Chapter and Conference Paper
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 ...

Chapter and Conference Paper
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...
Article
This paper investigates the problem of inconsistent states of radio frequency identification (RFID) tag data caused by incomplete execution of read/write operations during access to RFID tag memory. Passive RF...
Article
In recent years, there has been a growing need for complex event processing (CEP), ranging from supply chain management to security monitoring. In many scenarios events are generated in different sources but a...
Chapter and Conference Paper
As the recent growth of RFID technologies, a goal of productivity has been achieved in various industry areas where the technologies are used. With this change, a number of RFID logistics systems have been stu...
Chapter and Conference Paper
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...
Chapter and Conference Paper
Recently, RFID technology has become one of essential technologies, which applies to a wide area of applications such as logistic, manufacture and pharmacy. Testing of RFID middleware is a critical process to ...
Chapter and Conference Paper
Since raw RFID streaming data is continuous, voluminous, incomplete, temporal and spatial, RFID applications cannot directly make use of it. As a key component of RFID systems, an RFID middleware needs to clea...
Chapter and Conference Paper
RFID technology is being applied to the wide field of distributions and logistics for item-level tracking of tagged goods. Recently, spoilage and abnormalities of product in Blood Supply Chain (BSC), Cold Chai...
Chapter and Conference Paper
Huge amount of goods passes to the customers, which are produced in factories or packaged by the box in wholesalers. At this time, if does not inspect the exactly number of products in the box while packaging,...
Chapter and Conference Paper
Evaluation of RFID middleware is a complex process due to its cost for constructing a test bed involving RFID readers and tags. An input dataset of the RFID middleware is a tag event stream from connected read...
Chapter and Conference Paper
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....
Chapter and Conference Paper
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...
Chapter and Conference Paper
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...
Chapter and Conference Paper
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...
Chapter and Conference Paper
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...
Chapter and Conference Paper
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...
Chapter and Conference Paper
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...
