On interchangeable sensor networks and its dynamic reconfigurable application development

本文主要研究具有节点互换性的传感器网络及其应用开发技术。提出了互换性传感器网络应用开发的总体方案,指出节点在传输协议和应用层协议均需取得一致。提出一套轻量级应用层协议AgileSN,支持节点的自动发现,支持数据的动态解析;详细描述了AgileSN的网络与节点模型,及其工作过程。在节点互换性的基础上,借鉴WEB系统的工作模式,提出一套适用于传感器网络的动态可重构应用开发平台IsVIP,采用组件化的体系结构,能够在运行时动态创建和重构应用系统;支持多数据流并行与流水线并行。介绍了IsVIP的模型,研究了其运行性能,并进行了性能测试,结果显示流水线能够大幅度的提高吞吐率。文中最后给出一个实例,利用AgileSN仿真节点和IsVIP快速灵活的搭建PC性能参数监测系统。

This paper primarily studies sensor network interchangeability and its application development. We propose an architecture framework to realize node interchangeability and point out that both transport Layer and application layer protocols should be in accordance with their peer respectively. A lightweight application- layer protocol named AgileSN is proposed, which supports node auto-detection and dynamic data parsing; the network and node models and working process of AgileSN is described in detail. On the foundation of node interchangeability, we adopt WEB browser dynamic interactive models with servers to build a suite of run-time reconfigurable virtual instrumentation platform, named IsVIE which applies component-based architecture, has the ability to build and edit applications on the fly, supports multiple data-flow and pipeline parallelism, and greatly improves throughput. IsVIP internal model is described and its performance is investigated and tested. At the end, an example is given, which applies a simulated AgileSN node and IsVIP to rapidly build a PC performance monitoring system.
