This paper presents the 300 GHz path loss measurements on a computer motherboard. In the measurement campaign, three different scenarios have been considered: a line-of-sight (LoS) scenario in the presence of a large ground plane (i.e. motherboard), a LoS scenario where the transmitter (Tx) and receiver (Rx) have different heights such as a link between the processor and memory, and an obstructed...
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 goal of this paper is to construct an dynamic secure combinatorial keying approach. We focus on heterogeneous mobile wireless sensor network environments. The proposed approach is called dynamic secure combinatorial keying approach (DSCKAD). Most of the previous work on WSN security focuses on homogeneous motes. In homogeneous WSN, sensors have the same resource specifications such as battery...
In the area of building automation, many sensor or actuator devices are tiny embedded systems which are installed throughout the building. The sensors gather information about the current environment (e.g., the temperature, number of people in a room, etc.) and the actuators interact with the environment (e.g., controlling lights, heating, or door access). A central unit controls these devices (wirelessly...
Automated LabVIEW-controlled setup for precise measurements of refractive indices of crystalline materials is described. Results of the test measurements on selected crystals are discussed.
We have developed a wireless system suitable for acquiring gastric slow wave activities and delivering electrical pulses to the stomach. The system is composed of a physically miniaturized front-end that can record slow waves from 3 channels and transmit the data to a back-end connected to a computer. A custom-made graphical user interface can display the slow waves in real-time and store them for...
The sensing, computing, and control potential of smartphones remains to be fully explored in automatic control applications. In this paper, we control the angular position of a motor test-bed using feedback from the embedded motion sensors of a smartphone while it is mounted to the test-bed. The smartphone hosts an interactive user interface which students and researchers can use to quickly and easily...
Wireless sensor network (WSN) is commonly used for localization analysis. Through sniffing receive signal strength indication (RSSI) in WSN system, localization of higher RSSI is connected automatically. This paper proposes the Raspberry-Pi (RasPi) based sensor node to sniffing RSSI and automatically connect the device to strongest RSSI. The RasPi brings the advantages of a personal computer (PC)...
In order to solve the problem of shortage of workers in large hospitals, this study design a kind of short distance wireless communication system based on brain-computer-interface (BCI) technology, it chooses the ultra-low power MCU MSP430F5438 and nRF24L01 as the core, and it includes the design of Lab view platform, brain electrical simulator, nRF24L01 wireless transceiver system and voice prompts...
Enabling the vast computational and throughput requirements of future high performance computer systems and data centers requires innovative approaches. In this paper, we will focus on the communication between computer boards. One alternative to the bottleneck presented by copper wire based cable-bound communication is the deployment of wireless links between nodes consisting of processors and memory...
Cybersecurity is one of the fastest growing concerns in the world today. Recent global events show the need for more strict measures to protect the public from cyber attacks, which has triggered an increased demand for cybersecurity professionals. Many academic institutions began offering courses covering current cybersecurity concepts to satisfy this need. Although these courses educate students...
Wireless sensor and actor networks (WSANs) deployed in a harsh environment may suffer simultaneous failures causing the network to be partitioned into disjointed parts. Connectivity restoration of these partitions is a vital issue for the reliability of the network mission. Most of the existing works in the literature mainly focus on restoring network connectivity take into account number of moving...
Open Source Hardware is widely used as enterprise standard device because it has high performance for its price. Traditional enterprise Wireless Local Area Network has the limitation of functionality and scalability by the deployed network equipment. To solve this problem, we propose ‘Web of Place Access Point’ using raspberry pi that enable to manage the scale of the network and to provide enterprise...
With the development of cooperative robotic applications, variable kinds of communication method between robots are applied. The quality of communication has directly affect to the movement of each mobile robot in system. This paper proposes an approach to control the communication between 3 mobile robots by using wireless communication. In this paper, we focus on three main parts. In the first part,...
Users consumption of video grows everyday through many different plataforms. Beyond its role on traditional broadcasting, video transmission is becoming the highest load of Internet traffic both through wired and wireless networks. Video Quality Assessment (VQA) becomes crucial for regulators, broadcasters as well as network operators. The most accurate methods to measure Video Quality are the subjective...
Wireless technology has become a new emerging technology in stakeout and security concerns industries. Study of wireless communication with energy efficiency is also a one of the most important research area. Therefore this paper presents an efficient computerized stakeout system (CSS) for stakeout and recognition purposes with the use of energy efficient ZigBee based transceiver. The designed model...
