The topic of reducing energy dissipation and prolonging network lifetime in Wireless Sensor Networks (WSNs) has attracted much attention of researchers. A primary obstacle is the hot spot issue which means data forwarding load for nodes near sink is too much and they usually die early. In this paper, we propose circle-based data dissemination (CBDD) algorithm which utilizes mobile sink to relieve hot spot phenomenon. We assume sensor nodes are symmetrically deployed in a circle sensor field and sink moves around the circle. The sink sends a query message to a specific node for sensed data, which begins a data gathering process. All the nodes belong to different layers according to the distance to sink and the queried nodes communicate with sink layer by layer. Simulation results prove that our algorithm achieves better balance between energy dissipation and network lifetime compared with conventional approaches with static sink.
