An Integrated WWAN-WLAN Link Model in Mobile Hotspots

In this paper, we propose a two-state Markov chain to approximately model the packet loss process in mobile hotspots. We consider an integrated wireless wide area network (WWAN)-wireless local area network (WLAN) link in mobile hotspots. Using the Markov chain, we derive expressions of the experienced packet loss probability and packet loss burst length. To verify the accuracy of our analysis, we compare analytical and simulation results, and conclude that an adaptive approach should be deployed to improve the performance of mobile hotspots.
