Zusammenfassung: | Wireless Sensor Networks (WSNs) consist of small nodes with sensing, computation and wireless communications capabilities. Evolution in wireless sensor network has broadened its pervasive and ubiquitous applications in numerous fields. These applications often require accurate information collecting as well as uninterrupted, prolonged active service. Routing protocols have significant impact on the overall energy consumption of sensor networks. Suitable Energy-efficient routing algorithms are required to the inherent characteristics of these types of networks are needed. Due to resource limitations in wireless sensor networks, prolonging the network lifetime has been of a great interest. Most of the energy of sensor nodes is utilized for transmission of data to the base station. Thus, it makes them to deplete their energy much faster. In this paper, Centrality based Cluster approach is used along with a movable base station to reduce the energy consumption of cluster heads. According to the simulation results, the proposed scheme has proved its efficiency in the network lifetime, residual energy of network. The proposed scheme also shows improvement in performance of WSN compared to other routing scheme. |
