A Multi-Hop Cluster Based Routing Protocol for MANET

Cluster based routing protocols have the benefit of reducing routing overload and increasing performance in the transmission delay and throughput. In this paper, on the basis of CBRP we propose a new protocol called KHCBRP (K-Hop Cluster Based Routing Protocol) which enlarges the range of electing clusterhead to K hops and introduces the concept of metric of constraint degree to restrain the clusterhead election. KHCBRP also improves the routing discovery by integrating the inter-cluster on-demand routing and the intra-cluster table-driven routing, which can solve blindly "Broadcast" problem in CBRP and reduce redundant information and routing overload in the network. The simulation result shows that KHCBRP provides better performance in the MANET network of large scale and high mobility.
