NeTS-NOSS: Fluid Software Infrastructure for Wireless Sensor Networks

传感器网络代表了一种新的颠覆性技术，可能会对整个十年的社会和研究产生巨大影响。编程传感器网络是一个困难和容易出错的任务，因为它们经常表现出连续的重新配置所造成的环境因素和能源消耗，引入新的传感器，以及存在的各种形式的移动性内部和外部的网络。该项目正在开发一个灵活的软件基础设施，允许程序员将传感器网络视为一个共享的，不断发展的，地理分布的，通用的计算环境。这种基础设施实现了前所未有的灵活性，流动性和适应性的结构应用程序的协调移动的代理社区。代理能够进入和退出传感器网络，并通过利用新形式的代码和状态移动性和动态组合来构建和发展复杂的应用程序。他们能够保持应用程序的完整性和它的物理环境的关系，通过利用新的协调技术，包括时空维度的监测。拟议的软件基础设施的一个显着特点是它的统一处理的所有形式的移动性遇到的传感器网络应用程序：实体在物理环境中的移动，用户的移动，移动的代码在网络内和跨网络边界，甚至构成网络的传感器的移动。该项目正在创建第一个基于代理的软件基础设施，用于开发灵活的传感器网络应用程序。它允许程序员设计可以在需要时部署的应用程序，可以共享网络资源，可以将其网络使用限制在感兴趣的区域，可以适应网络和环境条件，并可以减少能源消耗。

Sensor networks represent a new disruptive technology likely to have a great impact on both society and research throughout this decade. Programming sensor networks is a difficult and error prone task as they often exhibit continuous reconfiguration caused by environmental factors and energy depletion, the introduction of new sensors, and the presence of various forms of mobility internal and external to the network. This project is developing a flexible software infrastructure that allows the programmer to treat the sensor network as a shared, evolving, geographically distributed, general-purpose computing milieu. This infrastructure achieves an unprecedented level of flexibility, fluidity, and adaptability by structuring applications in terms of a community of coordinating mobile agents. Agents are able to enter and exit the sensor network and to construct and evolve complex applications by exploiting new forms of code and state mobility and dynamic composition. They are able to maintain the integrity of the application and its relation to the physical environment being monitored by exploiting new coordination techniques that include a spatiotemporal dimension. A distinguishing feature of the proposed software infrastructure is its unified treatment of all forms of mobility encountered in sensor network applications: movement of entities in the physical environment, movement of the user, movement of code within the network and across network boundaries, and even the movement of sensors making up the network. This project is creating the very first agent-based, software infrastructure for the development of flexible sensor network applications. It allows programmers to design applications that can be deployed when needed and as needed, can share network resources, can limit their network usage only to regions of interest, can adapt to network and environmental conditions, and can reduce energy consumption.
