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-to-many (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 Emergency Intercom System (EIS) is a communication and video conferencing system designed to enhance emergency response in areas, such as malfunctioning lifts.

With the use of AI algorithms, the exam process is tracked in real time, and each student receives a thorough report. Additionally, the mobile companion app improves the assessment process's integrity by acting as an additional monitoring tool and giving a side view of the student during the test. This article describes the architecture, functionality, and use of the AI-Proctored Exam Portal and its accompanying mobile application, emphasizing the platform's effectiveness in guaranteeing transparent and equitable testing in the online learning environment.
India ranks among the top countries experiencing worst traffic congestion in the world. According to the reports, in India it takes more than 400 minutes to reach a hospital for every second heart ...attack patient which is almost 13 times more than the ideal time of 30 minutes. The primary aim of this proposed solution is to minimize the response time of ambulances approaching the needy. Our proposed approach of the 'One-Tap-Button' emergency response app provides just one 'SOS' (Save Our Souls) button which sends the location of the user to the nearest hospital or medical center within a definite range set in the app via a library called socket.io. The location with the notification mentioning the details of the patient/victim is viewed in the integrated Google Maps app interface. A GPS (Global Positioning System) modem fitted in the ambulance which is responsible for keeping live track of their location by the servers i.e., the hospital's portal. WebRTC (Web Real-Time Communications) live video streaming feature enables direct patient-doctor communication during emergencies, facilitating real-time audio and video transmission. This seamless integration enhances emergency response and prompt healthcare communication.
Lawyer and client relationship is more of a professional relationship. The relationship is developed in a case through mutual communication or connection between client and lawyer. To make the ...communication better and easier, we want to create a virtual platform. The existing platforms only shows lawyers details, previous cases which helps clients to contact them through other media like telephone, or email. These platforms only show their profile from their own viewpoint. There is no opportunity for clients to see the original picture or compare among lawyers. It is also difficult to find the lawyer who is the most suitable for client's case. Our platform aims to solve this problem by creating a platform where lawyers will be able to show their profile, cases and clients can compare among those to find the most suitable lawyer for his or her case. A user can register as a Lawyer or a client in the system using an email address. The registration will be verified by an admin who will act as a super user of the system. Lawyer and client can also monitor meeting schedule, case date, latest findingsto keep themselves updated with each other. Client can easily find lawyer's location using Google Maps. Client can also easily get appointment from the lawyer. Lawyer and Client can also conduct their meeting through video chat using the platform which lessens the hassle of physical meeting and also helpful in any kind of pandemic period. Client can also make payment through the platform which will make the transaction easier.
