Abstract: Sensor nodes in wireless sensor networks are wirelessly configured, so they are free to install, but there is a problem with limited energy. Since these nodes are no longer usable when they are exhausted, they must use energy efficiently to maximise the network lifetime span. A variety of protocols have been proposed for this, and the cluster-based protocol, the LEACH Protocol, is typical. LEACH Protocol has improved the problem of having the same node elected as the cluster head multiple times through a critical expression, but because it is a probability formula, the cluster can be configured inefficiently. In this paper, we are going to improve the network lifetime by replacing the cluster head with a node in an appropriate position after the cluster is constructed.

Keywords: clustering; cluster head; formation; network; sensor; wireless sensor network; WSN.
