The hierarchical clustering is an efficient way to reduce the overall energy consumption within the cluster by performing aggregation and fusion of data. Clusters create hierarchical WSNs, which facilitate efficient utilization of the limited resources of sensor nodes, thereby extend the network lifetime, reduce energy consumption of the system and provide overall system scalability. The proposed work of the present paper is to provide an overview of hierarchical protocols and an overview of the protocol's performance. The study of different clustering routing protocols of WSN and Ad-Hoc are presented and the aim is to give the comparison of different hierarchical routing protocols between WSNs and Ad-Hoc on various parameters.
