Attacks Analysis in Mobile Ad Hoc Networks: Modeling and Simulation

The present work is dedicated to study attacks and contremusure in MANET. After a short introduction to what MANETs are and network security we present a survey of various attacks in MANETs pertaining to fail routing protocols. We also present the different tools used by these attacks and the mechanisms used by the secured routing protocols to counter them. Our work ends with a proposal analytical modeling to model some of these attacks like cooperative Blackhole, Blackmail, Overflow, Selfish and a simulation of these attacks by using a simulator network named ns2.
