The Research of Data Storage and Retrieval Scheme for Wireless Sensor Networks

Yan Liu, Weiliang Tao, Kai Liu, Ying Xu
2009 International Journal of Intelligent Engineering and Systems  
Recently, several data storage schemes have been developed to store massive sensor data in the wireless sensor networks (WSNs).  ...  In addition, a distributed index scheme is also proposed to avoid query flooding and extra data transmission.  ...  The hash function is predefined and sensor readings may be hashed to any point in the network, making most of the readings stored far away from their generating locations.  ...

Skyline Query Processing in Sensor Network Based on Data Centric Storage

Seokil Song, Yunsik Kwak, Seokhee Lee
2011 Sensors  
Therefore, a sensor network based on a data centric storage for range queries and exact matches should process skyline queries efficiently.  ...  Usually, a sensor network does not process only one type of the query, but processes various types of queries such as range queries, exact matches and skyline queries.  ...  We assume that GDCS which uses virtual grid technique is built on the sensor network. In the figure, the GDCS is based on 5 × 5 grid. The sensor network is deployed to monitor CO 2 and SO 2 .  ...

Aggregate Location Monitoring for Wireless Sensor Networks: A Histogram-Based Approach

Chi-Yin Chow, Mohamed F. Mokbel, Tian He
2009 2009 Tenth International Conference on Mobile Data Management: Systems, Services and Middleware  
As traditional query processors rely on the knowledge of users' exact locations, they cannot provide any monitoring services based on the readings reported from counting sensors.  ...  Furthermore, the histogram is designed in a way that achieves a trade-off between the energy and bandwidth consumption of the sensor network and the accuracy of monitoring services.  ...  The distributed approach injects a query to the network via a sensor node that is responsible for collecting the readings from other nodes based on the query predicate and computing the answer [26] ,  ...
