On the Use of ON/OFF Traffic Models for Spatio-Temporal Analysis of Wireless Networks

摘要

The spatial and temporal distribution of active users across a given region greatly affects the activity of base stations (BSs) and the cumulative interference in a wireless network. In this letter, we propose a new approach for spatio-temporal analysis of wireless networks wherein stochastic geometry is used for the spatial domain and ON/OFF traffic models are used for the temporal domain. We illustrate the proposed approach through a mix of file transfer protocol (FTP) and video streaming (VS) traffic. With the aid of semi-Markov process, we derive the stationary probability for a given service request. Further, we develop a joint spatio-temporal model for the distribution of active users under a random BS.
