Two important objectives in processing a continuousmonitoring queries (CMQ) are: (1) to minimize the processingoverheads, especially in communication and query evaluation;and (2) to provide temporally consistent sensor data for queryevaluation. The first one is important to normal operations ofsensor devices while the second one is to ensure the correctnessof the query results. We propose periodic pushing schemes,called PerPush and ConPush, to aggregate the sub-query resultsof a CMQ. To further improve the performance, we propose theSequential Pushing (SeqPush) scheme for aggregating thesensor data values generated by the sensor nodes which areclose to each other. The pushing path in SeqPush follows asequential pattern according to the semantic of the queries andthe results of evaluation of the sub-queries at the nodesparticipating in the CMQ.
