Abstract

Researches of sensor networks collecting patients' data with computerized triage tags, called Triage Network, are attracting attention. The listening power used in triage tags is the major factor of lots of energy consumption, and consumption of energy increases when sensor nodes always communicate with other nodes in active state. Hence, we suppose that sensor nodes are put to sleep periodically to avoid running out of battery. However, some nodes have mobility and nodes secede from the network according to patients conditions in Triage Network. The paths are failed and it is needed to reconstruct paths when these forwarding nodes move or secede from network. Therefore, data arrival ratio decreases and consumption of battery increases due to reconstruction of other paths. In this paper, we propose a data collection method using two types of forwarding nodes, Stable Nodes and Energy Efficient Nodes. This method uses two types of forwarding nodes according to priority of data and avoids loss of high priority data, improves the data arrival ratio and saves the energy consumption. We evaluate the proposed method and show its effectiveness using computer simulations.
