In wireless sensor networks (WSNs), the assistance of exploiting the sink mobility to extend network lifetime have been well identified. This paper delivers an energy-efficient routing system stationed on the cluster-based approach considering obstacles for the mobile sink in WSNs. Based on cluster method, the node is elected as a cluster head which collects data from their respective cluster members and forwards the data to the mobile sink. In this paper, the mobile sink initiates the data-gather route periodically from the beginning site, then directly gets data from these cluster heads in a single-hop range, and lastly backs to the initial site. However, having obstacles in WSN’s the complexity of the scheduling problem increases the traditional algorithms are difficult to resolve.
