Abstract:
In this paper, an approach to the simulation of peer-to-peer (P2P) live streaming network is presented. The simulation model considers peers’ geolocation and their daily activity, time lags between the video server and a peer, lags between peers, collisions, and three types of selection strategies: neighbor selection strategy, peer selection strategy and chunk selection strategy. Geolocation is considered as distribution of users by time zones and the users' daily activity is defined as the distribution of the number of online users by the hour of the day. Initial data for the geolocation of users and their daily activity are taken from known Internet sources. The aim of this study is to show how the parameters of the geolocation and users’ daily activity affect the performance of the network. To do this, we compare the download probability obtained analytically without geolocation and daily activity with the results of simulation. Preliminary numerical analysis carried out for the case of the Rarest First chunk selection strategy, shows difference in results of up to 30%.
