Analysis of an IoT-Based SDN Smart Health Monitoring System

Abstract: Health specialists and scientists advocated for the use of IoT-based remote health monitoring devices to track the health of the senior citizens and critically challenged patients. However, such technologies may generate massive amounts of data, necessitating the security and privacy of that data. Various health monitoring system's (HMS) safety and privacy issues propose the management of a safety IoT-based health monitoring system, privacy, and dependable service delivery to patients and seniors to minimize and avoid health risk. High quality of life is dependent on good health. A continuous health care monitoring system is required for healthcare, and the data is stored in the cloud via a network, allowing doctors and nurses to provide patients with rapid treatment. IoT is the most recent developing technology for healthcare that is associated with electronic devices such as sensors and smart phones that have become part of everyday life. Sensors and wireless sensor networks (WSN) are used by the Internet of Things to interact with patients to recognize medical concerns and communicate with them. Sensors collect a vast amount of data that is physically linked to the patient. Integrate data in the cloud with the aid of Software Defined Networks (SDNs). SDN keeps track of sensitive information and ensures the safety of medical records. It will assist not just patients but also health care professionals in safeguarding particular patient data. SDN not only secures data but also prevents traffic from flowing from source to destination. This study intends to build a smart health care system with SDN by utilizing an IoT application to collect data via sensors and then stores it in the cloud.

Empirical View Of Financial Management Survey In Block Chain Technology Issues, Risk And Mitigation

Abstract: A blockchain is simply a shared database of information or public ledger of all completed and shared transactions or digital activities between cooperating occurrences. Each transaction in the public ledger is confirmed by a majority of the participants within the device. Data cannot be removed once it has been input. The blockchain is a secure and verifiable record of every single transaction ever made. The most popular example of blockchain generation is Bitcoin, a decentralize dpeertopeer digital currency. Although the virtual foreign currency bitcoin is debatable, the blockchain technology that underpins it has performed admirably. The main hypothesis is that the blockchain creates a system for reaching a distributed consensus in the virtual online world. By developing an irrefutable file in a public ledger, participating entities may be certain that avirtual event occurred. It paves the way for the development of a democratic, open, and scalable digital economy from a centralised one. This disruptive period offers incredible prospects, and the change in this field has only just begun. The blockchain age is described in this white paper, as well as some intriguing specific applications in the monetary and nonfinancial sectors. We then research the difficulties ahead of time as well as the commercial opportunities in this critical age.

Efficient Energy Attentive and Fault Recognition Mechanism in Distributed Wireless Sensor Networks: A Review

Abstract: A recent modernization in wireless sensor networks (WSNs) has played a remarkable role to track and control the physical world. This technology is exhilarating with countless potential for many enormous applications like biomedical, industry, defence and so on. Despite of their benefits, design of energy attentive and fault recognition steering protocol is a key challenge. Plenty of research works has been proposed in past by many researchers based on multipath, query and location aware sensor network. However still there is a scope for enhancement in the performance of sensor network by finding efficient energy aware solution. Comprehensive analysis of existing methodologies in view of two challenges, energy management and fault recognition mechanism for scalable network is the main objective of this paper. This broad survey helps researchers to aware about technical concern and challenges in energy efficient fault recognition mechanism for WSNs.

Framework for effective utilization of e-content in engineering education

Abstract: Even though lot of useful content is available on the Internet that is relevant to engineering courses, the scattered nature of the content being available from different websites, wastage of time in finding the right content, absence of any mechanism that certifies the correctness of the accessed content, different levels of the content on a given topic, too-lengthy non-interactive text content, are some of the problems faced by learners, in using this available content. In this context it is important to have a system that can direct the learner to right content, which is presented in an easily understandable manner, with virtual experimentation options wherever applicable, along with appropriate assessments carried out to certify the assessed. In this backdrop, a framework is proposed in this paper that can offer the details of e-content, in terms of its type, relevance, level, correctness, extent of coverage, and usage statistics. By making this info available from authenticated portals like University websites, updating it frequently by sharing information from similar other portals, taking into account the user feedbacks and subject experts' ratings to decide the content quality, learners can be enabled to access good quality e-content in less time and effort. Software agents similar to citation agents are proposed to be used for collecting the details from multiple sites in Internet. For assessment also, the software clients that run on content pages can bring the result of such assessments to the portals where the data belonging to such other previous assessments taken by the user were also stored to offer assessment scores of the learner over a period of time on multiple subjects and skills. Overall, this system can reduce the burden of the learner in accessing the required content and can make his learning more interesting by having competitive learning with online assessments and credits obtained thereon.
