How to use Cluster based Routing Protocol in NS2

Description

In large scale network, data transmission source to destination involves many intermediate routers. If the selected router is not having sufficient capability such its residual energy, it will become dead node after certain network operational period. Hence group of nodes together forms a cluster and elects a clusterhead among them. Routing is done from source to destination through the clusterhead which is having capability when compared to other nodes in the network.
