Self-adaptive Algorithm SESP based on Energy Assessment of Wireless Sensor Network Node

Abstract

The energy of the nodes of Wireless Sensor Network (WSN) is finite. For the extension of the lifespan of the nodes, we propose a self-adaptive algorithm (SESP) based on energy assessment of WSN nodes with identical hardware model and same parameters. SESP is able to choose the cluster head without sending message to learn the surplus energy of other nodes, thus reducing in-cluster communication and simplifying the calculation of energy assessment, and eventually reducing energy consumption of WSN nodes and extending their lifespan.
