Undergoing revolution in Wireless Sensor Networks, which is made up of batterypowered
nodes empowered with a multitude of sensing modalities, promises to have a significant
impact throughout society. Significant improvement and advancement in processor design,
computing in battery technology still lag behind, making energy resource the major bottleneck in
Wireless Sensor Network. Limited energy nodes are not taken into account in the traditional
routing protocols, which has significant impact on the overall energy dissipation. There are
protocols like table driven, on-demand for such network which follows direct transmission,
minimum-transmission-energy, multi-hop routing, or static clustering. Optimal routing tries to
maximize the duration over which the sensing task can be performed. There are various routing
methods like multi-path routing, query 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 available routing protocol based on energy sense, and various routing
methods proposed by researchers for even energy distribution for Wireless Sensor Network.
