Abstract

Applying sensor network to emergency lifesaving systems called Triage to decide priority of transportation in disasters is an active area of research. It is necessary to keep collecting data by sensors fixed in injured people. Sensors selected as relay nodes consume battery in large quantity and are easy to be out of battery in collecting the data. In addition, sensors secede from the network because injured people are transported sequentially. But sensors transported later are easy to be out of battery because of remaining in the network for a long time. So in this paper, we propose selection of relay nodes adapted to priority of transportation. Our proposal keeps the packet arrival rate and suppresses the battery consumption totally by generating multiple routes by broadcast from the sink. In addition, it suppresses battery consumption of sensors transported later by using priority of transportation. We evaluate our proposal by the simulation and show this effectiveness.

分流网络中适合运输优先级的中继节点选择的检验

将传感器网络应用于紧急救生系统Triage以确定灾害中运输的优先级是一个活跃的研究领域。有必要通过固定在受伤人员身上的传感器不断收集数据。作为中继节点的传感器消耗电池量大，在采集数据过程中容易出现电量不足的情况。此外，由于受伤人员是按顺序运送的，传感器也会从网络中分离出来。但后期运输的传感器由于在网络中停留时间较长，容易出现电量不足的情况。因此，本文提出了与运输优先级相适应的中继节点选择方法。我们的方案通过从sink广播生成多条路由来保持数据包到达率并完全抑制电池消耗。此外，它还利用运输优先权抑制了后期运输传感器的电池消耗。通过仿真验证了该方法的有效性。
