Cloud acts as a data storage and also used for data transfer from one cloud to other. Here data exchange takes place among cloud centers of organizations. At each cloud center huge amount of data was stored, which interns hard to store and retrieve information from it. While migrating the data there are some issues like low data transfer rate, end to end latency issues and data storage issues will occur. As data was distributed among so many cloud centers from single source, will reduces the speed of migration. In distributed cloud computing it is very difficult to transfer the data fast and securely. This paper explores MapReduce within the distributed cloud architecture where MapReduce assists at each cloud. It strengthens the data migration process with the help of HDFS. Compared to existing cloud migration approach the proposed approach gives accurate results interns of speed, time and efficiency.

In this article is being reviewed different approaches to optimize data exchange in a network using cryptography - to make any date secure, compression - to make any data smaller and accelerated routing, which is based on meta information about target destination: how far they are, how loaded they are. The object of research is the process of data exchange in the network. The purpose of the study is to optimize the process of data exchange in the network in order to improve the security and speed of data transfer. Research methods - statistical analysis of data transmission efficiency indicators. When transmitting data, cryptographic algorithms are used to ensure integrity and security, these algorithms allow the exchange of data using public and private key technology. But now this may not be enough to complicate the process of decrypting the data, it is advisable to make the messages transmitted between nodes as similar as possible to each other, for example, the same length. This solution will minimize the possibility of revealing the cipher by analysis for the attacker, but at the same time significantly increases the volume of transmitted messages due to the additional «masking» amount of data. To compensate for this effect in high-load networks, it is proposed to use a smart routing algorithm, which allows you to choose the optimal route for messages, taking into account the load of routers and channels between them.

The paper considers issues of data migration from corporate information systems of clients for localizing defects on the developer’s side. The main revealed problem is the defects localization on the client side. As a solution, an approach to data banks processing is proposed. The approach is based on the defect data exchange method and the defect presentation model. The paper describes an information flows model of a corporate system in the context of the detected defects layer (data cast). The main task of data banks processing in defect localization is determined. It is the selection of data cast for a specified time period. A defect model is proposed in the form of a parameters set for data selection, which is built on the metadata concept. The model is defined as a tuple of data records from a set of interrelated entity tables for some time period. Thus, application of the proposed approach will automate the data migration process between client and developer systems and, in general, will increase the efficiency of corporate information systems support by reducing the processed and sent information. The results of a computer experiment showed that the data volume during the migration process significantly decreased. To approach will improve the efficiency of maintaining corporate systems by reducing the processed and transmitted information. Potentially, this model can be applied in the inverse problem – to migrate data from the developer’s side to the client. It is supposed to carry out processing on a database of any size and structure.

As the data transmission speed and the efficiency over the wireless network depend on the network or transfer device bandwidth. After physical implementation of wireless network which is difficult to dynamically control transfer in order to get high or low data transfer rate. Dedicating the fixed network for such a dynamic requirement network is not feasible. Many researchers are trying to enhance the wireless network speed by joining the transfer speed of multiple lines which will result in to asynchronous data transfer and data leakage. Hence the proposed system is to design and implements a dynamically controllable wireless network using the multiple radio frequency wireless devices. Here the proposed system will use multiple wireless devices and transfer data over multiple line depending upon the user configuration and synchronize the data over the receiving end. It will let the user control the wireless data transmission speed as per the requirement.

The higher activity of data exchange transactions both online and offline raises concerns for some parties, large data sizes result in a waste of memory and slow data transfer and delivery processes. For this reason, a technique is needed to change the size of the data to be smaller. This technique is called compression or better known as data compression. Data compression is a process of converting a set of data into a form of code to save data storage requirements. Fixed Length Binary Encoding Algorithm (FLBE) uses a lossless technique that does not eliminate information at all, only representing some of the same information. The results obtained from the application of Fixed Length Binary Encoding algorithm in the process of compression and decompression include compression capacity, compression ratio and compression and decompression time. In accordance with the results of the experiments carried out, it can be seen that the data originally having a larger size can be compressed well implemented in text files.

Computers nowadays have different components for data storage and data processing, making data transfer between these units a bottleneck for computing speed. Therefore, so-called cognitive (or neuromorphic) computing approaches try combining both these tasks, as is done in the human brain, to make computing faster and less energy-consuming. One possible method to prepare new hardware solutions for neuromorphic computing is given by nanofiber networks as they can be prepared by diverse methods, from lithography to electrospinning. Here, we show results of micromagnetic simulations of three coupled semicircle fibers in which domain walls are excited by rotating magnetic fields (inputs), leading to different output signals that can be used for stochastic data processing, mimicking biological synaptic activity and thus being suitable as artificial synapses in artificial neural networks.

Abstract Background A “pill-in-the-pocket” anticoagulation strategy, guided by ECG data from an implantable loop recorder (ILR), has been advocated as a clinical strategy. However, a fundamental requirement is the ability to reliably obtain daily ECG data from patients. Objective To determine the reliability of daily ECG data transfer from ILRs. Methods We evaluated patients implanted with an ILR in whom we sought to withhold oral anticoagulation (OAC) unless atrial fibrillation (AF) was detected. The ILR transmits data nightly to a bedside monitor. Once received, the data are sent to a central server. Over the course of a month, we tracked for each patient whether ECG data were received by the server. Results The study included 170 AF patients with an ILR where we planned to withhold OAC unless AF was documented. Daily ECG data were automatically transmitted and retrievable in only 36 (21%) patients. Two (1%) pts had not a single day of connectivity, 6 (4%) pts were connected <7 days, and 16 (9%) pts were connected <14 days. Wireless connectivity was lost for >48 hours in 89 (52%) patients (Figure). Most patients experienced multiple reasons for data transmission failure within the month. Conclusions To determine whether an ILR guided OAC strategy is feasible, reliable daily transmission of ECG data is a fundamental prerequisite. Current technology facilitated daily ECG data transfer in only 1/5 of patients. In the remaining, there was either extended loss of connectivity or no connectivity at all. A “pill-in-the-pocket” anticoagulation approach is currently difficult given existing hardware limitations. Funding Acknowledgement Type of funding source: None
