Abstract

The catastrophic earthquake and Tsunami of Tohoku Japan in 2011, caused colossal damages to the ground infrastructures that resulted in the lost of means to acquire and to convey information between rescues and victims of disaster. This unfortunate situation of helplessness prompted us to propose in this paper a reliable means to recover a function of telecom infrastructure immediately by use of portable satellite phone with narrow band. The proposed system consists of sharing Internet access through satellite phone among multiple users and protocol conversion to improve the degraded performance caused by long-latency over satellite communication. The protocol conversion from application protocol like HTTP (Hypertext Transfer Protocol) over TCP (Transmission Control Protocol) to batch-oriented reliable protocol with forward error collection is presented. Through the implementation, we shows that the satellite communication is stabilized even in narrow band and it can be shared among many disaster victims.

集成无线认证系统:自然灾害后多个组织共享卫星通信
2011年日本东北地区的灾难性地震和海啸对地面基础设施造成了巨大的破坏,导致救援人员和灾难受害者之间失去了获取和传递信息的手段。这种无奈的不幸情况促使我们在本文中提出了一种可靠的方法,利用窄带便携式卫星电话立即恢复电信基础设施的功能。该系统由多个用户通过卫星电话共享互联网接入和协议转换组成,以改善卫星通信长时延导致的性能下降。提出了从HTTP(超文本传输协议)等基于TCP(传输控制协议)的应用协议到具有前向错误收集功能的面向批处理的可靠协议的转换。通过实际应用表明,卫星通信在窄带条件下是稳定的,可以在多个受灾地区共享。
