%X <p>DHT systems are structured overlay networks capable of using P2P resources as a scalable platform for very large data storage applications. However, their efficiency expects a level of uniformity in the association of data to index keys that is often not present in inverted indexes. Index data tends to follow non-uniform distributions, often power law distributions, creating intense local storage hotspots and network bottlenecks on specific hosts. Current techniques like caching cannot, alone, cope with this issue. We propose a distributed data structure based on a decentralized balanced tree to balance storage data and network load more uniformly across hosts. The results show that the data structure is capable of balancing resources, in particular when performing.</p>
