Video Conference is an interactive telecommunication technology or system utilizing the internet network so that it is able to interact with audio video with two or more people without considering the distance or different locations, but video conference requires a stable internet network in accordance with the parameters set by Telecommunications and Internet Protocol Harmonization Over Networks (TIPHON) and to determine the quality of video conference can use Quality of Service (QoS). The purpose of this study is to determine delay, throughput, jitter, and packet loss and if someone is doing video conference services on the network, their use can be further enhanced through QoS than other users who only do ordinary internet services (browsing, chatting, etc.) on the network the same network. Here the author uses the Quality of Service (QoS) method as a regulator of internet bandwidth to maximize the use of video conferencing services so that they can run stably when the flow of internet traffic is quite dense. The results of this study are based on the standard TIPHON calculation using the QoS method in testing more or less affect the quality of the video conference service with the evidence in the packet loss recorded at the time of upload and download, mostly touching the 0% figure compared to without using QoS. That way using the help of the QoS method can increase the level of quality and effectiveness in conducting video conference services.

The demand for multimedia services i.e. audio, video and data with improve QoS and optimum utilization of resources in WSN’s has posed new challenges. As the intensity of traffic increases; it demands for higher bandwidth and dedicated resources to reduce packet loss and delay. There have been analytical models proposed where priorities were assigned to video and voice packets to reduce packet loss and optimize resource utilization. In this paper distributed scheme is proposed to handle video, voice and data packets by having multiple sink nodes. There are shared sink nodes where video, voice and data packets are serviced and dedicated sink nodes only for video and voice packets. The proposed scheme has shown that the packet loss for data packets is higher than voice and video packets. The simulation results show that the performance of the network is improved when priorities are assigned to video and voice packets by giving dedicated resources.
