物联网搜索技术综述 总被引:1,自引:0,他引:1
随着物联网的普及和发展,物联网搜索是摆在学术界和工业界面前迫切需要解决的问题,物联网搜索因此成为当前的一个研究热点。面对越来越多的传感器以及它们所产生的数据,只有结合智能的物联网搜索,才能体现这些数据的生命力。与传统的Baidu、Google、Bing、Yahoo等搜索引擎不同,物联网搜索从搜索对象、物理网数据的特点(大规模的、实时变化的、高度动态的、异构的、复杂的安全环境等)到物联网搜索的架构均与传统互联网不同,这导致了物联网搜所面临的挑战将更大。由此,阐述了物联网搜索的概念、特点、相关技术,对现有的典型系统和算法进行了比较性总结,分析了目前研究中存在的问题和挑战,并展望了其未来的发展方向。 相似文献

Internet of Things (IoT) and its relevant technologies have been attracting the attention of researchers from academia, industry, and government in recent years. However, since the requirements of the IoT are quite different from what the Internet today can offer, several innovative techniques have been gradually developed and incorporated into IoT, which is referred to as the Future Internet of Things (FIoT). Among them, how to extract “data” and transfer them into “knowledge” from sensing layer to application layer has become a vital issue. This paper begins with an overview of IoT and FIoT, followed by discussions on how to apply data mining and computational intelligence to FIoT. An intelligent data management framework inspired by swarm optimization will then given. Finally, open issues and future trends of this field will be addressed. 相似文献

The role of investors in the growth of startups has been continuously studied. Our paper complements this stream of research by adding a new role of the investor in the Internet of Things (IoT) field, as a channel of knowledge sharing among startups. The relationship between “Internet of Things” startups located in the US and its investors leads to technology convergence as a result of knowledge sharing from investors. Using network analysis and a co-occurrence method, we find that investors in the IoT field play an intermediate role connecting startups by forming an ideal topology for knowledge sharing among them in the IoT industry. IoT startups having investors and more connections to other startups show greater technology convergence. Based on the above findings, this study argues that technology convergence occurs in the venture network as a result of investors playing the role of a channel of knowledge flow. 相似文献

随着物联网(IoT)规模的不断发展,其业务需求呈现出多样化、全球化的趋势。针对地面物联网无法覆盖全球的缺点,卫星物联网尤其是低轨卫星星座(LEOSC)物联网可以有效地为地面物联网提供覆盖性能上的补充和延伸。由于低轨卫星星座物联网系统广覆盖、高动态的特点,其业务量统计特性需要考虑到环境因素造成的影响,这导致其业务量分布与地面物联网存在显著差异。从合理高效利用星上有限资源角度出发,该文研究基于低轨卫星星座的全球物联网业务模型。结合多样化的业务特点以及卫星通信系统特性,采用统计建模理论,得出了全球物联网业务模型框架。并且初步提出了一种基于最高优先级的接入策略,以供设备节点实时选择接入的卫星。仿真结果表明:泊松过程可以用于近似模拟低轨卫星物联网中大量存在的异步流量的叠加过程;由于低轨卫星具有高动态性,其业务源高速变化,导致了卫星业务忙闲不均,峰均比(PAR)较高。 相似文献
