In this paper a dynamic clustering scheme is introduced where a task set of sensors is formed for each task by using quadtree based addressing. The number of nodes in a task set depends on the task specifications. Hence, the sensed data is retrieved from a sensor field in the level of detail specified by users. Experiments show that quadtree based dynamic clustering scheme reduces the number of sensors involved in a query in the orders of magnitude.
