Mobile Ad hoc Networks are assortment of mobile terminals or nodes, allowing no stationary infrastructure and centralized administration. A performance evaluation of routing protocol is very cumbersome due to various metrics involving dynamic topologies, mobility, routing limited resources, security etc. In this paper, various existing routing protocols were reviewed. It has been analyzed that efficiency of existing routing protocol degrades in the presence of attacks. Keeping in various attacks reports in literature and the protocol security algorithm; this paper attempts to review all such secure routing protocols comparing their relative metric and requirements.
