Studies on the Secure Routing Protocols of Mobile AD hoc Networks

A mobile AD hoc network (MANETS) is a collection of mobile nodes which can dynamically form a temporary network without using any existing network infrastructure or centralized administration. Mobile ad hoc networks (MANETs) bring great challenges in security due to its high dynamics, link vulnerability, and complete decentralization. With routing being a critical aspect for MANETs, existing routing protocols, however, are not sufficient for security requirements. Limited bandwidth and mobilityrequire that ad hoc routing protocols be robust, simple, and energy conserving. This paper firstly analyzes the routing attacks of mobile Ad hoc networking, then elaborates and compares some ad hoc secure routing protocols, at last points the future researches.
