摘要： Algorithms and concepts for maintaining uniform random samples of streaming data and stream joins. These algorithms and concepts are used in systems and methods, such as wireless sensor networks and methods for implementing such networks, that generate and handle such streaming data and/or stream joins. The algorithms and concepts directed to streaming data allow one or more sample reservoirs to change size during sampling. When multiple reservoirs are maintained, some of the algorithms and concepts periodically reallocate memory among the multiple reservoirs to effectively utilize limited memory. The algorithms and concepts directed to stream joins allow reservoir sampling to proceed as a function of the probability of a join sampling operation. In memory limited situations wherein memory contains the sample reservoir and a join buffer, some of the stream join algorithms and concepts progressively increase the size of the sampling reservoir and reallocate memory from the join buffer to the reservoir.

摘要： In at least some example embodiments, a data processing apparatus is configured to recover a network connection within an application framework that hides sockets by separating acquisition and processing into different threads of the same process, and, thus, when the processing thread is unable to retrieve a frame from the acquisition thread, the data processing device may terminate the acquisition thread with impunity since all important application state may safely remain within the processing thread.
