NeTS-WN: Network Architecture and Abstractions for Environment and Traffic Aware System-Level Optimization of Wireless Systems

本项目主要研究在干扰受限条件下运行的无线网络的系统级优化的网络结构和抽象。其核心思想是协调网络传输，使其与交通和环境的特征相一致。研究利用数据挖掘技术生成粗略的流量抽象，捕获时空多样性的交通和环境的显著特征。这些抽象业务负载驱动跨相邻基站的协调传输调度的较慢时间尺度系统级优化，同时允许由单个用户业务和动态干扰的实现驱动的更快的(本地)动态调度。这项研究利用自适应、稳健和随机优化的工具进行分析和算法开发。研究议程的独特之处在于，它开发了实现个人用户动态与从测量和抽象用户群体流量/环境到网络协调等问题的耦合所需的综合观点和基本设计原则。初步结果表明，这种方法有可能大幅降低干扰和平均功耗，同时提高覆盖范围和服务一致性。这项工作可以推动当前和未来的无线技术和标准发生有益的变化。奥斯汀大学的无线网络和通信集团(WNCG)与业界的紧密联系为这项工作产生更广泛的影响提供了具体的机会。此外，该项目包括以教育为基础的举措，包括课程开发、研究生培训和本科生的参与，使他们以综合的方式接触研究和工业。

This project centers on investigating network architectures and abstractions for system-level optimization of wireless networks operating in an interference-limited regime. The central idea is to coordinate network transmissions so they are 'aligned' with the character of the traffic and environment.The research leverages data mining techniques to generate coarse traffic abstractions, capturing the salient characteristics of the spatio-temporally-diverse traffic and environment. These abstract traffic loads drive a slower time-scale system-level optimization of coordinated transmission schedules across neighboring base stations, while allowing faster (local) dynamic scheduling driven by the realizations of individual user traffic and dynamic interference. The research draws on tools from adaptive, robust and stochastic optimization for both analysis and algorithmic development. The research agenda is unique in that it develops an integrated view and foundational design principles needed to realize the coupling of individual user dynamics with problems ranging from measuring and abstracting user population traffic/environment to network coordination. Preliminary results suggest that this approach has the potential to enable substantial reductions in interference and average power usage, while increasing coverage and service uniformity.This work can drive beneficial changes in current and future wireless technologies and standards. U.T. Austin's Wireless Networking and Communications Group's (WNCG) strong ties with industry provide concrete opportunities for this work to have a broader impact. In addition, this project includes education-based initiatives, including curriculum development, training of graduate students, and involvement of undergraduates, exposing them to research and industry in an integrated manner.
