Survey on Energy-Aware Routing and Routing Protocols for Sensor Networks

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.
