一种基于元组空间的智能传感器协同感知机制

随着具有一定计算能力和无线通信能力的智能传感器(称为mote)的出现,越来越多的物联网应用可以实现对环境及其变化的就地感知、就地决策和就地反应.但因为mote的感知能力和感知范围有限,它们需要协同感知才能更全面地感知环境的状态,才能更好地适应环境的变化.而传统的mote协同感知的实现方法要求开发人员过多地关注mote之间的交互逻辑,并且mote应用也无法适应复杂环境的不断变化.为了避免开发人员在交互逻辑上花费过多的精力,同时保障开发出来的mote应用系统能够适应不稳定的外界环境,提出了一种基于元组空间的mote协同感知支撑机制,使得mote之间的协同感知过程(包括交互的建立过程以及对环境变化的适应过程)对开发人员完全透明.最后实现了一个简单的应用场景,展示了该方法如何满足功能需求以及在环境发生变化时如何对环境进行适应.

Collaborative Sensing Mechanism for Intelligent Sensors Based on Tuple Space

With the emergence of intelligent sensors (referred to as motes in this paper) which have certain kinds of computing and wireless communication ability, more and more IoT (Internet of Things) applications can be implemented to sense, judge and react locally according to the environment and its changes. Because of the limitation of motes' awareness and perception scope, they need collaborative sensing to be fully aware of environment states and to better adapt to the changing environment. Traditional mote collaborative sensing mechanisms require developers to focus too much on interaction logics and can hardly adapt to the changing environment. To avoid over spending effort on interaction logics while ensuring that the projects can adapt to the unstable environment, this paper proposes a tuple space based collaborative sensing mechanism for intelligent sensors. It makes communication process completely transparent to developers. This paper also implements a simple demonstration to show how to use this mechanism to build system and how this system adapts to the environment.
