Hybrid Simulation and Test of Vessel Traffic Systems on the Cloud

This paper presents a cloud-based hybrid simulation platform to test large-scale distributed System-of-Systems (SoS) for the management and control of maritime traffic, the so-called Vessel Traffic Systems (VTS). A VTS consists of multiple, heterogeneous, distributed and interoperating systems, including radar, automatic identification systems, direction finders, electro-optical sensors, gateways to external VTSs, information systems; identifying, representing and analyzing interactions is a challenge to the evaluation of the real risks for safety and security of the marine environment. The need for reproducing in fabric the system behaviors that could occur in situ demands for the ability of integrating emulated and simulated environments to cope with the different testability requirements of involved systems and to keep testing cost sustainable. The platform exploits hybrid simulation and virtualization technologies, and it is deployable on a private cloud, reducing the cost of setting up realistic and effective testing scenarios

Application of Asynchronous Transfer Mode (Atm) technology to Picture Archiving and Communication Systems (Pacs): A survey

Broadband Integrated Services Digital Network (R-ISDN) provides a range of narrowband and broad-band services for voice, video, and multimedia. Asynchronous Transfer Mode (ATM) has been selected by the standards bodies as the transfer mode for implementing B-ISDN; The ability to digitize images has lead to the prospect of reducing the physical space requirements, material costs, and manual labor of traditional film handling tasks in hospitals. The system which handles the acquisition, storage, and transmission of medical images is called a Picture Archiving and Communication System (PACS). The transmission system will directly impact the speed of image transfer. Today the most common transmission means used by acquisition and display station products is Ethernet. However, when considering network media, it is important to consider what the long term needs will be. Although ATM is a new standard, it is showing signs of becoming the next logical step to meet the needs of high speed networks; This thesis is a survey on ATM, and PACS. All the concepts involved in developing a PACS are presented in an orderly manner. It presents the recent developments in ATM, its applicability to PACS and the issues to be resolved for realising an ATM-based complete PACS. This work will be useful in providing the latest information, for any future research on ATM-based networks, and PACS

DSL-based triple-play services

This research examines the triple play service based on the ADSL technology. The voice over IP will be checked and combined with the internet data by two monitoring programs in order to examine the performance that this service offers and then will be compared with the usual method of internet connection.This research examines the triple play service based on the ADSL technology.

Effect of real video streaming over virtual MANET environment

Wireless Ad hoc Network is promising in solving many challenging real-world communication problems. Examples of these are: military field operation, emergency response system, and oil drilling and mining operation. However, the wide deployment of this type of network is still a challenging task. It is very difficult to manage quality of services for real time applications like video transmission over mobile nodes. Mobile ad hoc networks are not so resilient and reliable because of their dynamic topology due to the mobile nodes and impact of environmental circumstances. However, it provides multiple routes from the source to the destination, which gives extra redundancy for video and data transmission. In this research work, I will analyze the effect of real video streaming in virtual simulation environment using mobile ad hoc network, terrain modeling module and the System-in-the-loop modules from the OPNET modeling tool

Anomaly Detection Algorithms and Techniques for Network Intrusion Detection Systems

In recent years, many deep learning-based models have been proposed for anomaly detection. This thesis presents a comparison of selected deep autoencoding models and classical anomaly detection methods on three modern network intrusion detection datasets. We experiment with different configurations and architectures of the selected models, as well as aggregation techniques for input preprocessing and output postprocessing. We propose a methodology for creating benchmark datasets for the evaluation of the methods in different settings. We provide a statistical comparison of the performance of the selected techniques. We conclude that the deep autoencoding models, in particular AE and VAE, systematically outperform the classic methods. Furthermore, we show that aggregating input network flow data improves the overall performance. In general, the tested techniques are promising regarding their application in network intrusion detection systems. However, secondary techniques must be employed to reduce the high numbers of generated false alarms
