SDIoT: a software defined based internet of things framework

The internet of things (IoT) represent the current and future state of the Internet. The large number of things (objects), which are connected to the Internet, produce a huge amount of data that needs a lot of effort and processing operations to transfer it to useful information. Moreover, the organization and control of this large volume of data requires novel ideas in the design and management of the IoT network to accelerate and enhance its performance. The software defined systems is a new paradigm that appeared recently to hide all complexity in traditional system architecture by abstracting all the controls and management operations from the underling devices (things in the IoT) and setting them inside a middleware layer, a software layer. In this work, a comprehensive software defined based framework model is proposed to simplify the IoT management process and provide a vital solution for the challenges in the traditional IoT architecture to forward, store, and secure the produced data from the IoT objects by integrating the software defined network, software defined storage, and software defined security into one software defined based control model.

SDStorage: A Software Defined Storage Experimental Framework

With the rapid growth of data centers and the unprecedented increase in storage demands, the traditional storage control techniques are considered unsuitable to deal with this large volume of data in an efficient manner. The Software Defined Storage (SDStore) comes as a solution for this issue by abstracting the storage control operations from the storage devices and set it inside a centralized controller in the software layer. Building a real SDStore system without any simulation and emulation is considered an expensive solution and may have a lot of risks. Thus, there is a need to simulate such systems before the real-life implementation and deployment. In this paper we present SDStorage, an experimental framework to provide a novel virtualized test bed environment for SDStore systems. The main idea of SDStorage is based on the Mininet Software Defined Network (SDN) Open Flow simulator and is built over of it. The main components of Mininet, which are the host, the switch and the controller, are customized to serve the needs of SDStore simulation environments.

SDDC: A Software Defined Datacenter Experimental Framework

The rapid growth and the distributed sites of the datacenters increase the complexity of control and management processes. A new paradigm which is called Software Defined Systems (SDSys) comes as a solution to reduce the overhead of datacenters management by abstracting all the control functionalities from the hardware devices and setting it inside a software layer. These functionalities are responsible for organizing and controlling the main blocks of the datacenter; network, storage, compute and security. The Software Defined Datacenter (SDD) integrates the software defined concepts into all of these main blocks. Transferring these concepts into workable systems requires checking several performance aspects and testing its correctness before building real systems. In this paper we introduce a novel experimental framework (SDDC) to provide a novel virtualized testbed environment for SDD systems. This work builds on the Mininet simulator, where its core components, the host, the switch and the controller, are customized to build the proposed experimental simulation framework for SDD. This simulator lets the users develop and test their own SDD solutions, and at the same time gives the researchers an experimentation tool for benchmarking purposes. The developed simulator could also be used as an educational tool to train students and novice researchers.

SDMEC: Software Defined System for Mobile Edge Computing

Mobile Edge Computing (MEC) promises a paradigm shift in enabling efficient Mobile Cloud Computing (MCC) services by providing storage and processing capacity within the access range of the mobile devices. In MEC, Mobile Edge (ME) servers are placed at the edge of the mobile networks eliminating the need to offload compute-/storage-intensive tasks of the mobile devices to the core of the network (the centralized cloud data center). This reduces the network latency and enhances the quality of service provided for the mobile end users. Different applications can benefit from the large scale deployments of ME servers such as smart grid applications, content delivery networks, content sharing, traffic management, and E-health applications. This promising paradigm comes with its own downside related to the management complexity of large scale deployments that offers hundreds of applications to millions of users. In this paper, we introduce a software defined based framework to enable efficient MCC services through the integration of different software defined system components with the MEC system.

A novel framework for software defined based secure storage systems

Abstract The Software Defined Systems (SDSys) paradigm has been introduced recently as a solution to reduce the overhead in the control and management operations of complex computing systems and to maintain a high level of security and protection. The main concept behind this technology is around isolating the data plane from the control plane. Building a Software Defined System in a real life environment is considered an expensive solution and may have a lot of risks. Thus, there is a need to simulate such systems before the real-life implementation and deployment. In this paper we present a novel experimental framework as a virtualized testbed environment for software defined based secure storage systems. Its also covers some related issues for large scale data storage and sharing such as deduplication. This work builds on the Mininet simulator, where its core components, the host, switch and the controller, are customized to build the proposed experimental simulation framework. The developed emulator, will not only support the development and testing of SD-based secure storage solutions, it will also serve as an experimentation tool for researchers and for benchmarking purposes. The developed simulator/emulator could also be used as an educational tool to train students and novice researchers.

The Arabian E-government websites accessibility: A case study

Nowadays, most people are using the Internet to achieve their daily needs. One of these needs is the ability to access the government websites, to make the necessary transactions and procedures via the internet. Maintaining the transaction over the web arises the needs of building an available and accessible website for all users, even those with special needs. In this paper, we evaluate the accessibility for a set of Arabian E-government websites with two versions, English and Arabic, by using a set of automated tools. The results obtained from the two versions are compared to decide which is the best government website that achieved the least number of errors. The selected accessibility tools are supporting the Web Contents Accessibility Guidelines (WCAG) version 2.0 as an update of the previous version WCAG 1.0.

Software Defined based smart grid architecture

The diversity, continuous expansion and the large number of smart grid resources increase the complexity of such systems and arise the need to find a new way to manage these resources and, at the same time, reduce the complexity in the control and monitoring operations. Moreover, smart grid Systems are considered critical systems requiring reliable and real time data delivery and an efficient, flexible, scalable control solution to satisfy the system requirements. Thus, in this paper, we introduce a new architecture model for smart grid networks based on the Software Defined Systems (SDSys) paradigm. The main idea behind the SDSys revolves around abstracting the control plane out of the data plane and setting it at a separate layer in the middleware. Different forms of SDSys like Software Defined Network (SDN), Software Defined Storage (SDStore), Software Defined Security (SDSec) and Software Defined Internet of Things (SDIoT) are used to provide a comprehensive smart grid control solution which hide the complexity that exists in traditional control techniques. Meanwhile, we show how the proposed model can provide an accurate, reliable, secure, extensible and network-aware architecture design for smart grid network. Furthermore, we explain how it can provide a single point of view for all smart grid resources and a programmable interface to adapt the network for any sudden changes.
