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.

Alyssa ApselAn集成的低功耗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CMOS工艺中大规模生产而不需要昂贵的外部晶体，使得由一组同质节点形成的网络对于网络变化或任何节点故障是鲁棒的，则可以从具有类似于分布式机器的组智能的这些节点的集合形成可靠的自组织网络。该项目的重点是开发和利用一个分布式计算机形成了一个网络的集成单芯片微系统，联合收割机结合通信和计算功能的总功率预算是在50毫瓦。低功耗性能，长寿命的关键是通过收发器的占空比和建立一个全局时钟通过脉冲耦合振荡器（PCO）的自然现象，以及使用简单的事件驱动计算。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。该项目探讨了三个问题：从简单节点构建网络，网络内的通信，以及这种受限平台的计算潜力。这项工作的最终目标是开发一个完整的网络计算模型和原语能够利用网络？的独特功能。
