In sensor network environments, sensor nodes have limited power because of their resource constraints. Therefore it is important to efficiently use their power in sensor networks. Power consumption of sensor node is closely related to its communication operation. So, we need to reduce the communication operation in order to minimize the power consumption. And sensor networks are inherently unreliable because radio transmission can easily fail, nodes can move, and so on. In this paper, we propose a reliable data aggregation protocol in order to overcome these problems. This protocol performs the routing and the query insertion process at the same time to minimize the packet loss caused by network changes. Also, this protocol removes the communication operations caused by the periodic routing without query.
