Summary: | 碩士 === 大同大學 === 資訊經營學系(所) === 96 === 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.
