ABSTRACT
Recent technological advances in communications and computation have enabled the development of low-cost, low-power,
small in size, and multifunctional sensor nodes in a wireless sensor network. Since the radio transmission and reception
consumes a lot of energy, one of the important issues in wireless sensor network is the inherent limited battery power within
network sensor nodes. Therefore, battery power is crucial parameter in the algorithm design to increase lifespan of nodes in
the network. In addition to maximizing the lifespan of sensor nodes, it is preferable to distribute the energy dissipated
throughout the wireless sensor network in order to maximize overall network performance. Much research has been done in
recent years, investigating different aspects like, low power protocols, network establishments, routing protocol, and
coverage problems of wireless sensor networks. There are various routing protocols like location-aided, multi-path, datacentric, mobility-based, QoS based, heterogeneity-based, hierarchical routing, hybrid routing, etc., in which optimal routing
can be achieved in the context of energy. In this paper, the focus is mainly driven over the survey of the energy-efficient
hierarchical cluster-based available routings for Wireless Sensor Network.
