SDMEC: Software Defined System for Mobile Edge Computing

Abstract: 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.

SDSecurity: A Software Defined Security experimental framework

Abstract: The emerging Software Defined Systems (SDSys) is a recent paradigm, which has been introduced to reduce the overhead in the control and management operations of complex computing systems. The main concept behind this technology is around isolating the data plane from the control plane. Traditional security mechanisms are facing more challenges in providing sufficient levels of protection and efficiency. SDSys for security has been proposed to address these challenges. Software Defined Security (SDSec) provides a flexible and centralized security solution by abstracting the security mechanisms from the hardware layer to a software layer. In this paper we present a novel experimental framework to provide a novel virtualized testbed environment for SDSec systems. 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 for SDSec. To the best of the authors' knowledge, this is the first experimental framework and simulator for SDSec solutions. The developed simulator, will not only support the development and testing of SDSecurity solutions, it will also serve as an experimentation tool for researchers and for benchmarking purposes. The developed simulator could also be used as an educational tool to train students and novice researchers.

Magnetic field effect on heat transfer and fluid flow characteristics of blood flow in multi-stenosis arteries

Abstract: Heat and fluid flow characteristics of blood flow in multi-stenosis arteries in the presence of magnetic field is considered. A mathematical model of the multi-stenosis inside the arteries is introduced. A finite difference scheme is used to solve the governing equations in terms of vorticity-stream function along with their boundary conditions. The effect of magnetic field and the degree of stenosis on wall shear stress and Nusselt number is investigated. It was found that magnetic field modifies the flow patterns and increases the heat transfer rate. The severity of the stenosis affects the wall shear stress characteristics significantly. The magnetic field torque will increase the thermal boundary layer thickness and the temperature gradient in the streaming blood, and hence increasing the local Nusselt number
