Fog Computing is a new way to store data for the Internet of Things. Instead of using a Distributed Hash Table, this study suggests using a tree-based approach to find object replicas faster. By mapping the physical layout of servers, the time to locate an object is reduced by 20%. This method adds location records near object replicas to improve access times and reduce network traffic. The new approach was tested using the InterPlanetary FileSystem on different network topologies, showing an average time of less than 15 ms to find an object.
