摘要：Field of wireless sensor network is among one of the most emerging and fast growing fields in today’s scientific world. WSN is collaborated from a large number of low cost and minute homogenous sensor nodes connected by a wireless network. These sensor nodes are spread out in sensor field located far from the users. Increasing lifetime of WSN is one among the most critical issues. Sensor nodes are constrained in values of energy, memory and processing capacity. So to overcome such problems, a number of protocols have been proposed for the purpose of data routing in sensor network. Such protocols can be classified into three main groups: data centric, location based and hierarchical. In this paper, we present a brief survey of “Hierarchical Protocols” in which nodes are clustered in various forms to perform data aggregation and multi hop communication. By carrying out the above process, the number of transmitted messages to the base station are reduced, which will be a boon to system scalability and energy efficiency. This paper on the whole focuses on the energy efficient hierarchical cluster based available routing for WSN.
