Multi-mode routing mechanism with cryptographic techniques and reduction of packet drop using 2ACK scheme MANETs

Abstract

A mobile ad hoc network (MANET) is an accumulation of portable hubs that are equipped for imparting information to one another by means of a remote connection. A MANET can be positioned wherever necessary without any fixed infrastructure. There are certain parameters which are important to the execution of a 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 can easily find the shortest path for data delivery from source to destination. A private key generator (PKG) is used for generating keys for performing encryption and decryption of data. In this chapter, we propose a cryptographic strategy for generating keys and for dynamic routing a multi-mode routing algorithm is proposed. An ad hoc on-demand distance vector (AODV) protocol is used which identifies the shortest path and makes nodes available for data transfer. Another strategy is proposed which mitigates packet drop by presenting a 2ACK plan with a sorting calculation.
