This paper presents the network level security services currently available for the Internet infrastructure. Since IPsec is likely to become the largely accepted standard as far as IP level security is concerned, the paper describes the IPsec architecture including its defined security formats and the related key management procedures. Finally, common IPsec applications are presented and the fu...

With internet expanding in every aspect of businesses infrastructure, it becomes more and more important to make these businesses infrastructures safe and secure to the numerous attacks perpetrated on them conspicuously when it comes to denial of service (DoS) attack. IP is an internet protocol each and every system having a unique address to use this address to communicate to the internet. The...

This paper presents a computing hosting system to provide virtual computing laboratories for learning activities. This system is based on hosting and virtualization technologies. All the components used in its development are free software tools. The computing lab model provided by the system is a more sustainable and scalable alternative than the traditional academic computing lab, and it requ...

In vehicular networks, vehicles exchange messages with each other as well as infrastructure to prevent accidents or enhance driver’s and passenger’s experience. In this paper, we propose a grid-based multichannel access scheme to enhance the performance of a vehicular network. To determine the feasibility of our scheme, we obtained preliminary results using the OPNET simulation tool. Keywords— ...

The wireless communication is one of the widely used methods of data transfer at the present days. The benefit of this communication method is the partial independence of the infrastructure and the possibility of mobility. In some special applications it is the only way how to connect. This paper presents some problems in the implementation of a sensor network connection for measuring environme...

We discuss a systematic approach to network forensic collection and analysis of data in converged networks. Since attacks cannot be completely avoided, it is necessary to have appropriate forensics systems. Upon integration into a network forensic infrastructure, we expect this forensic model will enable a faster response and more structured investigations of Voice over IP (VoIP)-based network ...

The wide spread of cloud computing has identified the need to develop specialized approaches to the design, management and programming for cloud infrastructures. In the article were reviewed the peculiarities of the hybrid cloud and middleware software development, adaptive to implementing the principles of governance and change in the structure of storing data in clouds. The examples and resul...

In recent years telecommunications services in remote Australia have received considerable attention, with services for indigenous desert communities a key focus. This project, known as Desert Interactive Remote Television (DIRT), uses existing community rebroadcast TV infrastructure to provide low cost multimedia messaging services for remote desert communities. The system architecture, key ap...
