听Sumeet说过，老板的研究方向正在往CPS转移，CPS是个比较新的领域，注重计算资源与物理资源的紧密结合与协调，个人觉得，比较像Embedded System和Wireless Sensor Network的结合，主要用于一些智能系统上，如机器人，智能导航等。以下是Wikipedia对CPS的描述，比我说的权威多了。

A cyber-physical system (CPS) is a system featuring a tight combination of, and coordination between, the system’s computational and physical elements. Today, a pre-cursor generation of cyber-physical systems can be found in areas as diverse as aerospace, automotive, chemical processes, civil infrastructure, energy, healthcare, manufacturing, transportation, entertainment, and consumer appliances. This generation is often referred to as embedded systems. In embedded systems the emphasis tends to be more on the computational elements, and less on an intense link between the computational and physical elements.

Unlike more traditional embedded systems, a full-fledged CPS is typically designed as a network of interacting elements instead of as standalone devices. The expectation is that in the coming years ongoing advances in science and engineering will improve the link between computational and physical elements, dramatically increasing the adaptability, autonomy, efficiency, functionality, reliability, safety, and usability of cyber-physical systems. The advances will broaden the potential of cyber-physical systems in several dimensions, including: intervention (e.g., collision avoidance); precision (e.g., robotic surgery and nano-level manufacturing); operation in dangerous or inaccessible environments (e.g., search and rescue, firefighting, and deep-sea exploration); coordination (e.g., air traffic control, war fighting); efficiency (e.g., zero-net energy buildings); and augmentation of human capabilities (e.g., healthcare monitoring and delivery).

比如我现在做的Highway Vehicle Collision Warning System（高速公路山的汽车碰撞预警系统）也算是CPS（老板说的），每台汽车上都装有GPS定位器，DSRC收发装置，安装了我的协议的组件，计算元件（Computation Unit），以及其他一大堆传感器，探测器等。传感器，探测器等主要用于接收汽车的物理参数，而其他的主要用于实现系统，系统的运作依赖于这些物理参数。我要做的，就是让装有这些东东的车子们互动起来，形成一个预警系统。为了完成这个，得设计协议，不变式（Invariant），建模，模拟，实现等，工程“浩大”，遥遥无期。国内对CPS的研究应该很少，国外也才开始不久。CPS貌似还没有中文译名诶，相关的中文资料也很少，有时间我多翻译些，丰富博客，提高访问量，哈哈。
