In order to sense large area of network, huge number of sensor nodes is required. In this kind of arrangement, sensors which are nearby often sense similar readings due to their temporal and spatial correlation. In this paper, an in-network query processing model called as AQP (autonomous query processing) which handles both spatial and value based queries has been proposed. This protocol uses repositories which are sensors and acts as data storage by storing set of information from cluster heads. For query processing, only repositories need to be contacted to respond to queries. AQP is autonomous since it doesn’t depend on any central node neither for managing data and nor for query processing. This protocol has been implemented using NS 2.33 and gradual increase in its efficiency with existing method is shown in result graph.
