Along with energy, finance, governance, etc., the healthcare sector is one of the most prominent areas where blockchain technology is being used. We all are aware that data constitute our wealth and our currency; vulnerability and security become even more significant and a vital point of concern for healthcare. Recent cyberattacks have raised the questions of planning, requirement, and implementation to develop more cyber-secure models. This paper is based on a blockchain that classifies network participants into clusters and preserves a single copy of the blockchain for every cluster. The paper introduces a novel blockchain mechanism for secure healthcare sector data management, which reduces the communicational and computational overhead costs compared to the existing bitcoi...

Implementing a better high-quality real-time system requires to improve the responsiveness of the tasks set. This research work aims to achieve the best quality of service (QoS) in terms of improving the responsiveness of aperiodic tasks and also improved acceptability domain, by accepting to execute multiple aperiodic functions while maintaining the feasibility of periodic tasks in a real-time system.The functional analysis with simulation shows that the proposed algorithm is highly effective in terms of task sets deemed schedulable and also by allowing aperiodic tasks that were rejected by existing approaches. The simulation results indicate that it reduces overall average response time of aperiodic tasks approximately 13% at lowest periodic load (35%), 7% at 60% periodic load, and 4% at 80% periodic load, and in all observed circumstances, the proposed novel algorithm received 7%-10% improv...

With medicine being of such great importance, it is necessary for one to take his doses on time. But older people and virus-infected people find it difficult to remember their medicine schedule. To overcome this problem, this proposed work “Smart Medicine Dispenser” stores their daily medicine schedule and notifies them on the basis of the schedule about when and which medicine to take. Using Wi-Fi, it can also notify the caretaker of the patient about whether the patient has taken his medicine or not. It comprises a box containing several small sections in which we can store medicines according to their daily dose. It uses a real-time clock (RTC) module and an alarm system to make sure that the patient takes his dose on time. The experimental results show that the proposed model gives better results in comparison with existing work.

Nevertheless, the performance of the system-on-chip (SoC) is incredibly influenced by the performance of the network hidden on a chip named network-on-chip (NoC). Routing of network-on-chip network chips plays a crucial role in the overall performance of the NoC. In this paper, we have proposed a routing algorithm that utilizes the neural network to perform the routing. This routing algorithm updates the route dependent on the port execution of the switch. From the outcome, the execution of the directing has worked successfully and has the option to deal with the enormous burden viably. The result obtained shows that the performance metric for the uniform traffic is slightly better in comparison to XY routing at the higher loads of 80%. In the case of neighbor traffic, bit complement traffic, and tornado traffic, these values are higher on 80% of the load. The reason for better...

Many of the population around 75% depends on agriculture. Therefore, it is needed to use best out of it. In the modern era of agricultural system, India lag behind from other countries. Still there are the things to be taken care of for the increase in agricultural production and efficiency. Many countries have adopted precision based agriculture system. The agricultural system in India still need to modernize for the better production and dispersal of crops. In this paper the authors have proposed a Multidisciplinary model for smart agriculture using many technologies like IoT, Big data, Cloud Computing, Machine Learning, Wireless Sensing Network, Sensors, Mobile Computing. The IoT will run parallel with these technologies for precision based model. The model sets up in a way that it will collect the data produced by various sensors like rain sensor, temperature sensor, humidity sensor, soil and moisture sensor. These data will be analyzed and the relevant information has been sent to farmers and agro vendors like weather conditions, temperature. The farmers will take action accordingly. This real time based application will increase their productivity and decrease the effective cost and time.

In those spaces multiplex guests don't buy from their first visit and not all guests find their choice by just visiting. We propose in this paper a smart guest counter for the shopping centers and mass-market spaces. We will have four rudimentary tracks in fetching and analyzing APC statistics which is ordinary to all APC's. Those are information-accession, Statistics-recording and store, Information-fetching to processing and scrutiny. This method operates on the basis of tackle and software members. Counting detectors at each entry, for starters, dredge person exertion. Information retrieval machine on board take accounts of entries and exits using a logic computation. Usually, such entries and exits are kept in a fashion that gives smooth counting stop-referencing. It is accomplished by keeping track of time as well as distance measurements. The information is then redirected from the on-board storage device to a central computing installation using some kind of ministry. Finally, the info is entered into computer programs, and the requested info is presented.

So for resolving this issue we are proposes a real time application controlled door locking/unlocking mechanism which harnesses the power of IOT and machine learning for smooth functionality. The door unlocking system proposed here uses a Raspberry Pi 3 model B for computation along with a Pi Camera to take face as an input of the user. Also in order to make door unlocking fail proof, fingerprint sensor is used. Scenarios like bad lighting and camera failure can be easily dealt using this sensor. The face detection and recognition system used for door opening will be able to learn user’s faces from time to time and update its dataset. So any subtle changes in the face of user like addition of spectacles or removal of beard can be easily dealt with.

Currently we have a manual system where the street lights will be switched ON in the evening before the sunsets and they are switched OFF in the next day morning after there is sufficient light outside and currently there is no such system in India that helps in monitoring or detecting collisions occurred on roads. This we can implement by sensing a vehicle using an Ultrasonic sensor/IR sensor and using some heat & sound sensors for sensing the collision if it occurs. On sensing the movement of a vehicle, the sensor transmits the data to the Raspberry Pi, which will switch ON the next three consecutive street lights in order to give the driver a visible track to drive in dark. Similarly, the Light gets switched OFF according to a timer that gets triggered as soon as the vehicle or an obstacle goes away from the sensor
