Abstract: Internet is gradually developing from network of computers into a vast network that connects a large number of small intelligent things (Internet of Things). One of the main problems we face with them is that they possess very limited resources. So, they are not able to perform some complex tasks in the form of interactive communication with complex networks and presentation of these data in real time mode. On the other hand, we have a strongly growing technology, the Internet, which has the possibility to distribute an enormous amount of data to anyone, anytime and anywhere (3A) without any problems. The ability to create a network of small, almost invisible sensor nodes, which will continuously collect information from the real world and then this information distributed to a large number of clients around the world, apply this technology unimagined. This paper explores the possibility of implementation of a new technology, the WebSocket protocol, which should reduce the communication traffic between the source and destination, enabling real-time detection of changes, ie. reduce the delay in the transfer of data and thus enable longer life such applications. A critical analysis of the application WebSocket protocol from the viewpoint of exchanged packets as well as the size of headers in these packages, compared to some other solutions ie. protocols for real time communication is done.
