An energy efficient routing technique to improve the performance of wireless sensor network through adaptive tree based sink relocation

Wireless sensor networks can be deployed in normal as well as rough environment for data gathering fashion. Sensor nodes are more easy to failure because of their battery sources are irreplaceable. In Wireless Sensor networks (WSN), the sensors near to the sink will drain out of their energy first, resulting in holes in the WSNs. An important base for energy efficient routing technique in wireless sensor networks is the formation of energy holes near the sink. In this paper we propose Adaptive Tree Based Sink Relocation (ATBR) model. The proposed mechanism uses information related to residual battery energy of sensor nodes to adaptively adjust the routing tree and relocating scheme for the sink.
