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.

Download Sample source code for AODV Protocol simulation using Ns2.For customized AODV Simulation code in Ns2,Contact us for more detail information.

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.
