  4. Abstract:
  5. Previous studies on wireless sensor networks indicate one of the most important research topics is to consider both significance of the reduction in sensor nodes energy consumption and improving network lifetime. Regarding results of some researchers using sinks, mobility has a substantial impact on the performance of sensor networks concerning reducing total energy consumption, increasing the number of active nodes and solving the energy-hole problem. In this study, we consider hexagons beehives feature where sensor nodes are distributed across a hexagon randomly. This hexagonal is divided into equal clusters based on the radius of hexagonal. Also, the need for cluster heads to be close to their centre of clusters in the previous similar model is solved by adding mobility to the sinks, providing a pre-determined path for mobile sinks and covering each cluster by sinks from two different directions. Therefore, the proposed model simulation results show the increase in the average of residual energy between sensor nodes, reducing total energy consumption, increasing the number of active nodes and ultimately improving the lifetime of wireless sensor networks related to previous models. © 2019, Springer Science+Business Media, LLC, part of Springer Nature
