ID management method is the foundation to implement and maintain DHT overlays, especially for Constant Degree DHTs based on de Bruijn and Kautz, because their topologies are not incrementally expandable and using bit-shifting route schema etc. However, corresponding researches on Constant Degree DHTs are scarce, and realized Constant Degree DHTs usually use pure centralized or distributed ID management...
DHTs are scalable, self-organizing, and adaptive to underlying topology changes, thus being a promising infrastructure for realizing autonomic communications in distributed systems. To provide the above advantages, however, DHTs sacrifice flexibility, that is, all messages are routed by using a common algorithm in a DHT on the assumption that all participant nodes are homogeneous. In practice, nodes...
DHTs are scalable, self-organizing, and adaptive to underlying topology changes, thus being a promising infrastructure for realizing efficient Web service discovery. Range queries play an important role in service discovery, and in recent years a number of DHT-based range query schemes have been proposed. However, most of them suffer from high query delay and high processing cost. This paper presents...
In most DHTs proposed so far, all nodes are assumed to be homogeneous, and all messages are routed using a common algorithm. In practice, however, nodes in large-scale systems might be heterogeneous with respect to their capabilities, reputations, affiliations of administrative domains, and so on, which consequently makes it preferable to distinguish the heterogeneity of participant nodes. To achieve...
