Abstract

Voice over IP is becoming an important application for wireless networks based in the IEEE 802.11 standard, but many problems must be addressed for the success of this combination, such as providing high number of connections with acceptable speech quality and minimal level of security. This paper presents the results related with a QoS evaluation tool implementation and its utilization in a VoWLAN environment in order to evaluate the performance of the VoIP system with the IPSec used to guarantee confidentiality. In addition, we demonstrate how this QoS tool can be deployed inside the network operation to assist network nodes on selecting more accurate IPSec parameters to reduce the security impact on the real-time traffic
