Cloud computing and digital forensics are both developing topics and researching these topics requires an understanding of the main aspects of both cloud computing and digital forensics. In cloud computing it is necessary not only to understand its characteristics and the different services and deployment models but also to survey the underpinning elements of cloud computing such as virtualization and the distributedcomputing which are important to identify its impact on current digital forensics guidelines and procedures. Unlike papers discussing the challenges and opportunities presented by cloud computing in relation to digital forensics, in this paper, we will discuss the underpinning cloud computing elements which are required to provide forensics friendly cloud services. Furthermore, we suggest a set of questions that will aid in the process of cloud forensics analysis.

the high efficiency and reliability of the Tactile internet (TI) primarily depends on the construction of the architecture of the distributed service platform. therefore, the main goal of the work is to analyze and present an effective solution for building a Tactile internet domain architecture model with high reliability, availability, and low latency. In this article, the domain architecture consists of three sections, namely: master, slave, and network domains. Using haptic commands and haptic feedback signals, the master and slave domains communicate across the network domain. To implement the construction of the network domain architecture, the article proposes the use of a new technology, such as mobile edge computing (MEC) with an open fog structure (OpenFog).

the increase in the number of internet of things (IoT) devices and their vast streaming data, results in data explosion. Context awareness has also become essential in software applications for better service delivery to users. It poses the urgent need for scalable integrated software systems which can analyze, store, extract meaningful events and to deliver information to the customers in real-time considering their context. A highly scalable architecture is proposed which uses distributed queues for decomposability and comprises of three functional components. 1. distributed complex event integrated system where each of the complex event processing engines are taking care of event detection, 2. the context detection module which extracts contextual information and match them with detected events and, 3. A notification module and an application programming Interface is provided for the bulk alert information delivery. the presented model evaluation shows that our system well suits the current trend and requirements of IoT applications.

Linking the physical world to the internet, also known as the internet of things, has increased available information and services in everyday life and in the Enterprise world. In Enterprise IT an increasing number of communication is done between IT backend systems and small IoT devices, for example sensor networks or RFID readers. this introduces some challenges in terms of complexity and integration. We are working on the integration of IoT devices into Enterprise IT by leveraging SOA techniques and Semantic Web technologies. We present a SOA based integration platform for connecting WSNs and large enterprise business processes. For ensuring interoperability our platform is based on Linked Services. these are thoroughly described, machine-readable, machine-reasonable service descriptions.

there are numerous distributed new energy and diversified loads in the regional energy internet. New business demands such as virtual power plant group dispatching and control, demand side response, and energy big data centers are constantly emerging, putting higher requirements on the reliability, security, and processing capacity of communication networks. As the core of the regional energy internet, the power grid’s advanced communication and computing resources management is an effective way to meet the needs of the new business. In order to meet the differentiated requirements of services and security isolation, the network slicing technology is applied to the power grid. In this paper, we proposed a computing and bandwidth resource management scheme in smart grids enabled by regional energy internet to reduce energy consumption and network delay. We modeled the joint allocation of bandwidth and computing resources of network slicing as a convex optimization problem, aiming to minimize the weighted sum of system delay consumption and computational energy consumption. the Lagrange multiplier iterative optimization method is used to solve the optimal allocation scheme of computing resources and bandwidth resources. the simulation results show that the proposed solution can meet the differentiated delay requirements of the service and effectively reduce the delay consumption and energy consumption of the system.

Withthe growing number and ubiquitous usage of Web services throughout the service-oriented community, the need to find service descriptions in a given repository, as well as composing them to a desired output, becomes a major issue in both research and corporate environments. Considering emerging semantic technologies and methods for service matching that is not limited to a mere syntactic level, the need for fast discovery and composition algorithms arises. In this paper we present a system created at the VitaLab in Vienna withthe purpose to overcome the obstacles which are implications of both, large service repositories and large ontologies to describe semantic relations.

Because the broad application prospects of internet of things (IoT) and the progress of short-range wireless technology, the internet and the intelligent terminals have an explosive growth, IoT is expected to become the next trillion-dollar information industry. In wired/wireless technologies, the machine to machine (M2M) communications have higher request to benefit people, include e-health, family energy management and entertainment. this paper represents technical indexes, application range, radio coexistence mechanism and suitable network standards of key radio technologies. In the application layer, this paper argues the cloud computingtechnology as the center to help process a large amount of data of the sensing layer, for providing efficient services to clients and effectively reducing the cost of smart home withthe help of data processing.

the modern distributed systems introduce new constraints. therefore, there are subject to different types of faults. A running application should proceed normally and especially end to achieve its goals despite the presence of faults. Hence, the fault tolerance is very important in this context. Among the fault tolerance techniques, we consider in this study, the checkpointing based recovery by proposing a new hybrid checkpointing protocol for MANETs.
