This paper deals with load management in flexible industrial networks, characterized by a hybrid wired/wireless architecture and mobile wireless nodes. Our target scenario is an industrial network, in which data is exchanged between sensors and actuators running on the wireless side and a wired automation network. As many unpredictable elements affect the performance of wireless data transmission, it is necessary to control the load over the different Access Points (AP) through dynamic balancing policies. In traditional WLANs, one station selects the AP to connect with on the basis of the received signal strength indicator (RSSI). This approach may cause all active mobile stations to connect to a small subset of the APs and saturate their capacity, while other APs may still be underloaded. This paper shows a dynamic technique to manage the unbalanced load caused by moving nodes and fluctuating channel characteristics. Simulation results highlight the advantage of the proposed technique over the standard AP selection mechanism and another load balancing approach in the literature.

Quality control of food products, including beverages, during the production process is an important task that can be successfully solved by information technology. Currently, quality control of wine, beer, juices and other beverages is carried out using biochemical control, which takes a time and requires the application of complex analytical devices under the control of qualified personnel. The development of information technologies, biosensors, sensor networks makes it possible to solve the problem of quality control of various beverages in express mode. The main contribution of this paper is the design and prototyping of wireless amperometric biosensors and wireless sensor network (WSN) on their base to monitor the concentration of various components in beverages. The WSN architecture was modified for technological process of winemaking. Wireless biosensors were tested with different types of enzymes on different concentration of solutions. Such tests confirm the possibility to use the wireless biosensors on some stages of technological process of winemaking. The upgrading wireless nodes by sensing unit with particular enzymes will allow covering all technological process.

IEEE International conference on ATM

作者： K. Toyoshima K. Hayashi NTT Optical Network Systems Laboratories Yokosuka Japan

The number of Internet users continues to increase due to the popularity of the WWW (World Wide Web). Intranets and extranets have also become very popular as they enable the efficient use of data within companies and enhance business processing speed. IP (Internet protocol) packets are used to realize most of these computer communication services. IP belongs to the network layer in the OSI reference model, so the transfer performance of IP is influenced by the technology used in the data link layer under the network layer. One communication technology for the data link layer is ATM (asynchronous transfer mode). ATM technology was researched and recommended for B-ISDN (broadband integrated services digital network). We have been tackling an Internet/intranet/extranet backbone system that offers high speed, high throughput, small delay and low cost by IP/MAC (media access control) over ATM. However we faced the problem that ATM does not completely suit IP packet and MAC frame transfer. For example, there is the "dead cell problem" in which the loss of even one of the ATM cells forming the IP packet causes the loss of the entire packet. There is also the "cell tax problem", in which the overhead of ATM cells is much larger than those of other long distance transfer techniques. Perfect EPD (early packet discard) is impossible because there is no indication bit that means a cell includes the head or tail part of a datagram in the payload. Moreover, intelligent and effective application use is difficult because the cell header has few CLP (cell loss priority) bits. This paper describes the main problems of datagram transfer across existing ATM networks and details a new cell structure that solves these problems. Other issues relating to this remodelling of the existing cell structure are also examined.

One of the most effective way to prevent unauthorized and corrupted message being forwarded in wireless sensor network. But there is high computational and communication overhead in addition to lack of scalability and resilience to node compromise attacks. So to address these issues, a polynomial-based scheme was recently introduced. However, this scheme and its extensions all have the weakness of a built-in threshold determined by the degree of the polynomial. when the number of messages transmitted is larger than this threshold, the adversary can fully recover the polynomial. In the existing system, an unconditionally secure and efficient source anonymous message authentication (SAMA) scheme is presented which is based on the optimal modified Elgamal signature (MES) scheme on elliptic curves. This MES scheme is secure against adaptive chosen-message attacks in the random oracle model. This scheme enables the intermediate nodes to authenticate the message so that all corrupted message can be detected and dropped to conserve the sensor power. While achieving compromise resiliency, flexible-time authentication and source identity protection, this scheme does not have the threshold problem. While enabling intermediate nodes authentication, this scheme allows any node to transmit an unlimited number of messages without suffering the threshold problem. But by using this method the black hole and gray hole attacks are detected but wormhole attack is doesn't detect. Because the wormhole attack is one of the harmful attacks which degrade the network performance. So, in the proposed system, one innovative technique is introduced which is called an efficient wormhole detection mechanism in the wireless sensor networks. In this method, considers the RTT between two successive nodes and those nodes' neighbor number which is needed to compare those values of other successive nodes. The identification of wormhole attacks is based on the two faces. The first consideration is that

Driven by the vision of ubiquitous connectivity and wireless intelligence, the evolution of ultra-dense constellation-based satellite-integrated Internet is underway, now taking preliminary shape. Nevertheless, the entrenched institutional silos and limited, nonrenewable heterogeneous network resources leave current satellite systems struggling to accommodate the escalating demands of next-generation intelligent applications. In this context, the distributed satellite information networks (DSIN), exemplified by the cohesive clustered satellites (CCS) system, have emerged as an innovative architecture, bridging information gaps across diverse satellite systems, such as communication, navigation, and remote sensing, and establishing a unified, open information network paradigm to support resilient space information services. This survey first provides a profound discussion about innovative network architectures of DSIN, encompassing distributed regenerative satellite network architecture, distributed satellite computing network architecture, and reconfigurable satellite formation flying, to enable flexible and scalable communication, computing and control, fundamentally enhancing network resilience. The DSIN faces challenges from network heterogeneity, unpredictable channel dynamics, sparse resources, and decentralized collaboration frameworks. To address these issues, a series of enabling technologies is identified, including channel modeling and estimation, cloud-native distributed MIMO cooperation, new waveform design, grant-free massive access, non-orthogonal multicast, distributed phased array antennas, high-speed inter-satellite communication, network routing, and the proper combination of all these diversity techniques. Furthermore, to heighten the overall resource efficiency, the cross-layer optimization techniques are further developed to meet upper-layer deterministic, adaptive and secure information services requirements. In addition, emerging research dire

When migrating a service from a legacy system to a target platform, the tasks associated to the introduction of the new platform should be distinguished from the subscriber data migration itself. Migrating the subscriber data of a Prepaid service is a complex operation because data at Application level is checked in real-time when the service is triggered, and further influences the actual behaviour of the service delivered to the end-subscriber. In most cases, telcos want to avoid service interruption for end-subscribers. But the migration steps take some time, so there is always a delay between the moment when subscriber data is dumped from the legacy system and the moment when it can be actually uploaded onto the target platform. Consequently, updates during migration windows cannot be taken into account. In order to avoid any credit loss for the end-subscribers, recharges should be blocked in that time frame. Besides, the routing of the calls and the subscriber location information need to be updated in the customer environment too. A detailed migration procedure involving all the steps on the legacy system, on the target platform, and on the Core network needs to be designed. Two examples of successful Prepaid Migration are given, one at KPNMobile, one at Vodafone. In the context of the IMS architecture, the current issues with Migration could eventually be simplified in the future.

Natural disasters are a growing issue these days. Vehicle, rail, and truck air pollution can cause respiratory diseases and asthma episodes. Transportation accounts for more than half of all carbon monoxide emissions in the atmosphere. Currently, when the RTO office issues the wellness certification, the vehicle's emissions are validated using pollution control stations located in particular urban areas. The health declarations for private autos are valid for a long time and must be updated at regular intervals after that. In the case of transportation vehicles, the health certification is granted for a long time and then expanded every year. We cannot distinguish outflows caused by this interaction since we presume the vehicle is static until FC. This project will be able to monitor and warn about air pollution on city streets by linking the Global System of Mobile communications network to the cloud, as well as track automobiles that emit discharges above a set edge. This also focuses on avoiding accidents caused by carbon monoxide gas produced by vehicles by installing a Gas sensor.

The novel Coronavirus has really been the unexpected Catastrophe, which no one could have even thought of. It has emerged as a pandemic and has raised questions on the health infrastructure and facilities available as it is required to get a large number of people tested. RT-PCR is the standard diagnostic test being used. But there are several issues with RT-PCR testing like relying only on one approach even when it is getting difficult for most countries to procure the required amount of testing kits, also there have been some cases of false positive results. all these factors definitely call for a search of alternative testing methodologies, so it not reqired to rely on just one approach. Apart from RT-PCR testing, Chest X-rays can be a great tool to know about the status and severity of COVID-19. Once obtaining the chest X-rays of a person a call has to be made on the COVID-19 status and that needs very high accuracy and expertise and again there will be a shortage of the expertise. So, a solution has been proposed to this problem by developing a COVID-19 detection system, which can assist the medical experts regarding the report and then the experts can make a final call. As observed, DeepLearning techniques, especially Convolutional Neural network (CNN) have proven to be outstanding in medical image classification and analysis, and as our task is similar to medical image classification, CNN is a good choice for our use case. So, we analyzed four different CNN architectures on Chest X-ray for Covid-19 Diagnosis. The models used are pretrained on ImageNet datasets. Transfer Learning has been used to generate results. A comparative study of the results obtained with different architecture reveals that structures based on CNN have great potential for Covid-19 diagnosis and detection.

IEEE Annual Joint conference: INFOCOM, IEEE Computer and communications Societies

Wavelength band switching (WBS) has only recently attracted attention from the optical networking industry for its practical importance in reducing the control complexity and cost of optical cross-connects (OXCs). However, WBS-related problems of theoretical interest have not been addressed thoroughly by the research community, and many issues are still wide open. In particular, WBS is different from wavelength routing, and thus techniques developed for wavelength-routed networks (including e.g., those for traffic grooming) cannot be directly applied to effectively address WBS-related problems. In this paper, we first propose a new multigranular OXC (MG-OXC) architecture for WBS, which is more flexible than any existing WBS node architectures. We also adopt the most powerful waveband assignment strategy, and develop an efficient heuristic algorithm called Balanced Path routing with Heavy-Traffic first (BPHT). To verify its near-optimality, we also develop an integer linear programming (ILP) model. Both the ILP and the BPHT algorithms can handle the case with multiple fibers per link and hence are more general than our previous single-fiber solutions X. Cao et al. (2002). We conduct a comprehensive evaluation of the benefits of WBS through detailed analysis and simulations. We show that the proposed heuristic BPHT can perform much better than a heuristic which applies the optimal routing and wavelength assignment (RWA) method. We also show that WBS using BPHT is even more beneficial in multifiber networks than in single-fiber networks in terms of reducing the port count. Our analytical and simulation results also provide valuable insights into the effect of wavelength band granularity, as well as the trade-offs between the wavelength-hop and the port count required in WBS networks.
