WebSocket in real time application

Abstract

There has been an increase in request for real time data feeds, teleconferencing and group communication which entails full duplex connection amongst client and server. Real time web application involves clients which is also known as a browser getting updates from the server as they happen. with regards to the limit observed in old-style real-time communication which include long polling, polling server-sent events and comets, this paper recommends using upcoming Web Socket technology when dealing with real time. The Web Socket offers improved result as compared to the conventional approaches that are considered to be the good solution of providing real time information and lessens overhead acquired while communicating over the internet and offers stateful, efficient communication among Web Servers and Clients. A request is initiated by an HTTP client and in which a Transmission Control Protocol (TCP) connection is established [2]. After the client's request has been received, a response is sent back by the server and thereafter the connection is terminated. Using this model, real time data cannot be sent by servers to clients. Consequently, Technologies like Ajax long polling and comet have been used to accomplish real time communication between server and client. Still, real time communication cannot be accomplished in these technologies because some of them needs plugin to be installed on browser which put heaven burden on the server. Real time data communication was achieved with the advent of Web socket protocol and HTML 5. WebSocket description depicts an Application Programming Interface which allow the use of web socket protocol by a web page for two-way communication alongside a remote host [3]. Thus, the HTTP solution can simulate the real time communication with high tag in price, increased network traffic and increased latency. The results to act out the full duplex connection were un scalable polling and long polling methods. WebSocket offers the incredible reduction in the quantity of latency and network traffic in communication system. The WebSocket is quicker than these old-fashioned solutions. LITERATURE REVIEW 2.1 Internet ProtocolInternet protocol suite encompass completely different communication protocols that work over the web and different remote communication networks, and it move (from one place to another) most of the extremely important services which run over the network. It offers end-to-end connectivity by establishing, maintaining, and releasing connections among the sender and receiver. Routing of network, IP addressing, error management and flow management is also delivered by the internet protocol [4]. 1real Time Web DefinitionSynchronous communication system also known as real-time communication system always includes a large number of passive recipients [5].

IoT Based Real-Time Weather Monitoring System Using Telegram Bot and Thingsboard Platform

“…People's daily routines are moving to the virtual world, where people can work, buy, and communicate while living in reality, as communication and internet technology advance quickly. Ogundeyi and Banjo [17] developed the water level and precipitation system observation. The device can detect rain and water levels in functional testing and has relatively high accuracy because it follows the design.…”

Optimisasi Pengecekan Anomali pada Proses Job: Analisis Waktu dan Data untuk Identifikasi Anomali yang Efisien

“…XYZ Tbk yang membutuhkan proses transfer data secara real-time untuk memantau identifikasi, penulis mengajukan WebSocket sebagai metode transfer data secara real-time. WebSocket menawarkan hasil yang lebih baik dibandingkan dengan pendekatan konvensional yang dianggap sebagai solusi dalam menyediakan informasi secara real-time serta menawarkan komunikasi yang cepat dan stateful antara server dan pengguna web (Ogundeyi & Yinka-Banjo, 2019). Secara dasar, dengan menggunakan WebSocket, pengguna dapat menerima data dari server tanpa perlu melakukan permintaan data terlebih dahulu, berbeda dengan Ajax yang hanya dapat menerima data saat pengguna sudah melakukan permintaan kepada server terlebih dahulu (Maulana, 2021).…”

Design and Implement Video and Chat Application Using Mesh Network

“…As well as, the application's usage of continuous polling has the potential to increase communication overhead. Accordingly, using the WebSocket protocol offers a full-duplex bi-directional channel that is accomplished with a single socket, it enables a robust real-time online application [20]. Based on the mentioned connected opinions; understandably chat and video applications are requested.…”
