Modified AODV Protocol Against Blackhole Attacks in MANET
Mobile Adhoc NETwork (MANET) consists of a collection of wireless mobile hosts without the required intervention of any existing infrastructure or centralized access point such as base station. The dynamic topology of MANET allows nodes to join and leave the network at any point of time. Wireless MANET is particularly vulnerable due to its fundamental characteristics such as open medium, dynamic topology, distributed cooperation and constrained capability. So, security in MANET is a complex issue. There are many routing protocols that establish the routes between the nodes in the network.
