LoRa-based (Long Range Communication based) localization systems make use of RSSI (Received Signal Strength Indicator) to locate an object properly in an outdoor environment for IoT (Internet of Things) applications in smart environment and urban networking. The accuracy of localization is highly degraded, however, by noisy environments (e.g., electronic interference, blocking). To address this issue,...
Pervasive and ubiquitous computing increasingly relies on data-driven models learnt from large datasets. This learning process requires annotations in conjunction with datasets to prepare training data. Ambient Assistive Living (AAL) is one application of pervasive and ubiquitous computing that focuses on providing support for individuals. A subset of AAL solutions exist which model and recognize...
In this paper, we propose a video-based indoor positioning system (VIPS) to provide centimeter-grade localization for the Internet of Things (IoT). The VIPS system integrates installed surveillance cameras with the IoT to provide highly-accurate positioning information to indoor people, which efficiently enables microlocation-aware IoT applications and services in smart environments. VIPS can estimate...
With the popularity of Internet of Things, lots of resource constrained devices equipped with sensors and actuators are pervasively deployed to compose a smart environment, and Big Data are obtainable for a system to do further analytics thus to achieve human-centric purposes. One such human-centric system is a smart home which analyze Big Data to recognize contexts and their corresponding preferences...
Clustering is a good method to increase WSN lifetime and particularly for smart environment. In this paper, we present fuzzy position based routing for clustered sensor network. It is very useful for the smart environment applications of wireless sensor network without GPS support. The destinations could be located with ambiguous position vectors, and the long time and energy consumption of requesting/replying...
Classroom usually has a timetable plate embedded on the wall near the front door. However, the only purpose for displaying classroom's timetable cannot fulfill the future digital classroom requirement. They need more automatic, integrated, and intelligent functionality in the classroom environment. Besides, the vision of future smart classroom is to select sustainable technology solutions that have...
Current Intelligent Transportation Systems tends to be integrated in smart environments where sensors are provided with processing and communication capabilities. This is the case of the vehicle detection system proposed in this paper. The ARM-based video processor not only deals with the video processing algorithms, but also takes advantage of the networking capabilities using an embedded operating...
