Abnormal behaviors in industrial systems may be early warnings on critical events that may
cause severe damages to facilities and security. Thus, it is important to detect abnormal …

Recently, various research efforts have been conducted to develop strategies for accelerating
multi-dimensional query processing using the Graphics Processing Units (GPUs). Well-…

Multi-criteria decision making is one of the most critical and yet most challenging components
in modern enterprise business intelligence. It is well known that complex business …

In clustering-based approaches, cluster heads closer to the sink are usually burdened with
much more relay traffic and thus, tend to die early. To address this problem, distance-aware …

Recently, various research efforts have been conducted to develop strategies for accelerating
multi-dimensional query processing using the graphics processing units (GPUs). However…

The primary goal of this work is to minimize the maximum error rate with time leveraging
range query and crowdsourced update strategy for fingerprints database which still remains …

PEGASIS, a chain-based protocol, forms chains from sensor nodes so that each node transmits
and receives from a neighbor. In this way, only one node (known as a HEAD) is selected …

Skyline queries continue to attract attentions since the skyline operator was first proposed in
2001. In this paper, we propose a fast skyline computation approach, called HashSkyline, …

We propose a novel scheme that aims to determine the optimal number of clusters based on
the field conditions and the positions of mobile sink nodes. In addition, we merge algorithms …

WiFi positioning system (WPS) is the best approach for the indoor navigation system in view
of cost, availability and performance. Many researcher have been studied the WiFi based …
