Query Processing in Wireless Sensor Networks

摘要: Recently, with the fast development of sensing and wireless communication technology, sensor networks (WSNs) have been applied to monitor physical world. A WSN consists a set nodes, which are small devices limited computational resources able communicate each other located in their radio range. Network protocols ensure effectiveness between nodes provide foundation for applications. The characteristics WSNs, including energy supply resources, render design algorithms challenging interesting. Both Database communities dedicated considerable efforts make WSNs more effective efficient. In this chapter, we survey problems arisen practical applications focusing on various query processing techniques over captured data.
