This paper provides a preliminary experience of the constructing small Barabàsi—Albert model (BA-Model)-based networks that is calculated on multiple web browsers. Our study focuses on a web-based virtual world. In the virtual world, a user requires the other user’s location for communication among multiple users. Our system shares the user’s location by using a BA model-based network. When a new user joins the network, the web server calculates the probability that the new user connects to the other users. This calculation becomes a large workload for the web server by increasing the number of users. In this paper, our system divides the network into some small BA Model-based network, and the role of the constructing networks is delegated to some web browsers. The web server decides which network a new user should join, then the web browser that has responsible for the network determines the users the new user should connect with. By delegating the responsibility of the network construction to web browsers, it is expected that the web server workload will be reduced.
