Implementation of AODV Protocol and Detection of Malicious Nodes in MANETs

Savithru Lokanath, Aravind Thayur

Abstract: Ad-hoc mobile networks are very dynamic, self-organizing; self-healing distributed networks which support data networking without an infrastructure. Instead of relying on a base station to coordinate the flow of messages to each node in the network, the individual network nodes forward packets to and from each other. Ad-hoc network is a self-organized, dynamically changing multi-hop network. All mobile nodes in an ad-hoc network are capable of communicating with each other without the aid of any established infrastructure or centralized controller. The user can use the network services efficiently and securely while moving. AODV (Ad-hoc On-demand Distance Vector) is a loop-free routing protocol for ad-hoc networks. It is designed to be self-starting in an environment of mobile nodes, withstanding a variety of network behaviors such as node mobility, link failures and packet losses. The AODV is a reactive protocol: the routes are created only when they are needed. It uses traditional routing tables, one entry per destination, and sequence numbers to determine whether routing information is up-to-date and to prevent routing loops.
