Security in MANET routing tables with FMNK cryptography model

MANET-Mobile Ad hoc Network is an assembly of movable nodes which pass on information with each other by means of multi-hop wireless associates. As nodes travel often, it won´t be having an unchanging infrastructure as a result it is unsafe and will be inclined by various attacks. Each node has a finite interaction range, which will be behaves as a router to communicate the packets to another node. DOS (Denial-of-Service) attack, Flooding attack are some serious threats in MANET which causes data unsafety in MANET. The main problem in MANET is that, the routing tables which consists of each neighbour node information which maintained by the each node for the dynamic topology creation which is insecure. So to overcome this drawback, a optimized FMNK (Finger print Minutiae point non-invertible Key) algorithm is produced utilizing Biometric image models are introduced which can afford security and authentication. An optimized FMNK-SSL-AES-256(Finger print non invert able key Secure Socket Layer-Advance Encryption Standard) encryption algorithm is being introduced to encrypt the information applying a key to increase the security in MANET. Once the algorithm was developed the tables are protected with this proposed model and the message communication among nodes shown through NS2 tool. This showed the communication among starting node to end with minimum cost by dynamic calculation of Euclidian distance Model.
