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...
Aid supporting systems for emergency cases to collect patientspsila medical data such as their conditions, blood pressure and so on real-time are developing recently. Part of them form sensor network and collect patientspsila medical data. Among data,there are important data needed to be sent immediately. However, sending the data with unicast has problem about loss at midstream of the path. On the...
In disaster areas, a high demand of call requests initiated by people in such areas is sent to mobile networks because they might need to use emergency services or inform their families, friends about their current situation. In this paper, we introduce an emergency multi-system access (EMSA) which utilizes WCDMA networks and exploits a mechanism of selecting proper base station (SPBS). In the emergency...
The so-called emergency communications at the time of catastrophic disaster etc. is considered to use ad hoc network effectively. Therefore, it is important to configure emergency communications networks that offer required sufficient QoS in disaster conditions using ad hoc networks. We arrange information and communication required after a disaster from the viewpoint of time elapsed since the disaster...
