Wireless Sensor Networks (WSNs) are usually defined as large-scale, ad-hoc, multi-hop and wireless un-partitioned networks of homogeneous, small, static nodes deployed in an area of interest. Applications of sensor networks include monitoring volcano activity, building structures or natural habitat monitoring. In this paper, the authors present the problem of processing probabilistic top-k queries in a distributed wireless sensor networks. The basic problem in top-k query processing is that, a single method cannot be used as a solution to the problem of top-k query processing because there are many types of top-k query processing. The method has to be based on the situation, the classification and the type of database and the query model.
