【摘要】 分析使用普适无线网构建地震实时数据远程传输共享应用平台的不足,现有的STEIM1和STEIM2压缩算法无法满足波动增大和频率增高的原始数据压缩。针对现有压缩算法的不足,提出了新的三向数据分布区间压缩和重传算法,减少普适无线网的链路负载和增加应用层控制,降低延时抖动,大幅提升平台运行率,使其达到了实用化效果。更多还原

【Abstract】 Shortages of using ubiquitous wireless networks to build earthquake real-time data remote transferring and sharing applications platform are analyzed,and it isn’t suitable to compress earthquake real-time data when it uses STEIM1 and STEIM2 compression algo-rithms for huge undulation and high frequency data.One brand-new compression and retransfer algorithm named distributing extent of three direction data(DETDD) is proposed,it’s suitable to reduce traffic flow and enhance control of application layer,decrease to delay and delayjitter,clearly advance to the platform’s run-rate,so make the platform become effective availability.更多还原
