In this paper, an android based SAMS (Smart Activities Monitoring System) application for smart phone is proposed. This application is developed with the aim of increasing the national security in Pakistan. In last decade, various incidents including militant attacks and ransom-demands have been reported in which cell phones played a central role in communication between the culprits. The tracking...
The proliferation of Unmanned Aerial Vehicles (UAVs) raises a host of new security concerns. Our research resulted in a prototype UAV monitoring system, which captures flight data and performs real-time behavioral monitoring. If a behavioral anomaly is found, the system will alert the operator. In addition, a novel visualization system tracks the real time behavior and flight of multiple UAVs. Our...
Numerous works have investigated the vulnerability of Global Navigation Satellite Systems (GNSS) against attacks. Upcoming systems make provisions for cryptographic civilian signal protection. However, this alone does not fully protect GNSS-based localization. In this paper, we show that attacks at the physical layer, without modification of navigation messages, can be severely effective. We analyze...
Critical systems, like Unmanned Aerial Systems (UAS) operate in uncertain environments and have to face unexpected obstacles, weather changes and sensor, hardware or software failures. Therefore, a health management system is needed to detect and locate the failure in real time. In this paper, we propose a Field Programmable Gate Array (FPGA) implementation based on a Bayesian network (BN) representation,...
As the increase in demand for electricity is not been supplied by adequate increase in electrical power generation, the pressure on the electric grids is tremendously growing. so, reliability and integrity is becoming more difficult, sometimes, which may leads to large blackout. In addition, the grid experiences sudden changes due to the inability of the relays to adjust to the prevailing network...
Ionospheric propagation is harmful for the electromagnetic signals broadcast by Global Navigation Satellite System (GNSS) satellites, mainly because of the presence of electron density anomalies. GNSS receivers are indeed of primary importance in scintillation and Total Electron Content (TEC) monitoring, especially at low and high latitudes, where scintillations are more frequent. Professional dual...
Nowadays, mobile devices become more and more powerful and affordable. This is the reason why, side by side with the evolution of smart phones, the applications for those devices have also evolved. One type of applications that are widely used almost daily are the ones that help tracking the user's location. We propose a collaborative mobile application that can help a group of users doing outside...
To control and preventing volcanic risk, are used different devices where many parameters are monitored that provide insight into the state of a volcano. This paper presents the design of system for monitoring the volcano seismicity. This system is composed of the module of acquisition data, the power module, the peripherals for communicate remotely and GPS to get time synchronization. This system...
This article performs a proposed design of a communications system based on the Automatic Identification System (AIS), to control ships crossing Magdalena River in Colombia. Ships crossing the river will be monitored in order to track them in real time and receive information related (course, ship type, dimensions, speed, destiny, etc.). In this paper are presented studies concerning geography in...
Global Positioning system (GPS) is a satellite navigation system, which provides users with positioning, navigation, and timing (PNT) services. Ionospheric scintillations not only can reduce the accuracy of GPS/Satellite Based Augmentation System (SBAS) receiver pseudo-range and carrier phase measurement but also can result in a complete loss of lock on a satellite. To enable the study of Ionospheric...
In Indonesia, river water plays important roles in human life; for example, for transportation and economic activities of the inhabitants. However, industrial, agricultural and domestic water is discarded into rivers directly in many developing countries, since drainage systems have not been completely constructed. Water quality monitoring using radio-controlled submarine provide an opportunity to...
An underwater glider we are developing for virtual mooring will be able to remain in a designated area for several years, moving between the sea surface and the seafloor up to 2,100 m deep, monitoring the sea environment. It will be able to sleep on the seafloor or while drifting in water to extend the monitoring duration. As described herein, we present results of heading-control tests conducted...
Smart phones are increasingly becoming popular. All Smart phones have rich set of sensors, which can be used to provide driver assistant services. Services such as, road traffic information and road condition monitoring, to provide such services system needs sensors such as GPS, Gyroscope, Accelerometer. Now days Smart phones are coming with these sensors. Smart phone camera sensor, one of the most...
During its whole service life, a building can be subjected to operational and environmental forces usually present, or to episodic seismic loadings (earthquakes). An automated smart building is a house capable of self-monitoring in order to signal the need of maintenance, when a reduction in performance levels is detects, or to signal the need of action if there are some structural problems. One of...
In recent years, paratransit is a very important transportation for serving disabilities. Currently, the dispatching center has arranged for driver's tasks which carry passengers. The operators are difficult to efficiently monitor each vehicle's attendance and diving state. The rate of vehicular utilization is low and the problem of service inefficiency appears. Passengers cannot know the arrival...
Crop monitoring and harvesting by ground robots on mountain vineyards is an intrinsically complex challenge, due to two main reasons: harsh conditions of the terrain and reduced time availability and unstable localization accuracy of the GPS system. In this paper is presented a cost effective robot that can be used on these mountain vineyards for crop monitoring tasks. Also it is explored a natural...
The people who use inner city public transportation vehicles want to get information about the current status of the public transportation vehicles and they want to know the travel time of the vehicles both while travelling and waiting at the bus stops. In this study, a smart bus stop-passenger information system was developed in order to enable administers effectively monitor the public transportation...
In this paper, we propose a video-based metropolitan positioning system (V-MPS) for providing centimeter-grade localization in vehicular networks. The V-MPS system integrates vehicular networks with installed roadside/intersection cameras to provide positioning information to vehicles on the road. V-MPS can estimate the precise position of a vehicle and detect the located lane for each vehicle. To...
Nowadays, interconnected ubiquitous objects are more and more present in different applications as a technical solution to collect, every time and everywhere, great amounts of data which are accessible through the Internet. One interesting area of application is the monitoring of cattle, in order not only to improve the farming working conditions but also to better know the behavior of the animals...
Aspect-oriented programming enables to affect existing code without having to make changes to it. By this, changes remain modularized and as such are easily activated or deactivated with a high potential of direct reusability in other applications. However, aspect-oriented programming on mobile platforms is practically unexploited, despite the whole range of opportunities such as usage monitoring,...
