Secure Data Transmission In AODV Routing Protocol

Secure Information exchange in a network of mobile and wireless nodes without any infrastructure support such networks are called as adhoc networks. A Mobile adhoc network (MANET) is multi-hop, mobile, infrastructure less wireless network which is capable of independent operation. In this paper we have been discussing some of the basic routing protocols in MANET like Destination Sequenced Distance Vector(DSDV), Dynamic Source Routing(DSR), Adhoc On Demand Distance Vector(AODV) and Zone Routing Protocol(ZRP). Security is one of the principal issue in MANETs as they are infrastructure-less and independent. Therefore, in manet having security needs, there must be two considerations kept in mind: one to make a data transmission. Our endeavour in this paper would focus on achieving the routing and secure data exchange. In this course, we have designed the Ad Hoc on Demand Routing Protocol (AODV) using asymmetric cryptographic algorithm such as RSA . Which is more efficient as well as we have implemented the security technique so that we can prevent the data loss at the time of transmission.
