LBGR: A LOAD BALANCING P2P FILE STORAGE SYSTEM BASED ON GROUPING AND REPUTATION

The expansion of the Internet leads to the rapid growth of information, which brings about urgent needs for rapid, efficient and reliable mass storage systems. In this paper, we present LBGR, a load balancing P2P file storage system based on grouping and reputation. LBGR evaluates a node by calculating its reputation value, and adopts a mechanism based on grouping and virtual node to solve the load balance problem which exists in distributed hash table structured systems. In LBGR, groups can balance their loads according to their capacities by migrating virtual nodes. The experimental results show that the presented load balance algorithm works well, and is comparable with the centralized algorithm, while it requires less load information of the system.
