PDF Based Node Localization In Clustered Wireless Sensor Networks

Today increasing the energy consumption efficiency of nodes in wireless sensor networks (WSN) is one of the main problems of the network. The issue of energy saving in wireless sensor networks requires great attention. One of the main ways to save energy is the rational placement of sensor nodes in the network area, which in turn allows to balance the flow of energy, throughout the network and prevent the appearance of “energy holes”. In this paper, the viability of the network is analyzed. The parameter density of the sensor node that affects network viability has been identified. In order to meet the energy balancing requirement, a mathematical model of node placement based on the probability density function (PDF) developed.
