navigation
Opis:: In wireless mobile sensor networks, periodic calculation of coverage is very important, since mobile sensors can be moved adequately to current needs, thus increasing the coverage. Those moves require the execution of navigation tasks. Global network central algorithms for those tasks are very costly regarding energy consumption and computational resources. Considerations presented herein pertain to the best algorithms for a network of numerous small mobile sensor nodes used for monitoring of large terrains. Localized algorithms suggested in this paper help calculate the coverage on-line and locally with the involvement of neighboring nodes only. Furthermore, localized collaborative navigation is presented. It enables yielding position estimation with no GPS use and ensures improvement rather than deterioration over time. It uses multi-sensor fusion algorithms based on optimization and a distributed iterative extended Kalman Filter.

Opis:: In Poland and in the world is conducted air monitoring in order to care for the atmospheric air. Thus, it is possible to develop of appropriate plans of improvement air quality in certain areas. Unfortunately, the number of stationary equipment in large cities is usually insufficient. For example, in Warsaw under the State Environmental Monitoring, information on the concentrations of pollutants in the air provide only 8 automatic stations and 3 manual stations, of which only 5 stations belong to the Mazovia Voivodship Inspectorate for Environmental Protection. 11 monitoring stations in the metropolitan area of 517 km2, is the number that is not able to provide an accurate measurement of air quality. In the article, on the example of Warsaw, is presented the concept of mobile network devices for air monitoring, from which data could complement to those from the fixed stations. The article sets out the measured substances, estimated cost of mobile network devices, and the choice of means of transport to move measuring devices.

Opis:: This paper presents an idea of wirelessly powered mobile sensors utilizing cloud management system similar to the swarm robotics. Sensors are based on the previously developed wireless passive sensors working with RFID protocol in the HF range. Preliminary research presented in this paper is related to the energy harvesting efficiency evaluation and the possibility to wirelessly power an electric motor. Performed experiments show that the magnetic field generated by the RFID reader antenna provides enough amount of energy not only to perform communication, measurements and computation, but to power the actuators as well. Achieved results state a base for further investigation in the area of wireless passive mobile sensors.
W pracy zaprezentowano koncepcję zasilanego bezprzewodowo czujnika mobilnego wykorzystującego system zarządzania w chmurze, podobny do stosowanego w zarządzaniu rojem robotów. Projekt czujnika został oparty na opracowanych wcześniej bezprzewodowych czujnikach pasywnych opartych na technice RFID, pracujących w zakresie wysokich częstotliwości HF (z ang. High Frequency). Pierwsze doświadczenia, zaprezentowane w publikacji, odnoszą się do oceny efektywności możliwości pozyskiwania energii z sygnału emitowanego przez czytnik RFID oraz sprawdzenia możliwości bezprzewodowego zasilania silnika elektrycznego. Wykonane eksperymenty pokazują, że pole magnetyczne wytworzone przez antenę czytnika RFID, dostarcza wystarczającą ilość energii nie tylko do komunikacji pomiędzy czytnikiem a czujnikiem, pomiarów i obliczeń, ale również do zasilania aktuatorów. Zaprezentowane wyniki stanowią bazę dla dalszych doświadczeń w zakresie bezprzewodowych pasywnych czujników mobilnych.

Opis:: This paper aims at designing, building, and simulating a secured routing protocol to defend against packet dropping attacks in mobile WSNs (MWSNs). This research addresses the gap in the literature by proposing Configurable Secured Adaptive Routing Protocol (CSARP). CSARP has four levels of protection to allow suitability for different types of network applications. The protocol allows the network admin to configure the required protection level and the ratio of cluster heads to all nodes. The protocol has an adaptive feature, which allows for better protection and preventing the spread of the threats in the network. The conducted CSARP simulations with different conditions showed the ability of CSARP to identify all malicious nodes and remove them from the network. CSARP provided more than 99.97% packets delivery rate with 0% data packet loss in the existence of 3 malicious nodes in comparison with 3.17% data packet loss without using CSARP. When compared with LEACH, CSARP showed an improvement in extending the lifetime of the network by up to 39.5%. The proposed protocol has proven to be better than the available security solutions in terms of configurability, adaptability, optimization for MWSNs, energy consumption optimization, and the suitability for different MWSNs applications and conditions.

Opis:: Travel time estimation for freeways has attracted much attention from researchers and traffic management departments. Because of various uncertain factors, travel time on a freeway is stochastic. To obtain travel time estimates for a freeway accurately, this paper proposes two traffic sensor location models that consider minimizing the error of travel time estimation and maximizing the collected traffic flow. First, a dynamic optimal location model of the mobile sensor is proposed under the assumption that there are no traffic sensors on a freeway. Next, a dynamic optimal combinatorial model of adding mobile sensors taking account of fixed sensors on a freeway is presented. It should be pointed out that the technology of data fusion will be adopted to tackle the collected data from multiple sensors in the second optimization model. Then, a simulated annealing algorithm is established to find the solutions of the proposed two optimization models. Numerical examples demonstrate that dynamic optimization of mobile sensor locations for the estimation of travel times on a freeway is more accurate than the conventional location model.

Opis:: Road surface temperature and road longitudinal temperature gradient value, may present a considerable challenge in the matter of traffic safety. The awareness of thermal conditions with due regard to location of significant temperature variability areas could be desirable information for road infrastructure operators. That knowledge would allow to select an appropriate location of traffic signs, variable message signs and road weather stations. In the wintertime it would enable road maintenance authorities to take more efficient actions. In the study authors present road surface temperature variability analysis based on measurements conducted on a 6.25-kilometer section of eastern bypass of Bielsko-Biala city. In analysis authors used the data from mobile road weather sensor. The sensor enables to measure road surface and dew point temperature, water film height and calculated friction.

Due to the circumstances of such an environment we cannot rely on any data from GPS, Wi-Fi or RFID. Moreover this work should serve us as a first step towards an all-in-one navigation system for mobile devices. Our experimental results show that we can achieve high accuracy in position estimation.

Opis:: The paper presents a set of soŌware tools dedicated to support mobile robot navigaƟon. The tools are used to process an image from a depth sensor. They are implemented in ROS framework and they are compaƟble with standard ROS navigaƟon packages. The soŌware is released with an open source licence. First of the tools converts a 3D depth image to a 2D scan in polar coordinates. It provides projecƟon of the obstacles, removes the ground plane from the image and compensates sensor Ɵlt angle. The node is faster than the standard node within ROS and it has addiƟonal funcƟons increasing range of possible applicaƟons. The second tool allows detecƟon of negaƟve obstacles i.e. located below the ground plane level. The third tool esƟmates height and orientaƟon of the sensor with RANSAC algorithm applied to the depth image. The paper presents also the results of usage of the tools with mobile plaƞorms equipped with MicrosoŌ Kinect sensors. The plaƞorms are elements of the ReMeDi project within which the soŌware was developed.

Opis:: Basic gesture sensors can play a significant role as input units in mobile smart devices. However, they have to handle a wide variety of gestures while preserving the advantages of basic sensors. In this paper a user-determined approach to the design of a sparse optical gesture sensor is proposed. The statistical research on a study group of individuals includes the measurement of user-related parameters like the speed of a performed swipe (dynamic gesture) and the morphology of fingers. The obtained results, as well as other a priori requirements for an optical gesture sensor were further used in the design process. Several properties were examined using simulations or experimental verification. It was shown that the designed optical gesture sensor provides accurate localization of fingers, and recognizes a set of static and dynamic hand gestures using a relatively low level of power consumption.

Quantitative errors in range measurement are evaluated considering the intensity output available from the sensor. The obtained intensity values help to correct the range measurements with regard to the optical characteristics of the observed surfaces. Moreover, mixed measurements are characterized and compared to the mixed measurements characteristics in the popular Sick LMS 200 laser scanner. Finally, it is shown how taking into account the error characteristics of the URG-04LX scanner improves its performance as the main exteroceptive sensor of a small walking robot.
