Design and Implement a Hybrid WebRTC Signalling Mechanism for Unidirectional & Bi-directional Video Conferencing

Abstract

WebRTC (Web Real-Time Communication) is a technology that enables browser-to-browser communication. Therefore, a signalling mechanism must be negotiated to create a connection between peers. The main aim of this paper is to create and implement a WebRTC hybrid signalling mechanism named (WebNSM) for video conferencing based on the Socket.io (API) mechanism and Firefox. WebNSM was designed over a combination of different topologies, such as simplex, star and mesh. Therefore it offers several communications at the same time as one-to-one (unidirectional/bidirectional), one-to-many (unidirectional) and many-tomany (bi-directional) without any downloading or installation. In this paper, WebRTC video conferencing was accomplished via LAN and WAN networks, including the evaluation of resources in WebRTC like bandwidth consumption, CPU performance, memory usage, Quality of Experience (QoE) and maximum links and RTPs calculation. This paper presents a novel signalling mechanism among different users, devices and networks to offer multi-party video conferencing using various topologies at the same time, as well as other typical features such as using the same server, determining room initiator, keeping the communication active even if the initiator or another peer leaves, etc. This scenario highlights the limitations of resources and the use of different topologies for WebRTC video conferencing.

“…The HTML language structures the data, the CSS stylizes this data to make them visually comprehensible and aesthetic, the JS (Javascript acronym) allows to produce animations and interactions improving the user experience. The usual components are [4], [8] : a. CSS source code to create a grid: this allows the developer to position the different elements that make up the design of the site in a simple and versatile way. b. Typography style definitions for HTML elements.…”

Performance Evaluation of Resources Management in WebRTC for a Scalable Communication

“…B. An equation of Quality of Experience According to the real-time implementation as mentioned in [14][15] [18], that each peer consumes minimum 950 kb/s and maximum 1350 kb/s for video and between 58-63 kb/s for audio on each RTP (Real Time Protocol) via LAN and WAN networks. Moreover, in the real-time implementation, actual users have participated to give their individual opinions; therefore, the quality of audio and video has been assessed on different CPUs, such as i5, i7 and Xeon.…”

“…This paper gives an extensive explanation to support the concerned developers to get the specifications of WebRTC resources on the scalability and to determine the best topology that can be used in WebRTC bi-directional video conferencing. This implementation used the factors and measurements of real-time implementation as described in [14][15] [18]. This paper is organised and outlined as follows: Section II some WebRTC related work.…”
