Secure communication for mobile Adhoc network using (LPIT) Lagrange polynomial and Integral transform with Exponential Function

Mobile adhoc network is collection of autonomous nodes that are frequently moving without the centralized control. Mobile adhoc networks are multi hop wireless networks without fixed infrastructure. Node frequently change topology, due to this type of behavior transformation of information from one node to another node is more complicated task. Decentralized nature of mobile adhoc network is more vulnerable to attack like denial of service (DOS) which consumes more bandwidth and resources. Security is major concern in adhoc network, so in this paper, we propose a new algorithm based on Lagrange polynomial and Laplace transform and inverse Laplace transform to enhance secure communication for MANET. This proposed algorithm provides security for transmission of information among node.
