Current research in wireless networking technologies introduce several energy efficient routing protocols in sensor networks. These protocols aim to prolong the overall lifetime of network by reducing the energy consumption of nodes. Transfer of gathering information from the sensing field to the base station must be done in proficiently to sustain the network longer. Clustering is one of the process to achieve this goal. Cluster based hierarchical routing protocol have proven to be effective in management of network topology, minimize the energy level, data aggregation and so on. In this paper, we intend to discuss some of the major hierarchical routing protocols adhering towards sensor networks. Moreover, we examine and compare several aspects and characteristics of few explored hierarchical cluster-based protocols, and its operations in wireless sensor networks (WSN). This paper also presents a discussion on the future research topics and the challenges of hierarchical clustering in WSNs.
