Demand of infrastructure less, self-working, self-configuring, communication networks have led to the formation of mobile Adhoc networks (MANET). Manet is extraordinarily valuable over ancient networks in damaging conditions. In Manet all mobile devices work enjoyably for route discover and knowledge transmission. thanks to its broadcast nature of transmission, and cooperative model of operating, routing the traffic may be a tedious task in Manet. Routing protocols square measure perpetually targeted by attackers to wreck network. Routing protocols in Manet ought to be strong against completely different security dangers. Adhoc on-demand distance vector routing (AODV) protocol typically used and studied within the territory of mobile adhoc networks. so as to stop Manet from hole attack a replacement methodology is planned. during this work, hole attack in Manet is detected and prevented by victimisation Hop Count, Reverse Trip Time and Link Length methodology. consistent with the theme, hop count specifies the particular reverse trip time from supply to destination. to seek out the presence of tunnel, the supply can compare calculated reverse trip time with actual reverse trip time and to verify the presence of tunnel, the supply can compare calculated link length with actual link length of the links in ways. This theme provides a security to mobile spontaneous networks from each short still as long hole tunnels. Networksimulator is employed to gauge the performance of mobile spontaneous network. The simulation results show that the planned theme outperformed in terms of output and packet delivery quantitative relation
