近年来，随着传感技术和无线通信技术的快速发展，无线传感器网络（WSNs）已被应用于对物理世界的监测。WSN由一组传感器节点组成，这些传感器节点是位于其无线电范围内的具有有限计算资源的小型传感设备，能够相互通信。网络协议保证了传感器节点间通信的有效性，为无线传感器网络的应用提供了基础。无线传感器网络的特点，包括有限的能源供应和计算资源，使得无线传感器网络算法的设计具有挑战性和趣味性。数据库和网络社区都做出了相当大的努力，使无线传感器网络更加有效和高效。在本章中，我们调查了wsn在实际应用中出现的问题，重点是对捕获的传感数据的各种查询处理技术。
Recently, with the fast development of sensing and wireless communication technology, wireless sensor networks (WSNs) have been applied to monitor the physical world. A WSN consists of a set of sensor nodes, which are small sensing devices with limited computational resources able to communicate with each other located in their radio range. Network protocols ensure the effectiveness of communication between sensor nodes and provide the foundation for WSN applications. The characteristics of WSNs, including the limited energy supply and computational resources, render the design of WSN algorithms challenging and interesting. Both the Database and Network communities have dedicated considerable efforts to make WSNs more effective and efficient. In this chapter, we survey the problems arisen in practical applications of WSNs, focusing on various query processing techniques over captured sensing data.
