Effect Analysis of Black Hole Attack of AODV Protocol in MANET using Table Driven Approach

Abstract

ABSTRACT MANET is a wireless network that allows user to communicate and transfer information without using any infrastructure and irrespective of their location. They are very useful for home uses, for military uses etc. Though they are very useful in day to day life, major threats are also there to attack over it; some of them are wormhole attack, denial of service, eavesdropping etc. Black Hole attack is one of the major attacks on MANET. In this research paper, the effect of black hole over the network is evaluated by varying certain values of the network like number of nodes, pause time, area and speed. This paper shows that despite of presence of black hole in the network, the increament and decrement of certain values also affect the performance of MANET. For this, a table has been used which stores all the values of the parameters with and without black hole in the network obtaining by variations among the several values. Before and after values are stored which are afterwards will use for the analysis of the performance of the protocol. The protocol used in this paper is AODV (Ad-Hoc on Demand Distance Vector) protocol.
