Variant Path Multiplicity Routing Algorithm Adapted to Importance of Data

Triage is a emergency life-saving process to prioritize patients based on severity of their condition in disasters. Triage has been introduced to medical treatment scenes in recent years. In Triage, patients are classified into 4 groups according to their priority based on their condition. Researches of emergency life-saving systems to monitor and collect patients´ location and changes of their condition are developed. In collecting patients´ data in a sensor network, it is necessary to concern importance of patients´ data according to patients´ priority and improve robustness of data transmission. In this paper, we propose VPMR (Varient Path Multiplicity Routing Algorithm Adapted to Packet Priority). VPMR improves robustness of data transmission by each sender node´s controlling degree of path diversity using importance of data and other patients´ condition. When data is transmitted, each node judges importance of data in Triage network, it selects one path or multiple paths, and it transmits the data. As a result, high priority data can be collected and robustness of data transmission improves. We evaluate our proposal through computer simulations and show its effectiveness.
