Abstract: Ad hoc networks provide flexible and adaptive networks with no fixed infrastructure and dynamic topology. Mobile ad hoc networks (MANETs) consist of a collection of wireless mobile nodes which dynamically exchange data among themselves without the reliance on a fixed base station or a wired backbone network. MANET nodes are typically distinguished by their limited power, processing, and memory resources as well as high degree of mobility. In such networks, the wireless mobile nodes may dynamically enter the network as well as leave the network. Mobile ad-hoc network is a group of two or more devices or nodes with the capability of communication and networking. It is an infrastructure less network. Such network may operate by them or may be connected to a larger internet. Due to its mobility and self-routing capability nature, there are many weaknesses in its security. The security of the network from various attacks is an important issue in MANET application now days. Due to the dynamically changing topology, open environment and lack of centralized security infrastructure, a mobile ad hoc network (MANET) is vulnerable to many attacks. This paper focuses on mobile ad hoc network's routing vulnerability and analyzes the network performance under Distributed Denial of Service MANETS.
