As an emerging new technology a wireless communication allows users to access services electronically, wherever they might geographically be positioned. A MANET (M obile Ad Hoc Network )is a special wireless network without any fixed infrastructure and It has dynamic topology. In this paper we have discussed a new secure routing protocol named as minimized overhead and admsinistrator based secure routing protocol(MOAP) for data packets, which is signifiacndly different from existing routing protocol. We have reduced the amount of network activity for each node required to route a data packet. We have utilized our algorithm to implement this protocol and then simulate with diffentent test cases. Finally we have discussed how this protocol prevents various attacks which may jeopardize any wireless network.
