Mobile Ad-hoc Network (MANET) has been an active research area as it has the special features such as fast, dynamic and easy to deploy anywhere. Absence of central monitoring unit, MANET highly depends on mobile nodes reliability. This leads MANETs are more vulnerable to various communication security attacks. One of the main active attacks is Black hole attack, it is a denial of service attack and it drops entire incoming packets between one source to destination. The attempt is to focus on analyzing and strengthening the security of routing protocol Ad-hoc On Demand Distance Vector (AODV) for MANET. The Proposed Method PL2 has the modification done in AODV protocol for ensuring the security against the Black hole attack using NS2 Simulation.
