5G mobile networks are envisioned to substantiate new vertical services with diverse performance requirements. Slicing in the radio access network (RAN) promises an efficient solution for these diversified needs of networks, which foresees separation base station functionality between central unit (CU) and distributed remote heads. In this article, we formulate a mixed integer programming (MIP)...

In this paper, we propose a single hidden layered fuzzy neural algorithm, which is able to provide a better quality of service constraints in a multi-cell scenario with three different radio access technologies (RATs) namely the Universal Mobile Telecommunication Systems (UMTS), the Wireless Local Area Network (WLAN) and the Global System for Mobile Telecommunication (GSM) / Enhanced Data rate ...

The information and communication technology (ICT) sector is continuously growing, mainly due to the fast penetration of ICT into many areas of business and society. Growth is particularly high in the area of technologies and applications for communication networks, which can be used, among others, to optimize systems and processes. The ubiquitous application of ICT opens new perspectives and e...

This paper presents a system for automated diagnosis of problems in a cellular network, which comprises a method and a model. The reasoning method, based on a naive Bayesian classifier, can be applied to the identification of the fault cause in GSM/GPRS, 3G or multi-systems networks. A diagnosis model for GSM/ GPRS radio access networks is also described, whose elements are available in the net...

Provision of Quality of Service (QoS) guarantees for multimedia applications over IP networks is rapidly becoming a critical research and design issue, especially within the radio access segment of the next generation wireless/mobile environment. While the simple and scalable Differentiated Services (DiffServ) QoS control model is suitable for the core part of the network, more explicit, admiss...

Heterogeneous wireless networks expand the network capacity and coverage by leveraging the network architecture and resources in a dynamic fashion. However, the presence of different communication technologies makes the Quality of Service (QoS) evaluation, management, and monitoring of these networks very challenging. Each communication technology has its own characteristics while the applicati...
