A mobile ad hoc network is a kind of wireless network which is a self configuring network of mobile routers connected by wireless links. Mobile Ad-hoc NETwork (MANET) has dynamic topology. Self configurability and easy deployment feature of the MANET resulted in numerous applications in this modern era. This paper is a survey of security factors and critically analyze by most of the routing protocols which are reported in the available literature. This will help in having a wider understanding of the problem domain and can also be used to develop or some new or to extend already proposed schemes.
