A hierarchical overlay structure is an alternative solution that integrates existing and future heterogeneous wireless networks to provide subscribers with better mobile broadband services. Traffic loss performance in such integrated heterogeneous networks is necessary for an operator's network dimensioning and planning. This paper investigates the computationally efficient loss performance modeling...
Recent developments and technological advances in information and communication technologies are leading to an increasing availability and functionality of portable devices, with improved QoS (Quality of Service) of wireless connections together with decreasing costs. As a consequence, the power consumption of the portable device and the required transmission bandwidth are rapidly increasing. This...
Performance modeling is important for the purpose of developing efficient dimensioning tools for large complicated networks. But it is difficult to achieve in heterogeneous wireless networks, where different networks have different statistical characteristics in service and traffic models. Multiservice loss analysis based on multi-dimensional Markov chain becomes intractable in these networks due...
