In this paper, we propose a novel architecture that utilizes features of Blockchain, fog computing, and cloud computing to manage IoT data. Blockchain allows to have a distributed peer-to-peer network in which non-trusting participants can interact with each other without a trusted intermediary or third party. We evaluate how this mechanism works to face the challenges of IoT with respect to multiple accessibility to IoT devises. We consider a Blockchain architecture in presence of edge computing layer. With fog or fog computing, the sensitive data can be analyzed locally instead of sending it to the cloud for analysis. Edge nodes can also keep track and control of the IoT devices that collect, analyze and store data. We show that this control can be better executed when Software Defined Network (SDN) and Network Functions Virtualization (NFV) are integrated into our process for optimal resource management. In this paper, we present our system architecture with a detailed description of the different interactions. We remark that the integration of Blockchain, IoT, and edge computing when coupled with SDN and NFV-enabled cloud infrastructure can bring to more superior and efficient platform for accessing, managing, and processing the huge influx of IoT data.

In recent years, precision agriculture and Wireless Sensor Network (WSN) technology have attracted great attention and concentration in industrial and academic levels. The combination between WSNs and the agricultural sector will be beneficial to solve several issues and challenges. This combination can realize a set of benefits such as improving the quality of the agricultural product, increasing the efficiency of production, improving the efficiency of crop, and conserving energy and water resources. Precision agriculture manages a set of different services (e.g., irrigation, fertilization), especially irrigation systems. The irrigation system is considered one of the most critical factors for successful agricultural production and development of the agriculture. However, the current irrigation systems are characterized by poor performance and a significant increase in demand for agricultural productivity. In addition, these current systems are affected by many factors and problems such as the water scarcity, drought, and waste of limited water resources. To correct these problems, we propose a prototype for an intelligent irrigation system that is based on the integration of a drip irrigation technique with the wireless sensor network. In this paper, we develop an automated and intelligent irrigation technique using a WSN and ZigBee wireless communication technology for saving water and increasing the performance and efficiency of irrigation systems and we present the operation and design of this system. The proposed system controls irrigation water through the detection of temperature and soil moisture and other environmental parameters;the data is measured using several special sensors deployed near the root part of plants. This system also allows an analysis and checks the measured data with a developed base of threshold values for each measured parameter in order to activate or deactivate the irrigation mechanism. The main aims of our proposed system are savi

Due to the evolution of technologies and need to observe and manage hostile environments, Wireless Sensor networks (WSNs) are becoming essential and implicated in most fields of life. The agricultural sector is one of such sectors where WSNs are successfully utilized to achieve many benefits. For successful agriculture, the irrigation is one of the most important factors, where it plays a tactical role in the process of agriculture but is considered one of the world's largest freshwater consumers. Besides, the water scarcity, drought, and irrational wastage of water resources are among the critical issues that touch almost all sectors, notably agricultural services, and especially irrigation. These facts lead all governments around the world to rethink about saving water and reducing the amount of water used in irrigation;this requires the development of irrigation practices in order to obtain a complete and independent system for the management of irrigation more efficient. Consequently, selection of using WSNs in irrigation system will be a benefit for developing the agriculture, and thus saving water and improving and increasing production. In this work, we propose a new model of a complete and smart irrigation system based on wireless sensor networks, and we introduce and discuss our proposed system. The suggested system controls and regulates irrigation system by monitoring a set of environmental parameters, i.e., soil and weather properties, using soil and weather sensor nodes and improving techniques of decision-making to estimate requirements of each crop (e.g., amount of water required), and therefore can make the decision to activate or disable irrigation.

Cloud Computing is an evolving term that is subject to security threats, vulnerabilities, and attacks. Latterly, various classifications and taxonomies have been suggested to characterize and classify cloud security issues. Some of them are based on general security factors, such as the CIA triad (confidentiality, integrity, and availability), while others specify cloud security classes. Most of these classes are determined by the cloud's attributes, such as Cloud service models, cloud deployment models, and cloud actors. In this paper, we explore the already existing criteria and dimensions considered in the development of cloud computing security classification/taxonomy. Then, we study and compare their strengths and characteristics. Thereafter, our objective is to provide and develop exhaustive cloud security taxonomy and push researchers to better comprehend the nature of any newly introduced threat or attack, categorize them, and explain the relationship between threats and other categories or subcategories.

In Cloud Computing Environment, using only static security measures didn't mitigate the attack considerably. Hence, deployment of sophisticated methods by the attackers to understand the network topology of complex network makes the task easier. For this reason, the use of dynamic security measure as virtual machine (VM) migration increases uncertainty to locate a virtual machine in a dynamic attack surface. Although this, not all VM's migration enhances security. Indeed, the destination server to host the VM should be selected precisely in order to avoid externality and attack at the same time. In this paper, we model migration in cloud environment by using continuous Markov Chain. Then, we analyze the probability of a VM to be compromised based on the destination server parameters. Finally, we provide some numerical results to show the effectiveness of our approach in term of avoiding intrusion.

Due to the proliferation of cloud computing and Internet of Things (IoT) systems in healthcare industry, remote real-time monitoring and tracking of patient conditions have become the norm. In a typical deployment, Medical IoT (MIoT) devices transmit patient data to a medical datacenters where the data get stored, analyzed, and made available to concerned parties or individuals. Healthcare providers, physicians and care takers can access remotely these medical data located in these medical datacenters which are typically deployed as a private cloud or public cloud. In such cloud deployment, the performance services to access the data in a timely manner is critical. One of the key performances metrics is the response time. It is important to deploy the medical datacenters in a cloud environment in a way to minimize the response time. Moreover, Fog/Edge computing layer is also used to perform localized processing and storage to further reduce response time. This paper studies, models, and shows how to reduce computing resources cost while guaranteeing health requests performance constraints-particularly response time of accessing medical data stored in a fog-cloud environment. To address this issue, this paper proposes a queuing model to predict the minimum required number of computing resources (both fog and cloud nodes) to meet the Service Level Agreement (SLA) for response time. We verify and cross validate our analytical model through discrete event simulation. Obtained results from our analytical models show that the proposed model is able to correctly and effectively predict the number of computing resources needed for health data services in order to achieve the required response time under different workload conditions. © 2018 IEEE.

Cloud computing has emerged as a new commercial infrastructure paradigm which has revolutionized the IT industry. It has particularly the advantage of delivering a exible, high-performance, pay-as-you-go, on-demand service. Maintaining the Quality of Service (QoS) at an acceptable level for cloud customers requires an accurate and well adapted performance analysis mechanism. The QoS required by customers is guaranteed using a Service Level Agreement (SLA) document. This has increased the complexity for service providers as they now have to not only managed their resources but also they need to provide expected QoS for customers. In this paper, we study a model which associates a scheme for Virtual Machine (VM) instantiation in a given physical machine (PM) with a mechanism to control the access for incoming requests to the Virtual Machine Monitor (VMM). In this model the number of activated VMs in the PM is defined according to the number of jobs in the system, and the control access is based on the load of the system. We develop an analytical model, derive performance parameters expressions and give numerical examples to show how the model estimates these QoS parameters. In particular, we plot the loss probability, mean number of requests in the system and mean requests delay while varying the incoming request arrival rate for two systems (system under control and system with no control). We cross-validate our analytical model using MATLAB software implementation. Analysis results obtained show the positive impact of the proposed mechanism on the QoS parameters. © 2017 ACM.
