NeTS-NR: Creating a Wirelss Sensor Net Architecture

摘要：无线传感器网络(WSNs)将通过加速科学研究、提高生产力和增强安全性来造福社会。特定科学挑战的候选解决方案，从设备设计到分布式算法，存在各种假定的要求、约束和组件之间的关系。然而，对于传感器网络的整体架构还没有达成共识。部署只需很小的垂直部分即可实现运营网络。这个项目的目标是制定和评估一个全面的无线传感器网络系统架构，包括一般设计原则、广泛的功能分解和各个部分相互配合的详细接口。该办法认识到，这一架构的“窄腰”--在互联网架构中扮演IP的角色--是一种尽力的单跳广播。阐明基本抽象的主要方法是迭代循环(候选收集、设计、集成、评估)，并将结果提交给社区进行分析，以在一般性和性能之间建立正确的折衷。此流程将阐明一致的编程接口，包括收集、聚合、分发、邻居、以数据为中心的存储以及多个链路层上的基于属性的路由。该架构将在效率、协调、电力、管理和安全等交叉方面进行测试。它应该支持异构性，并允许在一致的框架内进行特定于应用程序的优化。为无线传感器网络创建一个成功的架构将减少开发工作，实现更大的协同和互操作性，实现更快速的创新，并极大地拓宽从国家安全到科学研究和生态系统管理的应用领域。

Abstract: Wireless Sensor Networks (WSNs) will benefit society by accelerating scientific research, increasing productivity, and enhancing security. Candidate solutions to particular scientific challenges, ranging from device design to distributed algorithms, exist with various assumed requirements, constraints, and relationships between the components. However, there is no consensus on an overall sensor network architecture. Deployments take a narrow vertical slice to achieve a operational network. The objective of this project is to formulate and evaluate a comprehensive WSN systems architecture, encompassing general design principles, broad functional decompositions, and detailed interfaces by which pieces fit together. The approach recognizes that the ``narrow waist" of this architecture -- playing the role of IP in the Internet architecture -- is a best-effort single-hop broadcast. The primary method for articulating the essential abstractions is iterative cycles of (candidate collection, design, integration, evaluation) with the outcome presented to the community for analysis to establish the right compromises between generality and performance. This process will articulate consistent programming interfaces that encompass collection, aggregation, dissemination, neighborhoods, data centric storage, and attribute-based routing over multiple link layers. The architecture will be tested on cross-cutting aspects of efficiency, coordination, power, management, and security. It should embrace heterogeneity and allow for application-specific optimization within a consistent framework. Creating a successful architecture for WSNs will reduce development effort, allow greater synergy and interoperability, enable more rapid innovation, and greatly broaden the sphere of applications from national security to scientific research and ecosystem management.
