Data aggregation is a primitive communication task in wireless sensor networks (WSNs). In this paper, we study designing data aggregation schedules under the Protocol Interference Model for answering queries. Given a network consisting of a set of nodes V distributed in a two-dimensional plane, we address different kinds of queries in this paper. First and foremost, we consider a single one-off query which requires a subset of source nodes V' C V to send data to a distinguished sink node, we… CONTINUE READING
