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...

Integration Retrieval of History Data and Sensing Information Using SGLN Code in Extended RFID Application
The current logistics system is constructed considering only one environment. For example, if the tag is attached to the item, the user can manage only historical data of the item. However, the user demands va...

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...

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...

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...
