A Study on MapReduce Processing for Multi-dimensional Continuous Query
A huge volume of sensor stream data can be efficiently handle with the MapReduce framework for processing multi-dimensional continuous queries. The MapReduce originally has been used for batch processing, not ...

A Scalable Object Based Discovery Service for Global Tracing of RFID Products
Radio-Frequency Identification (RFID) technology can provide global visibility for each product by the Discovery Service (DS) of EPCglobal, the de facto international standard for RFID. Only the role of a DS h...

A Reprocessing Model Based on Continuous Queries for Writing Data to RFID Tag Memory
This paper investigates the problem of writing data to passive RFID tag memory and proposes a reprocessing model for assuring the atomicity and durability of writing transactions in volatile RF communications....

Reordering of Location Identifiers for Indexing an RFID Tag Object Database
The query performance for tracing tags depends upon the distribution of tag trajectories in the data space. We examine a more efficient representation of tag trajectories by means of ordering the set of domain...

The Self-relocating Index Scheme for Telematics GIS
The history management of vehicles is important in telematics applications. To process queries for history data, trajectories, we generally use trajectory-preserving index schemes based on the trajectory prese...

Time Parameterized Interval R-Tree for Tracing Tags in RFID Systems
For tracing tag locations, the trajectories should be modeled and indexed in a radio frequency identification (RFID) system. The trajectory of a tag is represented as a line that connects two spatiotemporal lo...

A Progressive Reprocessing Transaction Model for Updating Spatial Data in Mobile Computing Environments
Mobile transactions for updating spatial data are long-lived transactions that update local copies of the mobile platforms on disconnection. Since a mobile transaction is physically separated from its global t...

Concurrent Updating of Large Spatial Objects
The update transactions to be executed in spatial databases have been usually known as interactive and long duration works. When a spatial object has a very large geometry of which size is larger than the scre...

Growing Node Policies of a Main Memory Index Structure for Moving Objects Databases
Recent studies on main memory index structures focus mainly on cache-conscious structures to minimize L2 cache misses; for example, in one dimensional data, CSB+-tree eliminated pointers to pack more entries i...

Declustering of Trajectories for Indexing of Moving Objects Databases
Efficient storage and retrieval of trajectory indexes has become an essential requirement for moving objects databases. The existing 3DR-tree is known to be an effective trajectory index structure for processi...

A Log-Based Cache Consistency Control of Spatial Databases in Mobile Computing Environments
In mobile client/server computing environments, mobile clients make access to their server to get interested data and then are disconnected because of high cost of wireless communication. Mobile clients usuall...

Dynamic Splitting Policies of the Adaptive 3DR-Tree for Indexing Continuously Moving Objects
Moving-objects databases need a spatio-temporal indexing scheme for moving objects to efficiently process queries over continuously changing locations of the objects. A simple extension of the R-tree that empl...
