Query Processing for Sensor Networks
Hardware for sensor nodes that combine physical sensors, actuators, embedded processors, and communication components has advanced significantly over the last decade, and made the large-scale deployment of such sensors a reality. Applications range from monitoring applications such as inventory maintenance over health care to military applications. In this paper, we evaluate the design of a que...
متن کاملQuery Processing in Wireless Sensor Networks
Recently, with the fast development of sensing and wireless communication technology, wireless sensor networks (WSNs) have been applied to monitor the physical world. A WSN consists of a set of sensor nodes, which are small sensing devices with limited computational resources able to communicate with each other located in their radio range. Network protocols ensure the effectiveness of communic...
متن کاملOptimizing Query Processing in Sensor Networks
Query processing in sensor networks has recently received significant attention from the research community. Processing queries in an energy efficient manner is a crucial challenge. There exists numerous ways to process a query in sensor networks. Choosing an efficient way to process the query is essential for query optimization. In this paper, we consider a query optimizer for sensor networks....
متن کاملQuery processing Algorithm in Wireless Sensor Networks
Sensors have a function to gather environmental data in sensor networks. They operate by limited, small-size battery depending on applications. Thus there are several kinds of research efforts to make better use of local energy. In this paper, we propose multi-attribute query processing algorithm (Section Bit based scheme (SB)). In the initial setup, routing path is determined based on parent-c...
متن کاملEfficient Iceberg Query Processing in Sensor Networks
The iceberg query finds data whose aggregate values exceed a pre-specified threshold. To process an iceberg query in sensor networks, all sensor data have to be aggregated and then sensor data whose aggregate values are smaller than the threshold are eliminated. Whether a certain sensor datum is in the query result depends on the other sensor data values. Since sensor nodes are distributed, com...
