MANET is an accumulation of portable nodes that are equipped for imparting each other by means of a remote connection. MANET can frame at wherever necessary without any fixed infrastructure. There are sure parameters those are identified with the execution of the MANET i.e. routing, throughput, packet drop, delay and so forth. For secure data transmission cryptographic mechanisms are used and routing should be done dynamically so that nodes could easily find the shortest path for data delivery from source to destination and Private Key Generator (PKG) is used for generating keys for performing encryption and decryption of data. In this paper, we proposed a cryptographic strategy for generating the keys and for dynamic routing multi-mode routing algorithm is proposed and I-AODV protocol is also used which identifies the shortest path and allows nodes for data transfer and another strategy is proposed which mitigates the packet drop by presenting a 2ACK plan with sorting calculations.
