Continuous Query Processing of Spatio-temporal Data Streams in PLACE
The tremendous increase in the use of cellular phones, GPS-like devices, and RFIDs results in highly dynamic environments where objects as well as queries are continuously moving. In this paper, we present a continuous query processor designed specifically for highly dynamic environments (e.g., location-aware environments). We implemented the proposed continuous query processor inside the PLACE...
متن کاملMobiPLACE*: A Distributed Framework for Spatio-Temporal Data Streams Processing Utilizing Mobile Clients' Processing Power
The problem of continuous spatio-temporal queries’ processing was addressed by many papers. Some papers introduced solutions using single server architecture while others using distributed server one. In this paper, we introduce MobiPLACE*, an extension to PLACE* [13] system, a distributed framework for spatio-temporal data streams processing exploiting mobile clients’ processing power. We will...
متن کاملManaging Moving Objects in the Context of Streaming Spatio-Temporal Data
Managing moving objects in DSMS has recently been a focus of a relatively intense research. In this paper, we are concerned with data streams containing a location of a moving object at any time instant. Instead of using spatial and time instant data types separately, for representing spatio-temporal characteristics of data streams, we propose a unified approach based on specialized temporal da...
متن کاملReal-Time spatio-temporal data mining with the “Streamonas” Data Stream Management System
Data Stream Management Systems (DSMSs) have not yet reached a mature enough stage to effectively run data mining algorithms, as they still face challenges within the streaming environment. Streamonas DSMS, as presented in a recent publication, is the first DSMS to reach the maximum level of difficulty supported by the Linear Road Benchmark which is 10 Expressways. The powerful engine of Streamo...
متن کاملLetter from the Editor - in - Chief The Data Engineering Conference ICDE
In this paper, we overview the PLACE server (Pervasive Location-Aware Computing Environments); a scalable location-aware database server developed at Purdue University. The PLACE server extends data streaming management systems to support location-aware environments. Location-aware environments are characterized by the large number of continuous spatio-temporal queries and the infinite nature o...
