2 Abstract: A Mobile Ad-hoc Network (MANET) is a collection of mobile nodes which moves frequently without the aid of any centralized network and they are self-organized and self-configurable network by a collection of mobile nodes. Due to mobility of nodes, there introduces frequent link failures which lead to increased routing overhead and introduce delay during data transmission. These problems put in force to design an efficient routing protocol by combining NCPR with modified ZRP (Zone Routing Protocol) to reduce the routing overhead, power and delay. Reactive Routing protocol causes less overhead when compared to Proactive routing protocol. In the existing system Neighbor Coverage based Probabilistic Rebroadcast protocol (NCPR) is used for reducing routing overheads in MANETs. As NCPR is a reactive routing protocol there introduces some delay and high power consumption, so it is necessary to combine the modified hybrid routing protocol (ZRP) along with NCPR to enhance the network performance. In our proposed system since both proactive and reactive concepts are there it perform better for route discoveries. The simulation result shows that the delay and power has been reduced by using modified ZRP along with NCPR.
