• Cognitive network model dedicated to transport system telematics

  Publikacja

  • M. Gajewska

  - Archives of Transport System Telematics - Rok 2014

  The paper defines the concept of cognitive radio, in the context of transport systems, with particular emphasis on modern ecological concept of “green cognitive radio”. In addition, in the paper a modified cognitive network model dedicated to transport system telematics is proposed and presented. Algorithms to support the functioning of the cognitive radio are discussed. Sensors necessary to use the network to support cognitive...

• Applying a Mesoscopic Transport Model to Analyse the Effects of Urban Freight Regulatory Measures on Transport Emissions—An Assessment

  Publikacja

  • J. Oskarbski
  • D. Kaszubowski

  - Sustainability - Rok 2018

  Sustainable urban freight management is a growing challenge for local authorities due to social pressures and increasingly more stringent environmental protection requirements. Freight and its adverse impacts, which include emissions and noise, considerably influence the urban environment. This calls for a reliable assessment of what can be done to improve urban freight and meet stakeholders’ requirements. While changes in a transport...

  - Sustainability - Rok 2018

  When planning their transport policy, cities usually focus on developing sustainable transport systems and reducing the negative consequences of transport. One way to deliver transport policies is to use the Sustainable Urban Mobility Plan (SUMP), a strategic document designed to meet the demand for mobility whilst ensuring adequate quality of life for the residents. The process of Sustainable Urban Mobility Planning (SUMP process)...

• Simulation Model of IMS/NGN with Transport Stratum Based on MPLS Technology

  Publikacja

  • S. Kaczmarek
  • Ł. Łuczaj
  • M. Sac

  - Przegląd Telekomunikacyjny + Wiadomości Telekomunikacyjne - Rok 2016

  In the paper we continue our research on traffic modelling in the Next Generation Network (NGN) architecture, which includes the IP Multimedia Subsystem (IMS) elements. A simulation model of a single NGN domain with transport stratum based on the Multiprotocol Label Switching (MPLS) technology is proposed, which allows evaluation of mean response time of this stratum. The simulation model is applied to verify the results obtained...

• Traffic Model of IMS/NGN Architecture with Transport Stratum Based on MPLS Technology

  Publikacja

  • S. Kaczmarek
  • M. Kosek
  • M. Sac

  - International Journal of Electronics and Telecommunications - Rok 2013

  Growing expectations for a fast access to information create strong demands for a universal telecommunication network architecture, which provides various services with strictly determined quality. Currently it is assumed that these requirements will be satisfied by Next Generation Network (NGN), which consists of two stratums and includes IP Multimedia Subsystem (IMS) elements. To guarantee Quality of Service (QoS) all NGN stratums...

• Simulation Model for Application of the SDN Concept in IMS/NGN Network Transport Stratum

  Publikacja

  • S. Kaczmarek
  • M. Sac
  • J. Adrych

  - Rok 2024

  The paper presents a simulation model allowing examination of cooperation between two currently used telecommunication networks concepts: IP Multimedia Subsystem/Next Generation Network (IMS/NGN) and Software-Defined Networking (SDN). Application of the SDN architecture elements in IMS/NGN networks will enable unified control and management of transport resources for various transport technologies and equipment manufacturers. However,...

• Analytical Traffic Model for a Multidomain IMS/NGN Network Including Service and Transport Stratum

  Publikacja

  • S. Kaczmarek
  • M. Sac
  • M. Cieśliński

  - Rok 2022

  This paper addresses the problem of modelling call processing performance (CPP) in a multidomain Next Generation Network (NGN) architecture including the elements of the IP Multimedia Subsystem (IMS) in service stratum and based on the Multiprotocol Label Switching (MPLS) technology in transport stratum. An analytical traffic model for such an architecture is proposed by integrating the formerly implemented submodels of service...

• Controlled Random Search Applied to Parameters Estimation of the Longitudinal Solutes Transport Model for Rivers

  Publikacja

  • T. Dysarz

  - Rok 2003

  Numerical computations are presented for the longitudinal transport of passive, conservative solutes in an actual river with the inclusion of geometrical complexities of river channels. A special emphasis is put on the method of the identification of model parameters which is based on a specially designed optimisation procedure using random control search algorithm. Two different situations are considered namely a linear version...
