Stream processing engines for query processing to stream data have been developed for the applications using stream data. We are researching and developing a stream processing engine named StreamSpinner. It provides a distributed stream processing scheme. In our previous work, we assume our systems are deployed on commodity PCs. Sensor nodes had to send all of sensed data to StreamSpinner on PC. But, if a stream processing engine runs on each sensor node and processes sensed data in the node, we can reduce unnecessary data transfers. So we aim to develop the distributed stream environment that includes stream processing engines on sensor nodes. In this paper, we describe the implementation of StreamSpinner on sensor nodes and propose an optimization method. Key words data stream, ditributed query optimization, distributed stream processing, sensor network 1. 1 [8] CPU 1
