QoS based performance analysis of VoWLAN for emergency calls using QualNet

Voice over WLAN (VoWLAN) has been emerging as an infrastructure to provide low-cost wireless voice services. Reaping the profits of voice over WLAN, we can enhance the underlying technologies behind emergency call to improve the QoS parameters. Nowadays, the researchers have been focusing to bring in new technologies like VoIP for variety of applications. Healthcare is one of the major area where emergency calls are extensively required. Hospitals are one of the first users of VoWLAN solutions, mainly because of the significant need for effective communication among high-valued medical staff. In case of a medical emergency, VoWLAN can mean the difference between life and death. The emphasize of the paper is to analyze the resource and cost effective utilization of VoWLAN, particularly for reduced delay based emergency call routing.
