D2R-TED: Data—Domain ReductionModel for Threshold-Based Event Detection in Sensor Networks
(MDPI, 2018)
The reduction of sensor network traffic has become a scientific challenge. Different compression techniques are applied for this purpose, offering general solutions which try to minimize the loss of information. Here, a ...
Homomorphic Filtering for Improving Time Synchronization in Wireless Networks
(MDPI, 2017)
Wireless sensor networks are used to sample the environment in a distributed way.
Therefore, it is mandatory for all of the measurements to be tightly synchronized in order to guarantee
that every sensor is sampling the ...
Non-Invasive Forehead Segmentation in Thermographic Imaging
(MDPI, 2019)
The temperature of the forehead is known to be highly correlated with the internal body temperature. This area is widely used in thermal comfort systems, lie-detection systems, etc. However, there is a lack of tools to ...
Lightweight method of shuffling overlapped data-blocks for data integrity and security in WSNs
(Elsevier, 2021)
Wireless Sensor Networks (WSN) consist of devices with limited resources to explore and sense the environment in a cooperative way. Security, mainly in terms of guaranteeing the data integrity, is a primary issue for many ...
ZigBee Pulse Oximeter
(2011)
This work presents a prototype to adapt a standard
pulse oximeter by turning it into a wireless device using ZigBee.
Patient’s data are extracted and transmitted to the server in real
time through a Wireless Sensor ...
