A wireless sensor network comprises a plurality of nodes that communicate over wireless communication links. At least one of the plurality of nodes receives sensor data from a sensor. The wireless sensor network is queried by specifying a set of events of interest. For each event of interest included in the set of events of interest, a producer node included in the plurality of nodes identifies when that event of interest occurs and, when that event of interest occurs, transmits event data related to that event of interest to a consumer node included in the plurality of nodes. The query is expressed in a discrete event process algebra that is used to manage processing performed to implement the query.
