It is well understood that data-acquisition by distributed sensors and subsequent transmission of all the acquired data to the cloud will produce a “data deluge” in next-generation wireless networks leading to immense network congestion, and data back-logs on the server which will prevent real-time processing and control. This motivates in situ data analytics in energy-constrained wireless sensor...
In this paper, we propose an energy efficient motion detection and power management mechanism, called sleepyCAM, for wireless camera sensor nodes that do not otherwise support low-power modes. In the proposed solution, a low-power sensor node accompanied with a Pyroelectric Infrared (PIR) sensor and a relay is used to detect motion and manage the power usage of a high-power and high-resolution camera...
Exchange of image information is one of the main features of a camera network. In order to exchange a large amount of information, a platform with good communication speed is needed. In this study, we designed and implemented a specialized camera network platform using Wi-Fi Direct devices. This platform can provide various services to other devices within the same network. We designed the platform...
The field of insertable laparoscopic robotic camera is gaining increasing attentions from researchers, surgeons, and also patients. Although many insertable laparoscope prototypes have been introduced, few of them get rid of the encumbrance tethering cable. In this paper, we proposed a hardware architecture for a magnetic actuated robotic surgical (MARS) camera, which facilitates a cable-free fully...
Internet of things (IOT) can be considered as a combination of effective hardware and impressive software which results in smart objects which are able to communicate and interact among themselves. However, data flow accuracy between two movable devices is a growing problem. This paper proposes and implements two approaches: Discrete Cosine Transfer (DCT) and Inter-Process Communication (IPC) for...
The article presents the Argus project. The aim of the project is the development of an automatic photography system. Argus is built on a special hardware system (central server, minicomputers with NFC(Near Field Communication) card readers and cameras) and it is controlled by a specific software system. The software system contains a server, a web application and a desktop application, which is running...
Hand Gesture technology have existed and being used in many fields from quite a long time, but it is not being so common in daily use. The reason is that in the existing gesture recognition systems power consumption is quite high. In addition to that computational resources used in existing system increase their cost which limits their usage in low-end devices. To overcome this problem we have used...
Detailed procedure for laboratory set up of Miniature Aerial System (MAS) simulator. MAS have three parts viz., Miniature (unmanned) air vehicle (MAV), wireless communication link and ground control station (GCS). For testing, flying MAV every time is more expensive and not viable. To overcome this problem, a laboratory based Miniature Aerial Vehicle Flight Simulator (MAVFS) has been developed by...
In order to solve the problem of the traditional intelligent mower, which cannot cover the lawn area and operate complexly, a visual, wireless, autonomous mower system via machine vision is designed. Firstly, collect the image information of locale dynamically by the real-time camera which erected on the high bracket, and display on the monitor of PC, then draw a few mowing range or mowing patterns...
Smartphones are frequently used to shoot and share videos online and emerging applications, such as Augmented Reality, will increase the usage of the camera. Unfortunately, shooting and streaming video drains a modern smartphone's battery very quickly. We report results from a measurement study to dissect the smartphone energy consumption when using such an application. Our main findings are that...
A taxonomy of wireless visual sensor networks for surveillance offers design goals that try to balance energy efficiency and application performance requirements. SWEETcam, a wireless smart camera network platform, tries to address the challenges raised by achieving adequate energy-performance tradeoffs.
Visual Sensor Networks (VSNs) enable enhanced three-dimensional sensing of spaces and objects, and facilitate collaborative reasoning to open up a new realm of vision-based distributed smart applications including security/surveillance, healthcare delivery, traffic monitoring, just to name a few. However, such applications require sensor nodes that can efficiently process large volumes of visual information...
For the latest development in the direction of embedded system and wireless network, this paper describes wireless image transmission based on the embedded system. It establishes the hardware platform of the embedded system. Microprocessor S3C2440A will be the core, USB camera will be the image acquisition device and wireless network card will be the wireless transmission equipment. The software development...
Initially, we point out that hardware trust is pretty important to a trusted computing platform based on prior work. Then we propose the notion of measuring hardware trust. We also analyze key factors needed to be considered when designing a hardware-measurement architecture, and give an outline of our approach. Next, we show the measurement result and further discuss some other applications of hardware...
