This project is motivated by the following challenges that arise due to the growth of services and applications that rely on radio technologies: (i) As spatial density of spectrum usage increases more wireless systems need to coexist on common spectrum bands, (ii) The energy footprint of wireless information technologies grows at a remarkable pace that is exacerbated by the increasing density, and (iii) An increasing fraction of applications require tight delay guarantees that are incompatible with classical random access techniques. The objective of the program is to develop a scalable framework for providing delay guarantees in dense spectrum usage scenarios, while eliminating energy consumption in medium access arbitration. Towards this goal the project studies fundamental properties and implementations of periodic medium access schemes under which conflicting transmissions are separated in time. Inherent properties of periodic spatial systems are studied from both descriptive and prescriptive viewpoints. The scope of the program includes development of decentralized algorithms that are provably robust to propagation delays, hidden nodes, and clock drifts.An energy-efficient framework for wireless access will have favorable impact on the footprint of information technologies due to both operational energy consumption and battery manufacturing. Successfully completed program will also facilitate dense usage of spectrum with predictable service quality, and thereby will lead to better utilization of an important public resource. The project has educational components at the graduate and undergraduate levels, and potential impact in upcoming networking standards.

该项目的动机是由于依赖无线电技术的服务和应用的增长而产生的以下挑战：（i）随着频谱使用的空间密度的增加，更多的无线系统需要在公共频谱带上共存，（ii）无线信息技术的能量足迹以显著的速度增长，该速度由于密度的增加而加剧，以及（iii）越来越多的应用需要与经典随机接入技术不兼容的严格延迟保证。该计划的目标是开发一个可扩展的框架，在密集的频谱使用情况下提供延迟保证，同时消除介质访问仲裁中的能耗。 为了实现这一目标，该项目研究的基本属性和实现的周期性介质访问方案下，冲突的传输在时间上分开。从描述性和规定性两个角度研究了周期空间系统的内在性质。该计划的范围包括开发分散式算法，这些算法对传播延迟、隐藏节点和时钟漂移具有可证明的鲁棒性。由于运营能耗和电池制造，无线接入的节能框架将对信息技术的足迹产生有利影响。 成功完成的计划还将促进频谱的密集使用，并提供可预测的服务质量，从而更好地利用重要的公共资源。该项目具有研究生和本科生级别的教育内容，并对即将到来的网络标准产生潜在影响。
