We have successfully delivered more than 50+ AODV Protocol Simulation in ns2 Project to B.E/B.Tech/M.E/M.Tech and PhD Scholars.Get in touch with us for customized AODV Protocol Projects.

Characteristics of AODV Protocol:

  • Multihop.
  • Low power
  • Auto configured.
  • Dynamic
  • Autonomous.
  • Peer-to-peer.
  • Zero-administration.

Benefits of AODV Simulation using Ns2 :

  • Wireless data rates.
  • Additional security exposure.
  • Scalability.
  • Non-ubiquitous coverage.
  • Power budget vs latency.
