The basic thing for keeping communication between mobile nodes in a harmful environment is security. Due to changing topology of MANET, it is usable to both, pernicious attackers and proper network users. Within the existence of deadly nodes, one of the leading threats in MANET is to outline the robust security resolution that can keep MANET from certain routing attacks. Indeed, these outcomes are not fitting for MANET resource constraints, i.e., battery power and bounded bandwidth, since they prompt heavy traffic load to swap and changing keys. In the wireless MANET, one among security threats that is noted is to disclose and destroy the grey-hole attack. Grey-hole attack causes the harm in a network, and is very much problematic to find it in the network. In this paper, present results are measured and taken up the routing methods that are progressive.
