A DETAIL STUDY ON VARIOUS SECURITY THREATS AND THEIR DEFENSE METRICS IN MOBILE AD-HOC NETWORKS

Abstract

 A mobile ad-hoc network (MANET) is a self-configuring infrastructure less network of mobile 
devices connected by wireless.  Mobile   Ad-hoc   Networks   are   the    new paradigm of wireless networks that 
are   capable of operating without the support of any fixed infrastructure. Routing is a core problem in 
networks for delivering data from one node to another node. Absence of infrastructure and dynamic nature of 
MANET invites intruder to launch attack. The   most    indispensable   service   of wireless network is security. 
In  this  paper,  we  have attempted  to  present  an  overview  of  various  security attacks and their Proposed 
solutions in MANET. We had given an overview of the various attacks at different layers followed by the 
measures taken to counter these attacks.
