Survey of various Active Attacks in MANETS

Networks have flourished due to the advent of new technology. There is a mushroom growth in technology and day to day needs for communication which was never experienced before. A Mobile Ad hoc Network (MANET) is a system of wireless mobile nodes that dynamically self-organize in arbitrary and temporary network topologies. People and vehicles can be internetwork in areas without a preexisting communication infrastructure or when the use of such infrastructure requires wireless extension. Various attacks needed to be detected on order to secure the wireless ad-hoc network. In this paper we are discussing various active attacks.
