Radio frequency identification system (RFID) is an automatic technology and aids machines or computers to identify objects, record metadata control individual target through radio waves. Connecting RFID reader the terminal of Internet, readers can identify, track monitor objects attached with tags globally, automatically, in real time, if needed. This so-called Internet Things (IoT). often seen as a prerequisite for IoT. paper introduces technologies IoT, discusses applications challenges used
Abstract A Low Earth Orbit (LEO) constellation augmenting satellite navigation is important in the future development of Global Navigation Satellite System (GNSS). GNSS augmented by LEO constellations can improve not only accuracy Positioning, Navigation, and Timing (PNT), but also consistency reliability secure PNT system. This paper mainly analyzes diverse demands different users for GNSS, including precision demand real-time, availability special areas, signal enhancement complex...
In this paper, an efficient anti-collision protocol, named collision tree protocol (CT), is proposed, and a put forward to capture the complete communications between reader tags in execution of CT. The main novelty CT that both generating prefixes splitting tag group are according collided bit directly. Both properties results experiments show proposed improves efficiency identification up 50% achieves best performance tree-based protocols.
A stable and efficient anti-collision protocol is very important for tags identification in many radio frequency (RFID) system such as flow productions automatic controls. In this paper, we introduce an named collision tree (CT) analyze the stability of it detail. Both theoretical results experimental indicate that performance CT only dependent on number to be identified not influenced by distribution tag IDs other factors, average one-tag converges a constant. According definition protocol,...
The quality of the dissertations for Master Fine Arts professional degree not only reflects academic proficiency and research capacity graduate students but also embodies teaching reputation training institutions. This is based on data from China National Knowledge Infrastructure (CNKI) at X University. Through analyzing quantity dissertations, distribution publication years, download frequency citation frequency, in combination with in-depth literature reading, main factors influencing are...
Intensification of urban construction has gradually destroyed human habitat ecosystems. Plants, which serve as the foundation ecosystems, require green, low-cost, and effective technologies to sustain their growth in stressful environments. A total 286 keywords 10 clusters from bibliometric analysis 529 articles (1999–2023) indicate increasing importance research on microbial functionality landscape Phosphate solubilizing microorganisms (PSMs) also improve plant disease resistance,...
Abstract To provide competitive global positioning and timing services under the condition that monitoring stations are confined to Chinese territory, inter-satellite link (ISL) technology is used by third-generation BeiDou Navigation Satellite System (BDS-3). The ISL, together with dual one-way links between satellites anchor stations, may enable autonomous navigation for BDS-3. In this paper, we propose a general observation model orbit determination (OD) time synchronization (TS) directly...
Traditional anti-collision protocols for RFID tags identification assume that the and reader are stationary, i.e., no tag is coming in or leaving during identification. If not, cannot ensure all identified. However, mobile system, of them moving continuously, dynamically enter leave reading area. Therefore, traditional not suitable system. This letter presents a dynamic protocol, called collision tree to be used system identify move into
The basic system of the BeiDou global navigation satellite (BDS-3) with 18 satellites has been deployed since December 2018. As primary frequency standard, BDS-3 include two clock types passive hydrogen maser (PHM) and rubidium atomic standard (RAFS). Based on final precise orbit product from Xi’an Research Institute Surveying Mapping (XRS), performance is evaluated, including accuracy, drift rate, stability, compared GPS block IIF RAFS, Galileo PHM, BDS-2 satellites. A data auto-editing...
Abstract There is increasing concern about the uncombined (UC) observation model in field of global navigation satellite system (GNSS). Based on positioning (GPS) and third-generation BeiDou (BDS-3), this study processed UC precision orbit determination (POD) for single dual systems. First, a suitable multi-GNSS POD was derived, ionospheric-free (IF) combination presented. Although ambiguity parameters IF strategies were different after reparameterization, difference could be removed when...
Summary Many anti‐collision protocols have been proposed at present. Almost all known exhibit an overall identification efficiency smaller than 50%. And of them are for general purpose applications and do not consider the distribution characteristic tag IDs in different radio frequency (RFID) systems. In real world, there many RFID systems, which mostly distributed continuously, such as container terminals, warehouse management, supply chain so on. This paper presents efficient protocol,...
