The existence of a reliable routing is one of key and significant challenges in mobile ad hoc networks. In this paper, a hierarchical routing protocol (HRP) is presented which is made of hybrid architecture combining reactive and proactive protocols. The objective of the proposed protocol is to reduce the end to end delay and routing overhead. The presented protocol provides a hierarchical routing protocol using clustering mechanism and considering the CBRP protocol. For reduction of delay, gateway nodes have a routing table as cluster heads. In evaluation of performance simulation results, it is shown that the proposed protocol has better efficiency than DSR and AODV routing protocols.
