中文摘要: 随着接入Internet的物联网设备数目的增多,组合物联网中已有资源来构建用户应用将成为未来物联网应用开发的主流模式。然而,应用需求的个性化增加了物联网应用构建时的难度与成本,网络的强异构性与高动态性提高了保持应用运行时鲁棒性的难度,应用数目的海量性使得资源受限设备需要支持较大的并发任务量。本项目提出一种应用与执行分离的物联网水平化应用构建方法,使得同一个应用程序可运行在多种不同的网络环境中,提升应用程序的适用性,避免由于应用个性化导致的应用开发成本过高的问题;提出一种运行时资源主动实例化机制,通过资源模糊选择降低网络异构性的影响,同时基于网络节点的失效概率主动完成资源选择与映射,保证应用程序执行的鲁棒性;提出一种利用物联网应用之间的相似性优化冗余开销的机制,提高资源受限设备的并发任务执行效率。本项目探索未来海量用户共同使用物联网基础设施时将面临的关键问题及其解决方案,具有重要的理论价值。

英文摘要: With the increase of the number of existing network resources in Internet of Things, building user application by compositing existing equipment will become the mainstream mode of the IoT application development. However, the application of the personalized demand increases the difficulty and cost of constructing IoT application. Strong heterogeneity and high dynamic of the network increase the difficulty to keep the application running robustness. Massive application number makes the resource constrained devices need to support a large amount of concurrent tasks. This project aims to put forward the method of constructing a IoT application, making the same application can run in a variety of different network environment, promoting the applicability of the application, avoiding the high cost of developing applications because of personalized requirement; This project also aims to propose a run-time resource active instantiation mechanism, through fuzzy choice to reduce the effects of heterogeneous networks, and reduce network node failure probability of the initiative to complete the selection and mapping based on resources, ensuring the robustness of application execution; This project also aims to put forward a matter similarity redundancy optimization overhead mechanism between the networking applications, improving the execution efficiency of concurrent tasks in resource constrained devices. The project is aim to explore the key issues of future mass users to share the network infrastructure and its solutions, which has important theory value and practical significance.
