Currently, the Virtual Private Network (VPN) support offered by FreeBSD is quite limited: it provides a way to establish tunnels but it does not consider the problems of multiple VPNs concurrently deployed on the same machine. Our implementation enables the provisioning of VPN services on FreeBSD by extending its routing and forwarding infrastructure. We adopted the virtual router approach, by ...

Cloud computing is a solution to problems of Modern day Software companies that needs fast, secure and scalable IT infrastructure, which helps organizations to focus on their core business rather than worrying about the investment and maintenance of their IT infrastructure. Software Testing is a challenging activity for every software engineering projects and it is one of the five main technica...

Many cities in the Global South are structurally different from Northern, particularly American, on which much of urban sociology’s conceptual apparatus has been based. Thus, depicting them terms a standard vocabulary risks imposing an inappropriate way seeing. We need that is able to accommodate their experience. This special issue contributes work building vocabulary. select five keywords soc...

The FAA Alternative Position Navigation and Timing effort is developing technologies to provide navigation service capable of sustaining operations in the event of the loss of Global Navigation Satellite Systems (GNSS). APNT will utilize existing ground infrastructure to support this capability. One effort is to examine the use of the Automatic Dependent Surveillance Broadcast (ADS-B) ground in...

In this article, we present a web server based solution for implementing a system for intelligent navigation. In this solution we use real time collected data and traffic history to establish the best route for navigation. This is a low cost solution that is easily to implement and extend. There is no need any infrastructure at road network level except only a device that collect data about tra...

This paper considers an approach for partial reduction of the overhead implied by request for data security within the Smart Grid communications infrastructure. A significant part of the implementation and processing overhead appears as a consequence of the data confidentiality request and the related requirement for massive data encryption. Accordingly, this paper points out to the related req...

The progressive distribution of the components in Mobile Edge Computing at different locations, need to be controlled from a centralized logical unit. This paper proposes a new controlling unit between the mobile transport network and the cloud infrastructure, called Mobile Edge Computing Manager, which reuse the concept of the Black Rider, which is contextand policy-based itself. This centrali...

Personal Networks (PN) are future communication systems that combine wireless and infrastructure based networks to provide users a variety of services anywhere and anytime. PNs introduce new design challenges due to the heterogeneity of the involved technologies, the need for self-organization, the dynamics of the system composition, the application-driven nature, the co-operation with infrastr...

Cloud computing is an emerging paradigm with three main facets: Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS). Several benefits are expected from cloud-based conferencing (e.g. efficiency in resource usage, easy introduction of new conferencing applications). This paper proposes a publication and discovery architecture for the interactions bet...
