Sensor is a small device for communication and computation by capturing information regarding temperature, humidity, pressure etc… Wireless sensor network lies of single sensor or nodes that corporate to execute certain task and these nodes use wireless communication to enable their coactions. These sensor nodes have a limited transmission range; processing; storage capacity and energy resources like computation with limited efficiency. Due to these constraints, network lifetime plays vital role in the functionality of any wireless sensor network. To increase a network lifetime of network, it is required to analyze routing protocols because the transmission of information from one node to another, consumes maximum resources. There are main seven categories: Location-based Protocols, Data-centric Protocols, Hierarchical Protocols, Mobility-based Protocols, Multipath-based Protocols, Heterogeneity-based Protocols, QoS-based protocols. Among all these routing protocols, hierarchical routing protocols used in most of the recent WSNs. In this paper we study the recent hierarchical routing protocol for WSNs. The goal of this study is to analyze and compare the performance of different hierarchical routing protocols for wireless sensor networks. The study will help researchers and developers to use different routing algorithm in different scenarios.
