Abstract :
The problem of adaptive determination of data granularity for QoS-constraint query execution is addressed. An application specifies QoS requirements with a query. Then, each node can choose the optimum data granularity for local data collection and transmission. The proposed algorithm is in a distributed fashion, and executed at each local sensor node.
