无线传感器网络通过提供物理世界和虚拟世界之间的高分辨率接口，有望在信息技术领域掀起一场革命。本研究项目旨在为分析和设计这些系统中的数据收集协议建立数学基础。该项目开发了传感器网络应用、环境条件和协议参数的数学模型，以便根据能源效率和响应延迟等关键指标量化和绑定协议的性能。它补充了研究界通过模拟和实验研究设计和评估这些协议的其他正在进行的努力。本项目开发的协议数学模型将为无线传感器网络设计人员提供实用指南和见解，以选择和优化不同应用的协议，并使其自适应。基本性能界限将揭示是否有改进的空间，在某些情况下甚至建议新的高效协议设计。该研究正在与学术界和工业界的无线传感器网络系统和应用研究人员密切合作进行，以确保分析得到现实世界系统设计的信息并对其产生重大影响。这种无线传感器网络被设想用于从环境、工业和结构监测到安全应用的广泛领域。该研究与一个教育项目紧密结合，包括将研究活动整合到南加州大学的本科研究生网络课程中，并向洛杉矶的公立高中学生推广。

Wireless sensor networks promise a revolution in information technology, by providing a high-resolution interface between the physical and virtual worlds. This research project aims to create a mathematical foundation for analyzing and designing data gathering protocols in these systems.This project develops mathematical models of sensor network applications, environmental conditions, and protocol parameters, in order to quantify and bound the performance of protocols with respect to key metrics such as energy efficiency and response latency. It complements other ongoing efforts in the research community to design and evaluate these protocols via simulations and experimental studies. The mathematical models of protocols developed in this project will provide wireless sensor network designers with practical guidelines and insights on selecting and optimizing protocols for different applications, and making them adaptive. Fundamental performance bounds will reveal whether there is room for improvement, and in some cases even suggest new efficient protocol designs.The research is being carried out in close collaboration with wireless sensor network systems and applications researchers in academia and industry, to ensure that the analysis is informed by and has a significant impact on the design of real-world systems. Such wireless sensor networks are envisioned to be used in domains ranging widely from environmental, industrial and structural monitoring to security applications.The research is tightly coupled with an educational program that includes integration of the research activities into the undergraduate graduate networks curriculum at the University of Southern California, as well as outreach to public high school students in Los Angeles.
