普适计算是一个新概念，它可以被定义为一种技术，它可以在任何有用的地方使用，并且在经济上可行，期望找到一个传感器。传感器网络被认为是构建泛在系统的关键技术。在一个典型的无处不在的网络中，传感器节点的小物理尺寸通常是必须的，因为它致力于不显眼地集成到生活、工作、科学、工业和其他环境中。这意味着设备的传感、计算和通信能力的高度集成，同时满足特定于应用程序的需求。使用无线基础设施，无处不在的技术应该在各种情况下连接物理环境，如军事、家庭、工作、健康、工业等。这使得无处不在的传感的实现高度特定于应用。接口问题以及不同技术之间的互操作性是系统设计中要求最高的部分。这里的诸多限制为传感、节能、通信、安全等各个工程领域带来了挑战。这些问题往往是互补耦合的，这使得寻找最优解的过程更加复杂。
Ubiquitous computing is a new concept that could be defined as a technology which can be available anywhere that it is useful and economically viable to expect to find a sensor. Sensor network is recognized to be a key technology for building a ubiquitous system. Small physical dimensions of sensor nodes are often one of the musts in a typical ubiquitous network, since it is dedicated to unobtrusive integration into living, working, scientific, industrial, and other environments. This implies high integration of sensing, computing, and communication capabilities of the devices meeting at the same time application-specific demands. Using mostly wireless infrastructure, ubiquitous technologies are supposed to interface the physical environment in various circumstances such as military, home, working, health, industry, etc. This makes implementation of the ubiquitous sensing highly application-specific. Interfacing issues along with the interoperability between different technologies are the most demanding parts of the system design. Many constraints here bring up challenges in various engineering fields such as sensing, energy conservation, communication, security issues, etc. These issues are often complementary coupled, which makes the process of finding the optimal solution more complicated.
