Conference Proceeding: Empirical study of the QoS parameters behavior of a VoIP application in wi-fi networks
[show abstract] [hide abstract]
ABSTRACT: The use of wireless local area networks (WLANs), as well as the proliferation of the use of multimedia applications has grown fast in recent years. Some factors affect the quality of service(QoS) received by the user. The interference is an example. This work presents an empirical study of the QoS parameters of a VoIP application in the presence of an interference network, as well as the relevance in the design of wireless networks to determine the range of an access point, taking into account several parameters as power, jitter, packet loss, delay and PMOS.Microwave and Optoelectronics Conference (IMOC), 2009 SBMO/IEEE MTT-S International; 12/2009 -
Conference Proceeding: A methodology for capacity planning and performance evaluation of wireless networks based on measuring and Bayesian inference: A Brazilian amazon approach
[show abstract] [hide abstract]
ABSTRACT: This paper presents a methodology for capacity planning and performance evaluation based on hybrid approach that considers measuring and Bayesian inference applied to wireless networks, considering QoS parameters. The models take into account a crosslayer vision of networks, correlating aspects of the physical environment, on the signal propagation (power or distance) with aspects of VoIP applications (e.g., jitter and packet loss). A case study is carried out considering indoor environment (research laboratory) and outdoor environment with important characteristics of the Amazon region (e.g., densely arboreous environments).Communications and Networking in China, 2008.
