The cyber-physical system (CPS) paradigm offers tremendous advantages in many application scenarios and promises a solution to a large number of pressing individual and societal needs. However, their properties such as heterogeneity, lack of perimeter protection, longevity, pervasive diffusion and strictly constrained resources also give rise to new security vulnerabilities. In this paper, we discuss...
The Internet of Things (IoT) technology, based on the wireless sensor network, is developing rapidly and permeating into agriculture including livestock farming. Our research focuses on the problem that current industrial IoT system for livestock farming is tightly coupled, hard to expand, and with poor network performance. In this paper we proposed an integrated framework of smart livestock farming...
There is an increasing demand in designing heterogeneous networks, where various low-power wireless radios such as ZigBee and Bluetooth devices coexist, while sensing devices may generate traffic with different intervals. In this work, we devise an architecture of a cross layer controller, encompassing a software defined radio at the data plane to manage radio access, and a software defined networking...
This paper represents a conceptual design of a flight data acquisition system for small scale unmanned aerial vehicles. The system consists of three components-the unmanned aircraft, data acquisition hardware and display. The acquired data from various sensors of the acquisition system are stored in on board storage device and the data is essential for achieving situational awareness of the control...
Mobility-on-Demand (MoD) services can be enhanced through use of Autonomous Vehicles (AVs) to reduce manpower costs (among other benefits), and use of multiple classes of vehicles to expand service coverage and accessibility. This work presents a functional proof of concept MoD system accessible via mobile phone to utilize three classes of vehicles in combination: a road car, buggy, and mobility scooter...
Multi-robot systems are reliable and faster at searching and retrieving targets in times of crises as compared to single-robot systems. They are also better compared to manned missions as they are more resistant to hazardous conditions. In this work a method to deploy a swarm of robots to scan and retrieve the targets stuck in a disaster situation is deliberated. The multi-robot system developed is...
White Space (WS) Networking crucially relies on the active monitoring of spatio-temporal spectrum usage (to identify WS opportunities). To achieve this, one way is to gather spectrum data via wide-area sensor deployment and construct better Radio Environment Maps (REMs) with spatial models such as Kriging and Gaussian Process (GP). An economically viable alternative is via incentivized crowdsourcing,...
In order to realize the function of accurate measurement, multipoint collection and wireless transmission on various environmental monitoring factors in the workshop, a workshop environment monitoring system is proposed based on the technology of internet of things. A number of wireless monitoring nodes are set up in each workshop to collect a variety of environmental information, then transmit the...
In the last 20 years, most vehicles have seen a large increase in complexity of the electronic and software systems, e.g. the number of electronic control units (ECUs) increased to over 70 in many cars and connectivity to the Internet or over Bluetooth is possible. In combination, the increased complexity and a large attack surface due to the connectivity makes it necessary to investigate the security...
Real-time monitoring of physiological data can reduce the likelihood of injury in noncombat military personnel and first-responders. MIT Lincoln Laboratory is developing a tactical Real-Time Physiological Status Monitoring (RT-PSM) system architecture and reference implementation named OBAN (Open Body Area Network), the purpose of which is to provide an open, government-owned framework for integrating...
The goal of this paper is to establish a framework called SMOME for evaluating the marginal utility of adding smart sensing and metering hardware to residential premises, in terms of efficiency improvement (reduction in energy consumption) and economic benefits (reduction in energy cost). In order to isolate the effect of smart home technologies on energy efficiency, it is assumed that no changes...
Inferring activities on smartphones is a challenging task. Prior works have elaborated on using sensory data from built-in hardware sensors in smartphones or taking advantage of location information to understand human activities. In this paper, we explore two types of data on smartphones to conduct activity inference: 1) Spatial-Temporal: reflecting daily routines from the combination of spatial...
In this work, we present a fast computational structure for the discrete Hirschman Transform (FHT) family on Field Programmable Gate Arrays (FPGAs). Compared to the traditional FFT, the FHT has better performance in spectral estimation, FIR convolution, and especially in Compressive Sensing (CS). We implement our design of the DHT by using circular shifting of shorter terms of the FFT. This algorithm...
With the rapid development in the field of solar energy, photovoltaic (PV) modules are being used in a wide range of moving applications like cars, trains, ships and a number of space applications that are subjected to dynamic partial shading. In such applications the power-voltage (P-V) characteristics of the PV module continuously changes with time. The conventional Maximum Power Point Tracking...
With the improvement in standard of living of human beings, better home/office environment is required. Nowadays, intelligent home designs are becoming a trend in which intelligence can be built-in to provide improved user comfort at an incremental cost. However, many of the mature systems do not care about the energy savings. This paper presents a smart home solution with energy conservation in mind...
Compared with the infrared focal plane array (IRFPA) based on amorphous silicon (α-Si), IRFPA based on vanadium oxide (VOx) has the advantages of big temperature coefficient, low noise and so on. Therefore, it is believed that VOx IRFPA has important application in both military and civil field. In this paper, the designs of driving module and signal processing module of VOx IRFPA are proposed. Firstly,...
The KIT Energy Smart Home Lab is a smart residential building comprising building automation systems, metering systems, sensors, intelligent home appliances, heating, ventilation, and air-conditioning equipment, distributed generation, and energy storage systems. Recently, to facilitate fully functional power hardware-in-the-loop simulations and evaluations, the laboratory is extended by a hybrid...
Wearable health-monitoring systems must achieve a balance between the often opposing goals of hardware overhead and classification accuracy. Prior works have presented various approaches to dynamically scale the accuracy of these systems as a function of available resources. In this paper, we present a framework which retroactively improves the accuracy of prior estimates when resources become available,...
A real-time simulator is an essential tool for swiftly designing and verifying embedded time-sensitive and/or real-time applications in both academia and industry. An FPGA-based wireless extensible hardware-in-the-loop (WEX-HIL) real-time simulator was developed for designing subsystems of an electrical vehicle (EV). The WEX-HIL platform is capable of providing a design and test environment of virtual...
Research shows that the poor quality of science education and related areas in the Brazilian basic education has been negatively affecting professionals training in research and scientific development, also contributes to high rates of evasion of STEM graduation courses. Also, scientific illiteracy are harmful to society, once it's members losses analytical judgment capability and by that are more...
