Comparison of Different Methods for Gray Hole Attacks on AODV based MANET
Mehul Vasava · 2014
Abstract- Now a day, MANET security has become a big issue and one of the central attentions to the researchers. MANET is a network of wirelessly connected self configuring nodes which functions under the particular routing protocols. There isn’t any central administration or a fixed infrastructure in the MANET. Any node within the MANET can move to any other network at anytime or other nodes can also connect to the MANET. This makes MANET highly vulnerable for different attacks.This paper focuses on a GrayHole attack among the different types of attacks possible in a MANET. GrayHole attack is one type of active attack which tends to drop the packets during the routing from source to destination. This paper also includes thecomparison of different techniques to deal with the GrayHole attack. Key terms:MANET, AODV protocol, GrayHole attack 1.
