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

摘要对于Alyssa Apsel博士来说，集成的低功率无线电收发器与单个可联网节点中的后端处理器相结合，可以实现传统传感器节点平台无法实现的应用。如果这样的节点可以在没有昂贵的外部晶体的情况下在CMOS工艺中大量生产，从而由一组同质节点形成的网络对网络变化或任何节点故障都是健壮的，则可以由具有类似于分布式机器的组智能的这些节点的集合来形成可靠的自组织网络。本项目致力于开发和开发由集成的单片微系统网络组成的分布式计算机，该网络将通信和计算功能结合在一起，总功率预算低于50？W。低功率性能是通过收发器的占空比和通过脉冲耦合振荡器(PCO)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的，低功率性能对长寿命至关重要。虽然每个节点的计算能力有限，但这种网络的能力将来自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：从简单的节点构建网络，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原语的完整网络，这些计算模型和原语能够利用网络-S的独特功能。

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.
