The growing use of mobile nodes in manufacturing environments is increasing the Quality Service (QoS) requirements communications infrastructures that support them, as case with Industrial Wireless Sensor Networks (IWSN). Managing networks using Software Defined (SDN) addresses challenge handling multiple sources a satisfactory manner. global vision topology SDN controller has allows logical se...

The 6TiSCH (IPv6 over IEEE802.15.4e time-slotted channel hopping mode) wireless sensor network architecture utilizes control packets to construct formation. These are essential for establishing communication links between nodes and configuring settings. trickle timer algorithm is utilized broadcast the DIO packet. carries information about available parent nodes, which then used form routing tr...

Abstract While the ongoing fourth industrial revolution continues to be a major driver behind wireless communication technologies, some environments are so prohibitive that even state-of-the-art solutions can barely achieve ubiquitous connectivity (if at all). For example, in sites with large metal constructions (such as petrochemical plants), highly localized and time-varying changes link qual...

HAL is a multidisciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not. The documents may come from teaching and research institutions in France or abroad, or from public or private research centers. L'archive ouverte pluridisciplinaire HAL, est destinée au dépôt età la diffusion de documents scientifiques de niveau r...

The Internet of Things (IoT) has become ubiquitous due to its flexibility, ease-of-use, and reduced cost. As a consequence, the industry is adopting these systems in transformation into Industry 4.0. However, strict Quality Service (QoS) requirements are not met with default best-effort provisions IoT. Most industrial applications require guarantees terms end-to-end network reliability latency....

This paper studies the e®ect of technology spillovers on the entry decision of a multinational enterprise into a foreign market. Two alternative entry modes for a foreign direct investment are considered: Green ̄eld investment versus acquisition. We ̄nd that with quantity competition a spillover makes acquisitions less attractive, while with price competition acquisitions become more attractive....

Video transmission combines large quantities of data with real-time requirements, two constraints which are hard to meet in low-power wireless multi-hop networks. This position paper presents experimental results of multi-hop video transmission in an IEEE802.15.4-based wireless network, using a protocol stack based solely on standards which are being finalized. This practical look allows us to ...

We thank Jigar Patel and colleagues for their comments. The mean duration of symptoms at enrolment was 5·77 days (SD 3·49) in the azithromycin group 6·27 (3·55) standard care group. 19 (13%) 147 participants 21 (14%) 148 had more than 10 randomisation. Most COVID-19-related deaths occur due to sudden, late respiratory decompensation, peaking day 14 after symptom onset.1Ruan Q Yang K Wang W Jian...

-Conservation plans for amphibians often focus on activities at the breeding site, but for species that use temstrial habitats for much of the year, an understanding of nonbreeding habitat use is also essential. We used radio telemetry to study the postbreeding movements of individuals of the only known population of dark gopher frogs, Rana sevosa, during two breeding seasons (1994 and 1996). M...
