摘要：

Wireless Sensor Networks (WSN) are considered as a large distributed database, which can be queried using SQL-like language. Several Query Processing Systems (QPS) have been proposed, to extract data from WSN. Many WSN-based applications require fresh data and strict deadlines when they receive responses from the WSN. However, the QPS are not dedicated to ensure the temporal constraints like the temporal validity of data and the queries deadlines. In this paper, we propose a new model for Real-Time Query Processing System (RTQPS) in order to guarantee temporal constraints in WSN. Our system is based on the QPS architecture, including some components of real-time database management system (DBMS). RTQPS ensures efficient query dissemination and data collection. It provides deadline controllers to ensure real-time constraints and real-time schedulers to meet query deadlines. We have carried out many simulations in order to validate our approach.
