Abstract: Mobile Ad - Hoc Networks (MANETs) are recognised as a key emerging technology for use whenever cellular communications are either infeasible, inefficient, or cost - ineffective. MANETS are composed of nodes that are arranged in a self ? organizing manner, without a central device like a switch or router. The nodes communicate with each other over wireless links and cooperate in a distributed fashion. Smart phones are the most ideal network nodes in many of the scenarios where traditional networks are not available. But it is not as easy and straightforward to build a secure network with them. In this paper, we extensively use existing possibilities to build a secure MANET. The designed MANET has been built on an NS3 simulator, with the base protocol being Ad - hoc On - demand Distance Vector (AODV) and message encryption done by using RSA Algorithm. Therefore, we discuss our implementation of the Secure AODV protocol extension using RSA encryption.
