基于无人机的灾害传感与决策系统实现

现代社会,面对高危或人类无法到达的区域,无人机由于体积小和机动灵活,通过其携带设备进行信息传感采集、视频现场捕捉,能安全、有效的获取现场灾情情况信息。利用采集到的现场信息与GIS相关服务,使采集信息可视化,同时进行快速分析与预测。本文设计并实现基于无人机突发灾害监控与决策系统。实践表明,该系统能够实时获取突发灾害现场信息,实现灾害预测分析,为突发灾害应急工作提供有效辅助手段。     

Effective multicasting algorithm for dynamic membership with delay constraint

INTRODUCTION Some new emerging applications involve in- formation transmission in a network. Different from traditional single-cast applications, these new arising applications are called multicast as they contain a single sender and multiple receivers. In general, it is needed to construct a multicast routing tree to deliver information along the tree branches. Because links in the tree are shared by paths to different receivers, just one information copy is needed in the middle node. Th…
