Tiny, embedded computers will collect real-time data on our homes, our cities, and our planet. Collecting and processing rich streams of sensor data will transform public health, medicine, natural resource management, science, engineering, and disaster response. But today, despite years of research and engineering, these sensor networks often fail to meet their performance goals. Data yields are low; networks last weeks, rather than months; long downtimes are common.Professor Levis proposes a long-term agenda of research and education to improve the robustness, manageability, and scalability of low-power wireless sensing systems. The dominant design principle behind this agenda is network visibility. Described colloquially, visibility measures a user?s ability to identify the cause of a network event, such as a packet drop. We propose to research how to make networks more visible.The research agenda is grounded in the exploration, development, and evaluation of the Mote Network(MNet) architecture, an open-source protocol suite and toolkit for sensor network application development and deployment. The protocol suite will include existing dominant protocols redesigned for improved visibility as well as novel protocols whose designs maximizes visibility. Our principal goal is to make long-lived sensornets significantly simpler to deploy and maintain. Our second goal is to apply our lessons learned to wireless meshes more generally.

微型嵌入式计算机将收集我们的家庭、城市和地球的实时数据。收集和处理丰富的传感器数据流将改变公共卫生、医学、自然资源管理、科学、工程和灾害响应。但是今天，尽管经过多年的研究和工程，这些传感器网络往往无法达到其性能目标。数据产量很低；社交网络可以维持几周，而不是几个月；长时间停机是很常见的。Levis教授提出了一个长期的研究和教育议程，以提高低功耗无线传感系统的稳健性、可管理性和可扩展性。这个议程背后的主要设计原则是网络可见性。通俗地说，可见性衡量用户？识别网络事件（如丢包）原因的能力。我们建议研究如何使网络更加可见。该研究议程基于对Mote网络（MNet）架构的探索、开发和评估，这是一种用于传感器网络应用开发和部署的开源协议套件和工具包。协议套件将包括重新设计的现有的主流协议，以提高可见性，以及设计最大化可见性的新协议。我们的主要目标是使长寿命传感器的部署和维护变得更加简单。我们的第二个目标是将我们学到的经验更广泛地应用于无线网格。
