However, such technology migration can potentially induce severe interference to the devices and networks originally operating on unlicensed bands, especially to the Wi-Fi network. In this paper, first of all, we emulate the coexistence of LTE-U networks and Wi-Fi networks, and experimentally evaluate their mutual interference relying on deploying time division duplex based OpenWrt wireless routers. Moreover, an LTE-U and Wi-Fi coexistence mechanism is proposed, where users with diverse traffic demands are capable of accessing either the public LTE-U network or its nearby Wi-Fi network. Finally, an access point selection algorithm with the aid of coalition formation game is developed for improving the system's throughput. Sufficient simulations based on Network Simulator 3 demonstrate that the overall throughput of the LTE-U and Wi-Fi hybrid cosystem outperforms that of the single LTE-U network as well as of the single Wi-Fi network. %G English %L hal-01807290 %U https://centralesupelec.hal.science/hal-01807290 %~ SUP_LSS %~ SUP_SIGNAUX %~ CENTRALESUPELEC %~ LANEAS %~ UNIV-PARIS-SACLAY %~ CENTRALESUPELEC-SACLAY %~ GS-ENGINEERING %~ GS-COMPUTER-SCIENCE
