The scheme is difficult to expand and has little concurrent ability, so it is not suitable to deal with semi-structured, Unstructured data. Then along came distributed technologies such as Hadoop, which had the advantage of using inexpensive machines to store and process data. But HADOOP was designed to distribute data equally among the nodes in the cluster for storage and processing, ignoring the differences in the storage and computing capabilities of the cluster nodes themselves, and the performance of individual nodes even affects the performance of the collation system, and it is master-slave node processing data, there are data can tamper, system terminal is too single and so on. The contribution of this paper lies in the overall structure and technical route of the new rural cooperative medical system, and the optimization method of data flow of heterogeneous nodes, which can effectively save the scale and cost of the cluster, with the help of blockchain technology to ensure the security and credibility of data, optimize the front-end cluster service architecture, support multi-channel and high-concurrent key information push mode, has a very good promotion.</span>

Energy Efficient Beacon Scheduling in WSN

In wireless sensor network the main source of energy consumption is Idle listening. Keeping energy consumption in mind the wireless sensor network should quickly sensing data. The communication between the nodes is only possible when both nodes are in active state. In this paper, we have implemented a modified beacon scheduling in the recipient MAC protocol. the data will be transmitted to the node in the active state thus effectively saving the energy consumption in the idle state. For transmission of data, synchronization of all nodes is important. Each node has its defined time slot to avoid collision of data. The receiver node sends a beacon frame request to the slave node in active state in response to it the slave node sends data frame if any to the node. The communication takes place only in the active state thus saving the energy in passive state (sleep state). The system is simulated in visual basic software and the graphs are plotted accordingly. It also shows the active and sleepy state of the network.

Distributed system of virtual machines for self-organized networks

Introduction: Active data, being fragments of executable code transmitted between the nodes of an active network, are an effectivemechanism for the operation of software-reconfigurable distributed systems. Previously, in the works devoted to active data, not enoughattention was paid to the implementation of the runtime environment (the processor) for the executable code of active data, as well asto the issues of building hypervisors and load balancing in distributed systems. Purpose: Developing principles for the construction of virtual machines with active data, providing the reconfigurability of the target devices and network flexibility in general. Evaluatingthe possibility of using the existing approaches to load balancing for networks with active data. Methods: Our study uses the principlesof software-defined system development, the conception of active data, theoretical foundations and technology of virtualization.Results: Is has been proposed to use a distributed system of virtual machines as an active data execution environment, based on theobject-oriented approach to creating distributed applications. Each node of such a distributed system of virtual machines can act aseither a control or slave node during the object interaction. Based on the developed approach, we proposed to solve the problem ofbuilding a network of repeaters using active data, considering an unmanned aerial vehicle as an element of an active info-communicationnetwork which supports the active data technology. Since a distributed system of virtual machines enables asymmetric distribution ofdecentralized network nodes, a method has been developed for a distributed system whose nodes are unmanned aerial vehicles and acontrol node, to control the asymmetry value by creating objects of various decomposition levels. Practical relevance: The proposedmethods provide a way to control the resource consumption of the nodes of a distributed software-reconfigurable network and theamount of network data transmitted. For dynamic management of the load on the network nodes, a resource manager architecture anda resource allocation algorithm are developed.

Design of Multi Robots Based on Single Master Commands

In any type of communication in robots one too many communication is only possible. I.e. One master node can communicate with one slave node only. But here we are going to build up to two slave robots that communicate with the master node. This is possible only by using signee as it is alone having a separate unique id for it. Here we have used only two slave robots for one master node but, we can add a number of robots for the master node having of different id’s using of ZigBee transfer protocol.

Design and implementation of dimmer based smart street lighting system using raspberry Pi and IoT

In olden days street lights were not operated in an automatic way. Automation of street lights has become apparent these days. But we can notice that we do not require high intensity light during night hours, i.e. when there is no traffic, no people in the streets or on roads and even in the early mornings. As per requirement, the light intensity can be reduced using dimmer circuit. Light dependent resistor (LDR) sensors are used to sense the darkness and Passive Infrared (PIR) sensors are to detect the objects. Raspberry Pi (Master node) and Arduino (Slave node) will communicate each other and they help the proposed system to work more effectively. Current sensor and Voltage sensor are used to measure the current and voltage respectively. By reducing the intensity at these times, energy can be saved to some extent and the data is uploaded to the cloud. We can monitor and control the street lights in a smart way as per our requirement. Fault detection, minimization of cost, reducing the loss of electricity and man power are also possible. Hence, this proposed smart street lighting system will be helpful to the society in cost effective way.

A Distributed Algorithm for the Cluster-Based Outlier Detection Using Unsupervised Extreme Learning Machines

Outlier detection is an important data mining task, whose target is to find the abnormal or atypical objects from a given dataset. The techniques for detecting outliers have a lot of applications, such as credit card fraud detection and environment monitoring. Our previous work proposed the Cluster-Based (CB) outlier and gave a centralized method using unsupervised extreme learning machines to compute CB outliers. In this paper, we propose a new distributed algorithm for the CB outlier detection (DACB). On the master node, we collect a small number of points from the slave nodes to obtain a threshold. On each slave node, we design a new filtering method that can use the threshold to efficiently speed up the computation. Furthermore, we also propose a ranking method to optimize the order of cluster scanning. At last, the effectiveness and efficiency of the proposed approaches are verified through a plenty of simulation experiments.

The Influence of Equivalent Contact Area Computation in 3D Extended Node to Surface Contact Elements

This paper extends the frictionless penalty-based node to contact formulation with area regularization to a 3D framework. Based on our previous work [1] focused on axisymmetric modeling, two computational methods are also considered for the determination of the slave node area. The first method, named as the geometrical approach, is based on a force equivalence system, while the second one, named as the consistent approach, is derived from a more sophisticated scheme elaborated upon the virtual work principle. Then, the extended contact elements are derived for the contact formulations with geometrical and consistent area regularization and a consistent linearization is provided accordingly, which guarantees a quadratic rate of convergence of the global Newton Raphson iterative procedure. Finally, two numerical examples assess the performance of both contact formulations with area regularization and demonstrates the robustness and the efficiency of the node to surface contact formulation with consistent area regularization in reproducing a constant contact pressure distribution across the interface between a deformable body and a analytically-defined rigid body, irrespective of the mesh. Our findings will certainly encourage further developments towards the design of a penaltybased node to surface contact algorithm passing the contact patch test, as was already done successfully in 2D contact problems [2].

A Hardware Independent Real-time Ethernet for Motion Control Systems

Ethernet for Manufacture Automation Control (EtherMAC) is a new kind of real-time Ethernet used in motion control systems. It adopts a line topology with a standard industrial computer based master node and field-programmable-gate-array based slave nodes. EtherMAC employs one slave node to manage cycle communication and clock synchronization, so the real-time demand for its master node can be greatly reduced and dedicated hardware is no longer mandatory. Its distributed clock compensation mechanism can get synchronization accuracy in nanosecond order. The advantages of industrial computer and field programmable-gate-array are combined with EtherMAC, so that high control performance can be achieved.

A Study of Transmission Control Method for Distributed Parameters Measurement in Large Factories and Storehouses

For the characteristics of parameters dispersion in large factories, storehouses, and other applications, a distributed parameter measurement system is designed that is based on the ring network. The structure of the system and the circuit design of the master-slave node are described briefly. The basic protocol architecture about transmission communication is introduced, and then this paper comes up with two kinds of distributed transmission control methods. Finally, the reliability, extendibility, and control characteristic of these two methods are tested through a series of experiments. Moreover, the measurement results are compared and discussed.
