Simulation of Data Transmission during a Disaster through Portable Satellite Phones

为了在灾害发生时建立稳定高效的信息网络，我们对通过卫星电话和互联网进行数据传输的效率进行了调查。方法：我们使用便携式卫星电话、笔记本电脑和便携式电池单元模拟数据传输。我们访问了网络的漂亮服务与预设的严重损害我们的大学网络。发送到IAA（我还活着项目）WIDE服务器的数据系列包括患者的姓名、年龄、性别以及患者的位置和健康状况。约600例患者的数据被描述为CSV文本，并以2800 B的速度通过数据传输发送。P. S.数据还被发送到匹兹堡大学的Web服务器，以公布我们医院的损失严重程度和住院患者的情况。结果：患者数据系列的大小为70，688次叮咬。数据以最小的时间延迟发送到IAA和匹兹堡大学的服务器。这些数据被转送到宇航科学院的在线数据库，供公众查阅。它还显示在匹兹堡大学的网页上，供国内和国际访问。结论：通过卫星电话和互联网传送数据将是灾害期间有用和稳定的信息传送方式，数据将传送到宇航科学院联机数据库和某些网站，供公众查阅。

In order to establish the information network that will be stable and efficient during a disaster, we investigated the efficiency of data transmission through satellite phones and the Internet. Methods : We simulated data transmission using a portable satellite phone, a lap top computer, and a portable battery unit. We accessed the Network of Nifty-Serve with the presetting of severe damages on the network of our University. The data series which were sent to the WIDE Server for IAA (I Am Alive Project) included name, age, sex of the patients and location and wellness of the patients. The data for approximately 600 patients were described as the CSV text and were sent by the data transmission at the speed of 2800 b. p. s. The data were also sent to the web server at University of Pittsburgh to announce the severity of damages in our hospital and the situations of the patients admitted. Results : The size of the patient data series was 70,688 bites. The data was sent to the server of IAA and of University of Pittsburgh with minimum time delay. The data was forwarded to the IAA on-line database for the public access. It was also shown on the web page of University of Pittsburgh for the national and international access. Conclusion : Data transmission through satellite phones and the Internet will be a useful and stable way of information transmission during a disaster and the data will be forwarded to the IAA on-line database and to some web site for the public access.
