Robust Security Solution to Countermeasure of Malicious Nodes for the Security of MANET

Abstract-A MANET is an infrastructure-less type network, which consists of number of mobile nodes with wireless network interfaces In order to make communication among nodes, the nodes dynamically establish paths among one another the nature and structure of such networks makes it attractive to various types of attackers. Security is a major concern for protected communication between mobile nodes. In this work we have proposed a method to study effect of different attacks on MANET and then analyzed the system efficiency of the network using different routing protocols. Finally the work is extended to countermeasure the effect of these attacks by providing security keys to each node to make them less vulnerable to the attacks. The proposed method is based on the improved routing protocols to increase the system efficiency and security
