This topic is old and some of our classmate working on it since 2010. They called coexistence (cognitive) between LTE or WiMax with WiFi. The following are some algorithms research paper:
1)Spectrum Co-existence of IEEE 802.11b and 802.16a Networks Using Reactive and Proactive Etiquette Policies
2) COMPETITIVE POTENTIAL OF WIMAX IN THE BROADBAND ACCESS MARKET: A TECHNO-ECONOMIC ANALYSIS
3)IEEE 802.22: An Introduction to the First Wireless Standard based on Cognitive Radios
Every modern smartphone can do this, simply turn on your hotspot and see the coexistence, finding such an algorithm should not be a research question today. Also check:
