摘要
传感器网络在解决底层数据源和I/O设备的异构性、处理连续查询的实时性、服务质量自适应等方面提出了许多新的挑战。提出一种基于实时CORBA的传感器网络数据流处理框架,说明了符合实时中间件规范的数据流处理系统设计的方法和特点,通过实验对该框架进行了性能测试,验证了其处理连续查询的实时性。
Sensor network in a lot of applications have proposed many new challenge to traditional real-time such as the heterogeneity of the underlying data source or I/O devices, real-time of processing continuous queries and adaptively quality of service etc. A new framework on data streams processing system based on real-time CORBA is proposed. Some key issues about design this framework, such as basic idea, method and characteristic are described. Experiments prove the real-time of our framework in processing continuous queries.
