Modern pace of Information and Communication Technologies (ICT) progress requires rapid development of completely new approaches to data processing. One of the most important criteria that should be taken into account in every computing system nowadays is its energy efficiency. Strict requirements to service availability and timeliness must be taken into account as well. In this paper new comprehensive energy efficient approach to workload processing in distributed computing environment is proposed. The goal of this approach is to get as close as possible to the energy-proportional computing model. Proposed approach combines the advantages of horizontal scaling and energy efficient scheduling taking into account individual power consumption characteristics of computing nodes and dynamicity of workload in modern computing systems. The efficiency of the proposed approach is proven using Matlab modeling.

Content-Centric networking (CCN) is an alternative to host-centric networking exemplified by today's Internet. CCN emphasizes content distribution by making content directly addressable. Named-Data networking (NDN) is an example of CCN being considered as a candidate next-generation Internet architecture. One key NDN feature is router-side content caching that optimizes bandwidth consumption, reduces congestion and provides fast fetching for popular content. Unfortunately, the same feature is also detrimental to privacy of both consumers and producers of content. As we show in this paper, simple and difficult-to-detect timing attacks can exploit NDN routers as "oracles" and allow the adversary to learn whether a nearby consumer recently requested certain content. Similarly, probing attacks that target adjacent content producers can be used to discover whether certain content has been recently fetched. After analyzing the scope and feasibility of such attacks, we propose and evaluate some efficient countermeasures that offer quantifiable privacy guarantees while retaining key features of NDN.

Cloud computing provides access to computing resources for a fee. Client applications and services can be hosted in clouds. Cloud computing typically uses a network of data centers that are geographically dispersed. The distance between clients and applications is impacted by geographical distance. The geographical distribution of client requests can be random and difficult to predict. This suggests a need to reconsider the placement of services at run-time through migration. This paper describes a framework based on software-defined networking (SDN) principles. It demonstrates algorithms that are periodically executed and determine candidate services to migrate as well as target data centers to migrate to and an evaluation. The evaluation shows that effectiveness of the algorithms.

As data and knowledge volumes keep increasing, and global means for information dissemination continues to diversify, new methods, modeling paradigms and structures are needed to efficiently support the mounting scalability requirements for the large variety of current and future data, information, and knowledge [1–3]. Grid computing, peer-to-peer technology, data and knowledge bases, distributed information retrieval technology, and networking technology should all converge to address the scalability concern. This special section compiles recent work on addressing scalability issues of distributed and peer-to-peer systems. Selected papers from the Second international conference on Scalable Information Systems (INFOSCALE 2007) were invited for extension and submission to this special section. Finally, five papers were included in this special section.

With the emergence of Information-Centric networking as a potential paradigm shift in the computer networking field, the coupling between VANETS and Named-Data networking, known as VNDN, has gained momentum as a promising communication standard to foster the deployment of inter-vehicular communications in the real world, calling the attention of the research community. This work presents a concise VNDN review focusing on the background concepts. We also analyze the current status and open challenges, including the prominent data naming and caching approaches and the most efficient Interest and Data message forwarding and delivery strategies.

We introduce SpDISTAL, a compiler for sparse tensor algebra that targets distributed systems. SpDISTAL combines separate descriptions of tensor algebra expressions, sparse data structures, data distribution, and computation distribution. Thus, it enables distributed execution of sparse tensor algebra expressions with a wide variety of sparse data structures and data distributions. SpDISTAL is implemented as a C++ library that targets a distributed task-based runtime system and can generate code for nodes with both multi-core CPUs and multiple GPUs. SpDISTAL generates distributed code that achieves performance competitive with hand-written distributed functions for specific sparse tensor algebra expressions and that outperforms general interpretation-based systems by one to two orders of magnitude. © 2022 IEEE.

Fog computing is a promising computing paradigm that provides computing services close to end-users at edge of the network. Therefore, it supports large-scale, geographically distributed and latency-sensitive applications. However, due to its untrusty nature, numerous security challenges must be overcome. The integrity verification of the data in fog computing context is one of the main challenges to tackle. Indeed, most of existing solutions consider a centralized data storage context, and usually rely on a trusted third party to check data integrity. However, these approaches are not suitable for fog computing architecture, since the data is stored in a dynamic and a completely distributed manner. Motivated by these challenges, we propose in this paper, a new efficient public verification scheme that protects the integrity of the data in fog computing architecture. Our scheme secures data integrity and authenticity based on the short integer solution SIS problem and the identity-based signatures. In addition, it allows to efficiently verify the integrity of data, even when it is separately shared on multiple servers. This verification can be performed by any end-user on the architecture, and without relying on any trusted third party. Finally, we show through extensive simulation that our solution is highly effective and outperforms existing solutions.

Internet of things is a new technology which is heavily affecting different aspects of human life. The number of smart devices connecting to IoT and the amount of data gathered or produced by these devices are increasing. In order to organize, secure and analyse the IoT data, novel and creative ideas for IoT design and management are required. Software Defined networking is a new and promising paradigm. Its main idea is to decouple the control functions from physical devices and set them inside a logically centralized control layer. In this paper, a distributed approach is proposed for accelerating data management and balancing the load between IoT devices based on SDN principles. The proposed framework makes it possible to apply different management strategies in a distributed manner. Experimental results indicate that our scheme distributes tasks between devices equally and exhibits a reduction in the average turnaround time and the average waiting time and it will improve the processing performance.

The development situation of communication system of small satellites in formation in China and aboard is first introduced. With the development of small satellites at present and the needs of small satellites for space flying mission, the fundamental technologies of hardware structure supporting reconfigurable computing based on FPGA and the distributed computing technology are analyzed in this paper. The application of these two technologies in formation-flying pico-satellites communication is demonstrated, and it is verified through an experiment of distributed compressing images that the distribution technology can be implemented in such a reconfigurable hardware structure. The combination of these two technologies can make good use of software and hardware sources of pico-satellite. A design scheme of pico-satellite based on these two technologies is presented at last.
