RTP analysis for the video transmission process on WhatsApp and Skype against signal strength variations in 802.11 network environments

Abstract

Today many people communicate using video content over the internet, either one-way, two-way or even multi-way or conference-friendly communication. Skype and WhatsApp are one of them, with a huge number of users around the world. The 802.11 wireless network is still the primary choice to access on the internet, especially for users with indoor mobility. Through the mobile application platform, Skype and WhatsApp service users can move from one place to another. unfortunately, this will create a variation in signal power reception on the device used in the scope of the 802.11 network access point. So in this study, we want to know the response of Skype and WhatsApp application when there is a change of signal strength on 802.11 wireless networks, through analysis of received RTP packets. The data show to us, WhatsApp managed to stream RTP packets of nearly 12 thousand packages, compared to Skype which only revolves around 4800 packages.
