Effective and efficient management of water resources is becoming unprecedentedly more important nowadays due to the increasing demand from a growing population, increasing standards of living and changing supply due to climate change. Water monitoring technology has directly contributed to the effectiveness of water resource management. Traditional water measurement method, mostly done in laboratory,...
As a critical component of collective motion coordination, decentralized heading alignment is fundamental in systems as diverse as vehicle platoons, mobile sensor networks, swarm robotics, and animal groups. Due to the intertwined interaction between nonlinear continuous-time robot/vehicle dynamics and (possibly) aperiodic discrete-time communication characteristics, a unified design of communication...
This paper presents the effect of pattern slot size on measurement results of a noncontact laser sensor, in which the noncontact laser sensor is used to measure a precision stopping error of a moving object at a specific position, and to send measurement errors to a main control station through ZigBee wireless communication. Measurement accuracies for various vertical slot sizes are tested experimentally...
In this paper we present the design of a mobile system for ethanol leak localization in the environment with wireless transmission to a computer. The system is composed of two operating modules: a communication module that transmits and receives information about the localization in a full-duplex wireless manner through a pair of transceivers, and a motion module that has an ultrasonic displacement...
In this paper, we propose a data forwarding method for efficient data gathering in wireless sensor networks with multiple mobile sinks which freely move in the target region. In our proposed method, each sensor node forwards data packets based on information on connectivity (the status of connection with mobile sinks). As the way to share information on connectivity among neighboring nodes, we integrate...
This paper presents development of an autonomous flying robot (unmanned aerial vehicle) and its verification via flight control experiment. The autonomous flying robot has a global positioning system (GPS) sensor to control its altitude and also a wireless camera to gather visual information from the air. First, we construct a longitudinal model of the autonomous flying robot to design a stable controller...
This paper is following the development of the PhD research of Optimizing Real-Time Applications for Marine Operations Using Modern Modelling and Simulation Methods and presents the major challenges in designing simulation scenarios for offshore exploration constructions models and furthermore, some sensor deployment methods using remote operated vehicles (ROV).
In this paper, we propose a novel data forwarding method for efficient data gathering in wireless sensor networks with multiple mobile sinks which freely move in the target region. In our proposed method, each sensor node recognizes its status of connection with mobile sinks based on the number of received beacons periodically emitted by each mobile sink. In addition, information on that status are...
This paper presents a remote, human-controlled, immersive Unmanned Robotic System (URS) designed to assist in search and rescue operations. The system is being designed and constructed by the Embry-Riddle Aeronautical University Department of Electrical, Computer, Software, and Systems Engineering 2011/2012 Senior Design Team. Described in this paper are two different implementations of the URS -...
The node mobility is a natural element of many wireless sensor and actor network (WSAN) applications. Recent advances in the development of small unmanned aerial vehicles (UAVs) with built in sensors made it possible to deploy aerial sensor and actor networks. An aerial network composed of small UAVs enables high quality observation for events while reducing the number of personnel and the risk for...
The innovation in wireless technology is to support in the areas of Intelligent Transport System (ITS). Wireless technology can be used in Vehicle-to-Vehicle and vehicle-to-infrastructure in transport applications. ZigBee is the key protocol for sensor network applications because of the long battery life, low-cost for installation, eases maintenance and small footprint. ZigBee enables mesh networking...
This paper is devoted to design and implement an intelligent scaled car-like mobile robot that possesses the capability of autonomous driving in an extra-road environment and fully autonomous parking on standard parking lots. The final goal is to design a robotized system that is able to process in real-time large amounts of sensor based data, to choose a collision free drivable trajectory through...

Integration of different technologies potentially provides support to wide variety of applications and systems with vastly varying requirements and characteristics. Vehicle tracking system is one of such applications possible by embedding wireless sensor devices on the vehicles. The most of the state-of the-art technology uses GPS (global positioning system) for tracking vehicles which is very expensive...
Advances in vehicle intelligence technology is enabling the development of systems composed of unmanned vehicles, which are able to interact with devices spread on the environment in order to take decisions related to their movements. Sensor networks represent an area that can profit a lot of this new possibilities, as autonomous vehicles can be used to carry sensor devices, which interacting with...
Autonomous vehicles are used in areas hazardous to humans, with significantly greater utility than the equivalent, manned vehicles. This paper explores the idea of a coordinated team of autonomous vehicles, with applications in cooperative surveillance, mapping unknown areas, disaster management or space exploration. Each vehicle is augmented with a wireless sensor node with movement sensing capabilities...
The use of wireless network signal strength proposed to estimate the relative position between vehicles in a robot formation set. We propose a relative leader-follower model which allows us to use the reception signal strength as control variable for robot stabilization in the formation. Vehicle sensors consist of wheel speed and steering angle, the WiFi data consist of reception signal strength (RSS)...
