  • Abstract A wireless sensor network is an emerging technology that enables remote monitoring
    of larger scale. Data-centric storage is an effective and important technique in the wireless
    sensor networks. It stores the sensing events according to their attributes values of events
    by mapping them to some nodes in order to avoid routing all the values outside the
    network and flooding the queries. There are many attributes with range value in an event,
    thus, the sensor will use the multi-dimensional range query to retrieval data. In this paper,
    we propose a data storage and range query method for multi-dimensional attributes in
    wireless sensor networks. The main idea is to map multi-dimensional events to their
    corresponding range spaces and to build an in-network distributed data structure for
    efficiently getting the data of multi-dimensional range queries. Simulations have shown
    that our proposed scheme can reduce energy consumption.
