Mobile Ad-hoc Network is group of wireless mobile d\nevice with restricted broadcast range and no use of base Infrastructure. The secure routing model helps for reduced honest elicitation and free riding problem. The term honest elicitation me ans it forward high recommendation for\nmalicious node in order to avoid itself. It means the high recommendation for colluding\nmalicious node. When operating in hostile or suspicious setting, MANETs require privacy and communication security in routing protocol. In this paper we present the type of attacks and operation on network layer with routing protocol technique i.e. based on an on-demand location based anonymous MANET routing protocol called SMRT(secure MANET routing technique with trust model) that achieves security and privacy against insider and outsider adversaries
