In this paper, the authors propose a SDN based disaster-aware smart routing scheme for highly-available information storage systems. The authors' proposed scheme is based on the concept of Symbiotic Computing to recognize disaster status in Real Space, and provides appropriate routes form Digital Space dynamically. This realizes effective data transmission considering disaster situation and its time variation. In this paper, the authors design and implement their proposed scheme with dynamic multipath routing and parallel data transmission to enhance the network performance. They also evaluate its effectiveness through large-scale network environments.

Key Innovations

AbstractTechnological leaps are often driven by key innovations that transform the underlying architectures of systems. Current DNA storage systems largely rely on polymerase chain reaction, which broadly informs how information is encoded, databases are organized, and files are accessed. Here we show that a hybrid ‘toehold’ DNA structure can unlock a fundamentally different, dynamic DNA-based information storage system architecture with broad advantages. This innovation increases theoretical storage densities and capacities by eliminating non-specific DNA-DNA interactions common in PCR and increasing the encodable sequence space. It also provides a physical handle with which to implement a range of in-storage file operations. Finally, it reads files non-destructively by harnessing the natural role of transcription in accessing information from DNA. This simple but powerful toehold structure lays the foundation for an information storage architecture with versatile capabilities.

Competing Interactions

Arrays of ordered segmented nanowires are considered as a promising material for three-dimensional information storage systems. However, the presence of a large number of competing interactions significantly complicates the description of the magnetic behavior of such systems. In this work, the influence of the length of the nickel segment on the integral magnetic properties of the array is investigated. In particular, it is shown that the change in the direction of the easy axis of magnetization occurs when the segment length to diameter ratio is in the range from 10 to 20.

Efficient Storage

Introduction: Currently, we witness an explosive growth in the amount of information produced by humanity. This raises new fundamental problems of its efficient storage and processing. Commonly used magnetic, optical, and semiconductor information storage devices have several drawbacks related to small information density and limited durability. One of the promising novel approaches to solving these problems is DNA-based data storage. Purpose: An overview of modern DNA-based storage systems and related information-theoretic problems. Results: The current state of the art of DNA-based storage systems is reviewed. Types of errors occurring in them as well as corresponding error-correcting codes are analized. The disadvantages of these codes are shown, and possible pathways for improvement are mentioned. Proposed information-theoretic models of DNA-based storage systems are analyzed, and their limitation highlighted. In conclusion, main obstacles to practical implementation of DNA-based storage systems are formulated, which can be potentially overcome using information-theoretic methods considered in this overview.
