P-Grid's a self-organizing structured peer-to-peer system, which can accommodate arbitrary key distributions (and hence support lexicographic key ordering and range queries), still providing storage load-balancing and efficient search by using randomized routing. Salient features Good storage load-balancing despite arbitrary load-distribution over the key-space. Range queries can be naturally supported and efficiently processed on P-Grid because of P-Grid abstracts a trie-structure, and supp… (More on P-grid)
