HORST - Home router sharing based on trust

Michael Seufert, Valentin Burger, Tobias Hossfeld
2013 Proceedings of the 9th International Conference on Network and Service Management (CNSM 2013)  
Results from different related works suggest that there is a high potential of reducing load on the mobile networks by offloading data to WiFi networks, thereby improving mobile users' quality of experience  ...  Therefore, we propose home router sharing based on trust (HORST) -a socially-aware traffic management solution which targets three popular use cases: data offloading to WiFi, content caching/prefetching  ...  The OSN may also provide geo-location information about the users which allows for recommendation of nearby shared WiFi access points of trusted users, and prediction of content request locations.  ...
