A query processor to control and manage the reliability and efficiency of sensor nodes in a wireless sensor network was designed and implemented. Sensor node with the proposed query process combines environmental and medical sensors in order to monitor both pollution states of the surrounding indoor room of the patient and the patient's health status continuously. This feature allows a comprehensive understanding of the patient's condition in indoor environment. Another feature of our system provides an anytime, anyway, anyservice and effective way for connecting our indoor environmental and medical sensor nodes of sensor network to outside world. This paper presents a tiny aggregation service and reliable query protocol for aggregation in sensor node. The tiny aggregation allows users to make simple and declarative queries with reliability and efficiency in low-power wireless sensor node. The reliable query protocol in indoor environment and medical sensor node is very effective because of power saving and reliable data transmission between sensor nodes.
