Major challenges of Mobile Adhoc Networks

In the unknown environment of network the security the major issue for safe communication between the nodes.In such networks a lot of active and passive attacks are done by the attackers in groups in the data packets and routing messages.Mobile Adhoc networks are such type of networks which does not have any centralized authentication and the nodes communicate with each other.In MANET security plays a vital role for safe communication.The focus is given on security of Mobile Adhoc Networks.MANET is open network which is available for the malicious and trustworthy users to communicate.The MANET has to design a robust solution which deals with such type of malicious attackers so that a health network transmission takes place between trustworthy nodes.The Mobile Adhoc Networks are the network which works in isolation along with the wired infrastructure.This elasticity of MANET is its biggest strength but it is also a big vulnerability for security issues.In paper we will discuss the active and passive attacks including black hole attacks, spoofing, warm hole, flooding and traffic monitoring, traffic analysis and eavesdropping respectively.
