Design and analysis of network Security system based on angle and Context free grammar methods for Precarious node detection and Secure data transmission in manet

Abstract

A group of mobile nodes linked together to perform a particular newlinecommunication task with no centralized control Conti et al 2007 is called a newlineMANET The greatest advantage in a MANET is the lack of infrastructure newlinewhich makes it easy for each node in the network to autonomously perform newlinedirect interactions with another node routing operations decision making and newlinedata alteration during the communication process newlineProvision of mobility for the nodes makes the nodes vulnerable to newlinenumerous attacks and malignity and there is a need to protect communication newlineamong ad hoc nodes Exploitation of the dynamic topology change itself to newlineincorporate security while routing is the most suggested approach to solve newlinethis problem. The designs of various security systems that are aware of the newlinechange in the location are the most desired techniques for a MANET In such newlinean attempt, there are four major protocols proposed in this research work newline newline
