CAREER: An In-Network Collaboration and Coordination Framework for Wireless Sensor Actor Networks

针对无线传感器网络中的网络内处理问题，已经有了许多有效的点解决方案，但对于设计一个能够实现网络内处理协议标准化和集成的网络内协作和协调框架这一根本性的研究问题却鲜有关注。这个项目的目标是设计和实现这样一个框架。该框架引入了一个分散的事务模型，使节点能够一致地、自动地更新其单跳邻居的状态。该框架的一个关键见解是观察到单跳无线广播在促进协作和协调方面具有许多有用的特性。通过利用单跳无线通信的原子性和广播属性，该框架提供了一个简单/干净的抽象，但仍设法保持执行效率。此外，本项目还研究了无线传感器网络中接收端碰撞检测在单跳协同反馈采集中的实际应用。通过解决其简单抽象下的通信和并发执行挑战，该框架将为开发和部署分布式控制应用程序以及WSN网络内处理协议提供平台。因此，该框架将有助于多机器人协同控制应用和wsn -机器人集成的分布式传感。更具体地说，该框架将通过在WSNs中开发分布式多跟踪/多逃避跟踪应用来演示。拟议的职业规划通过跨学科课程、开发和传播系统软件将研究和教育结合起来。

While there have been many efficient point solutions to the in-network processing problems in wireless sensor networks (WSNs), there has been little effort to address the underlying root research problem of devising an in-network collaboration and coordination framework that can achieve standardization and integration of in-network processing protocols. The objective of this project is to design and implement such a framework.This framework introduces a decentralized transactional model that enables a node to update the state of its singlehop neighborhood consistently and atomically. One of the key insights in this framework is to observe that singlehop wireless broadcast has many useful features for facilitating collaboration and coordination. By exploiting the atomicity and broadcast properties of singlehop wireless communication, the framework provides a simple/clean abstraction and yet manages to retain the efficiency of execution.Moreover, this project also investigates the practical uses of receiver-side collision detection in singlehop collaborative feedback collection in WSNs.By addressing the communication and concurrent execution challenges under the hood of its simple abstractions, the framework will provide a platform for developing and deploying distributed control applications as well as WSN in-network processing protocols. As such, this framework will be useful for multi-robot cooperative control applications and WSN-robotics integration for distributed sensing.More specifically, the framework will be demonstrated by developing a distributed multiple-pursuer/multiple-evader tracking application in WSNs. The proposed career plan integrates research and education through interdisciplinary coursework development and dissemination of systems software.
