Over recent years, in order to assist the evaluation, construction, and upgrade of communication networks, the need for the simulation of complex communication networks has increased. Traffic modeling has had a very large impact on network simulation reliability, which is usually statistically described for simulation purposes. Most often, the network traffic analysis isbased on the captured packets. However, modeling of network traffic is usually described by statistics of data sources, from higher layers of a Transmission Control Protocol/Internet Protocol (TCP/IP) model. For these reasons, we have developed a method that allows distribution parameter estimation of the data-source process from captured packets. This method is based on the algorithm, which mimics defragmentation as opposite to the TCP/IPfragmentation and encapsulation processes. The proposed method achieves an accurate description of network traffic.

COBISS.SI-ID: 14478358This paper presents a monitoring of water leakage form the hydro-power plant canal using Synthetic Aperture Radar (SAR) and Ground Penetrating radar (GPR) data. The SAR based monitoring considers soil moisture estimation and moisture detection using Fourier descriptors. The GPR based automatic data interpretation uses the Fourier descriptors for detection of potential water leakage within the canal. The second and fourth order spectral moments, cepstrum, spectral entropy and centroid were used for detection of potential wet areas using SAR and GPR data. The experimental results showed that the SAR data can be used for detection of water leakage, when the surface is already wet, meanwhile the GPR data can be used for determine the water leakage location inside the canal. The GPR measurements were taken on the crone or top of the canal, as well as at the side of the canal. The acquired data were analyzed using Fourier descriptors. Fourier descriptors show good detection of potential wet areas within SAR and GPR data.
F.23 Development of new system-wide, normative and programme solutions, and methods
Manual performance evaluation of tactical communication networks, using OPNET Modeler simulation results, is a very time-consuming task, which also needs a high degree of expert operational knowledge. The developed expert system, with the help of a knowledge base, will automate this process and suggest steps for solving the communication problems of tactical networks. Developed expert system for tactical network evaluation is, in combination with Tactical player, a solution, which offers a deeper understanding of simulation results for a specific planned tactical mission. This leads to a development of better and more reliable tactical networks, which play a critical role in military operations.
