Researches of sensor networks collecting patients' data with computerized triage tags, called Triage network, are developed. In Triage networks, network topology changes frequently. Because some sensors have mobility and each sensor participates in Triage networks and secedes from them with frequency. As a result, route to a sink fails and power consumption increases by increase of the number of re-searching routes and the number of packets transmissions and receptions. In this paper, we propose an energy efficient data collection method by two types routes selection in Triage networks. In our method, to consider mobility and topology changes, two types routes, Electric power efficient route and Stable route, are used depending on mobility existence. Electric power efficient route is used where sensors with short participating time work as relay sensors positively. Stable route is used where sensors which don't secede easily and links don't fail easily work as relay sensors positively. We evaluate our proposed method using computer simulations and show its effectiveness.
