Abstract:
In Mobile Ad-Hoc Networks (MANETs) Security is an important issue in order to provide protected communication between mobile nodes in hostile environment. The unique characteristics of (MANETs) pose a number of nontrivial challenges to security design such as open peer-to-peer network architecture, shared wireless medium, stringent resources 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. Here proposed an efficient Symmetric-key algorithm (AES) that provides complete security solution and encompass all three security components of prevention, detection, and reaction.

Keywords: Mobile ad-hoc network (MANET), ad-hoc on-demand distance vector routing (AODV), advanced encryption standard (AES), confidentiality.
