中文摘要： 物联网技术的发展与成功应用，极大的推动了各个领域信息化的进程。由于无线传感器网络、无线Wi-Fi网络、移动通信网络3G/4G/LTE及无线Mesh网络等异构网络单元融入互联网，使物联网的规模进一步增大，海量数据的产生也给物联网带来了巨大的负载。导致大量的事件产生排队现象，使网络产生拥塞并漫延，系统应急响应能力急剧下降。因此以排队网络为基础，研究物联网中改善服务质量(QoS)的关键因素，对提高物联网中的应急响应速度具有重要的意义。本项目针对物联网中大批量数据汇聚要求，研究高性能嵌入式多核汇聚节点调度策略，分析任务排队机制，使多核达到负载均衡。在大规模物联网感知节点中，利用复杂网络建模方法解决高速命令查询与快速传递，避免拥塞漫延。针对异构网络单元中的基本载体与互联网中的排队事件，利用带优先级的排队网络解决优先级动态分配问题；并对不同类网络中的事件排队队长，时延和最佳服务性能之间的关系进行研究。

英文摘要： The development and successful applications of the Internet of Things (IoT) greatly promote information progress of the various fields. As the Internet integrates many heterogeneous networks, such as wireless sensor networks (WSNs), wireless network (Wi-Fi), mobile comunication networks (3G/4G/LTE) and wireless mesh networks(WMNs), the scale of IoT further increases, which makes heavy load for transmission of huge amounts of data. Therefore, many events need to stay in the queue and wait to be processed. Also the heterogeneous networks are blocked and the system's response performance to emergency situations is reduced a lot. Researches based on queuing networks play important roles in improving IoT's Quality of Service (QoS) and ability to response emergencies. In order to adapt requirements of large amount data aggregation in IoT, this project focuses on the scheduling strategy of high performance embedded multi-core sink node, and analyze the queuing strategy to make the load balanced of each core. As for the sensor nodes in the IoT, in order to avoid congestion spreading, we use modeling approach in complex network to process high-speed queries and rapid transmissions. For basic carriers in heterogeneous network and queuing events in the Internet, we use queuing network with priority to allocate priority dy
