面向城市数据分发的无线网络资源高效路由及传输调度研究

Data transmission and dissemination in urban area is a key technology for realizing smart city and urban crowd-sensing based systems. In this project, we study the key problems in data transmission and dissemination in urban networks and accordingly propose some novel routing and scheduling mechanisms for addressing these problems, by taking into account the characteristics of urban networks such as the uneven distribution of resources and data flows, significant link diversity, node heterogeneity, and etc. The new proposed mechanisms include multi-scale network-division based resource-aware routing selection and transmission scheduling mechanism, link-diversity based resource-balanced routing selection and transmission scheduling mechanism, and node-heterogeneity based efficient backpressure routing and scheduling mechanism. The objectives of this project are to significantly improve the network throughput, transmission reliability, network resource utilization efficiency, and load balance of urban wireless networks.
