EVALUATION OF VOICE TRANSMISSION QUALITY IN THE LTE NETWORKS
Information and Telecommunication Sciences, 2021 Background. LTE mobile networks combine packet network technology and radio technology. Parameters of packet and radio subsystems significantly affects the quality of all traffic types transmission, especially telephone traffic, as the most demanding to ...

On the complexity of QoS routing
Computer Communications, 2003 We present SAMCRA, an exact QoS routing algorithm that guarantees to find a feasible path if such a path exists. Because SAMCRA is an exact algorithm, its complexity also characterizes that of QoS routing in general. The complexity of SAMCRA is simulated in specific classes of graphs.

Improving Quality of Service Routing in Mobile Ad Hoc Networks Using OLSR [PDF]
Journal of Advances in Computer Engineering and Technology, 2015 Mobile ad hoc networks (MANET) are constructed by mobile nodes without access point. Since MANET has certain constraints, including power shortages, an unstable wireless environment and node mobility, more power-efficient and reliable routing protocols ...

QoS to QoE Mapping Function for Iptv Quality Assessement Based on Kohonen Map: A Pilot Study
Transport and Telecommunication, 2020 This paper deals with an analysis of Kohonen map usage possibility for real-time evaluation of end-user video quality perception. The Quality of Service framework (QoS) describes how the network impairments (network utilization or packet loss) influence ...

Electronic Notes in Theoretical Computer Science, 2006 AbstractWe introduce a simple graph logic that supports specification of Quality of Service (QoS) properties of applications. The idea is that we are not only interested in representing whether two sites are connected, but we want to express the QoS level of the connection.

QoS impact on user perception and understanding of multimedia video clips
, 1998 The widespread and increasing advent of multimedia technologies means that there must be a departure from the viewpoint that users expect a Quality of Service (QoS) which will only satisfy them perceptually. What should be expected of multimedia clips is
