The increasing number of vehicles on the road along with mismanagement available parking space leads to related problems as well increased traffic congestion in urban areas. Thus it is highly required develop an automated smart management system that would help driver find out some suitable for his/her vehicle very quickly. Although ample amount research works development exist literature, but most them have not addressed problem real-time detection improper and automatic collection charges....
LaTe3 is a non-centrosymmetric material with time reversal symmetry, where the charge density wave hosted by Te bilayers. Here, we show that hosts Kramers nodal line-a twofold degenerate line connecting reversal-invariant momenta. We use angle-resolved photoemission spectroscopy, functional theory an experimentally reported modulated structure, effective band structures calculated unfolding, and symmetry arguments to reveal line. Furthermore, calculations confirm imposes gapless crossings...
Traffic congestion is one of the major issues with public transportation system in recent time. The traffic has a negative impact on productivity, competitiveness and economic growth country. Hence control become an important area research significant number solutions to this problem came out various efforts said field over past few decades. Among these, vehicle-to-vehicle (V2V) communication based approaches cannot accurately estimate density congestion. On other hand, signaling systems...

Smart city is an emerging concept that aims to improve the quality of life, enhance efficiency urban operations and services as well create a sustainable economic growth city. Internet-of-Things (IoT) big data have emerged key enabling technologies for smart infrastructure. A major issue in design provision Internet connectivity anywhere within cities through some suitable network Although use cases various business models delivering been proposed literature over past few years, none them...
Location estimation is essential to the success of location based services. Since GPS does not work well in indoor and urban areas, several localization systems have been proposed literature. Among these, fingerprinting-based involving two phases: training phase positioning phase, are used mostly. In a radio map constructed by collecting received signal strength (RSS) measurements at set known locations. whose corresponding RSS pattern matches best with currently observed selected as...
Underwater acoustic sensor network (UASN), which is a of wireless nodes distributed over certain area within the underwater environment and communicating via signal, can act as an assisting technology for variety applications including earthquake tsunami forewarning, naval surveillance, marine biology etc. As GPS signal highly absorbed water, whereas radio attenuates more optical scatters while they try to propagate environment, preferred communication between nodes. In spite data centric...
Several methodologies on the provisioning of Location-Based Services (LBSs) solely using GPS-based positioning or combining several techniques like GPS, GSM Cell-ID, Wi-Fi, Bluetooth and RFID etc. have been proposed over past few years. Most these systems do not focus limited battery power, memory-constraint mobile devices, heterogeneity platform proper authentication checks before providing LBSs to user. Our system utilizes low-cost, low-power wireless technology as indoor technique...
Abstract The rapid growth of mobile communication and pervasive computing technology has expanded the demand for location-based services in urban areas, which necessitate accurate localization tracking user. Due to very poor performances global positioning system (GPS) indoor areas canyons, various radio frequency (RF) technologies have been exploited by many researchers design systems (IPSs) over years. However, such RF based IPSs would work only presence certain infrastructure. emergence...
Smartphone sensor-based pedestrian dead reckoning (PDR) systems provide a viable solution to the problem of localization in an infrastructure-less area. Step detection (SD) and step length estimation (SLE), being two fundamental operations PDR-based technique, have drawn many researchers' attention recent time. Most existing SD SLE methods proposed over years, however, either server-or cloud-based that consume additional network bandwidth suffer from increased transmission delay. Moreover,...
Among the various indoor localization systems, received signal strength (RSS) based fingerprinting provides most cost-effective solution as it uses existing wireless network infrastructure. The positioning accuracy of such systems can be improved by incorporating huge number training data, which in turn, increases searching overhead systems. Several clustering strategies for have been proposed literature order to reduce overhead. On other hand, placement strategy beacon nodes within field...
With immeasurably increasing number of vehicles on the road day by day, deadly accidents that cause significant loss lives, is also increasing. So, various researchers have paid attention in development some safety application or accident avoidance system order to minimize such fatalities. Among existing applications, image-processing based techniques can perform well only if vehicle line-of-sight with camera and their performances sufficiently worsen hearse weather conditions like dense...
A lot of wireless localization schemes using time arrival (TOA) have been proposed in the literature with comprehensive performance comparisons terms accuracy, complexity and robustness. The major issue TOA-based is that presence error due to non-line-of-site (NLOS) propagation range measurements introduces a errors location estimation. Thus we focused on those can mitigate effect NLOS provide reasonable accuracy. Another computational incurred by solving non-linear equations associated...
5G positioning is an essential part of many applications, such as driverless vehicles, drone tracking, emergency services, location-based etc. Such can attain accuracy on the order 1 meter or even lower in both indoor and outdoor settings due to its several advantageous aspects, which include millimeter wave signal, multiple input output antennas, device-to-device communication, Hence, researchers have paid attention development systems over past decade.
