A novel dynamic base station positioning method for wireless sensor networks

The type of communication between the nodes in wireless sensor networks (wsn) as well as the placement of the base stations has an important role on obtaining energy efficiency, prolonging the network lifetime and dependently increasing the number of forwarded packages in network. this study suggests a new dynamic placement algorithm for base stations, which considers both the location and the energy level of the nodes with minimum movements. the performance of this algorithm is investigated comprehensively on different kinds of clustering algorithms such as k- means and k-medoid as well as heed by using various wsn parameters. the simulations are conducted using omnet++ simulation environment and the results show that the proposed dynamic base station positioning algorithm yields better performance than stable base station positioning, which reaches up to 119.2% and 262.6% on network lifetime and the number of arrived packages to the base station, respectively.
