CSR-DMSS,TM: Distributed Computing With an Ad-Hoc Network

一个集成的低功率无线电收发器与一个后端处理器结合在一个单一的网络节点上，使传统传感器节点平台无法实现的应用成为可能。如果这样的节点可以在CMOS工艺中批量生产，而不需要昂贵的外部晶体，这样由一组同质节点组成的网络对网络变化或任何节点故障都具有鲁棒性，那么可以由这些节点的集合形成可靠的自组织网络，具有类似于分布式机器的群体智能。该项目侧重于开发和利用分布式计算机器，该机器由集成的单芯片微系统网络组成，该网络将通信和计算功能结合在一起，总功耗预算在50ìW以下。低功耗性能对长寿命至关重要，通过收发器的占空比和通过脉冲耦合振荡器（PCOs）的自然现象建立全局时钟以及使用简单的事件驱动计算来实现。虽然每个节点的计算能力有限，但这种网络的能力将来自于执行分布式计算任务的聚合能力。这个项目探讨了三个问题；从简单节点的网络构建，网络内的通信，以及这样一个受限平台的计算潜力。这项工作的最终目标是开发一个具有计算模型和能够利用该网络的原语的完整网络。S的独特之处。

Abstract for Dr Alyssa ApselAn integrated low power radio transceiver combined with a backend processor in a single networkable node enables applications that are not possible with traditional sensor node platforms. If such a node can be mass produced in a CMOS process without a costly external crystal such that the network formed by a set of homogenous nodes is robust to network changes or any node failing, then reliable ad-hoc networks may be formed from sets of these nodes with group intelligence akin to a distributed machine. This project focuses on the development and exploitation of a distributed computing machine formed out of a network of integrated single chip microsystems that combine both communication and computation functions with a total power budget that is under 50ìW. Low power performance, critical to long lifetimes is achieved through duty cycling of the transceiver and establishment of a global clock via natural phenomenon of pulse coupled oscillators (PCOs) as well as the use of simple event driven computation. Although each node has limited computing capability, the power of such a network will arise from aggregate capabilities to perform distributed computing tasks. This project explores three issues; the construction of the network from simple nodes, communication within the network, and the computing potential for such a constrained platform. The final goal of this work is to develop a complete network with computing models and primitives capable of exploiting the network?s unique features.
