A TWO TIER APPROACH FOR PREVENTING BLACK HOLE ATTACK AND IMPROVING EFFICIENCY

Avinash Gada, Praveen Naik

Abstract: One of the most emerging and trending in the field of networking is secure routing to overcome many hindrances that are occurring in day to day lives. Thus providing efficient mechanisms for such networks is the most challenging one. MANET’s (Mobile Adhoc Networks) are a combination of several independent nodes without any fixed infrastructure, dynamic topology, battery constraints, and lack of centralized mechanism, because of its architecture/outlier they are more vulnerable to various kinds of passive and active attacks, such as black hole attack, grey hole attack, wormhole attack. Providing/Implementing a multi tier/two tier security mechanism helps in elevating such kinds of active attacks to some extent.
