SECURITY IN MOBILE AD HOC NETWORKS

Security has become a primary concern in order to provide protected communication between mobile nodes in a hostile environment. Unlike the wire line networks, the unique characteristics of mobile ad hoc networks pose a number of nontrivial challenges to security design, such as open peer-to-peer network architecture, shared wireless medium, stringent resource constraints, and highly dynamic network topology. These challenges clearly make a case for building multifence security solutions that achieve both broad protection and desirable network performance. In this article we focus on the fundamental security problem of protecting the data transmitting between two nodes in a MANET that is from wormhole attacks and find the solution related to this problem. We also identify the security issues related to this problem, various protocols (SRP) used in securing MANETs and overview of ongoing research in securing MANETs
