Detection and Prevention of Malicious Packets Dropper in MANET Using Diffie-helman Packets Exchange Approach

Mobile Ad hoc network is one of the wireless networks that is more popular nowadays due to its application suitability. MANET network has a role to play in different fields such as the military. Backup service also is one of the important applications of MANET (tragedy, recovery, quick diagnosis or record handling in the hospital). It is worthy also to mention the vulnerability of MANET. Providing MANET security is not an easy task due to its dynamic nature and lack of central control point. In MANET routing protocols are needed to help discovering routes. AODV protocol is one the popular protocols used in route discovery process while routing packets to the intended destination in MANET, but AODV is also prone to well-known packet dropper attacks. MANET is prone to so many kinds of attacks that undermine network performance. Multiple strategies and mechanisms have been proposed to tackle those attacks in terms of improving network performances and network reliability, but still there is a need of strong better mechanism in MANET in order to provide an even better defence from attacks.
