Abstract: Routing in MANET must be efficient and resource-saving. One way to reduce routing control traffic is to divide the network into clusters. Clustering of nodes into groups efficiently minimizes flooding and routing traffic overhead. The main issue in cluster based routing is to elect an appropriate cluster head. Because, cluster heads may move often due to high mobility that leads to frequent re-clustering. Most of the existing cluster based routing protocols were based on single cluster head election. The elected cluster head consumes more battery power than other nodes as it has the extra responsibility of forwarding packets; it is very difficult to maintain network stability. Therefore, we propose a new double cluster head based routing protocol to improve network stability and to reduce frequent path failures. The performance of the proposed scheme is evaluated with NS2 simulator and shows better performance in terms of the packet delivery ratio, throughput and delay when compared to a distributed weighted Cluster Based Protocol (CBPMD).
