Continuous Multi-Way Joins over Distributed Hash Tables
... ABSTRACT This paper studies the problem of evaluating continuous multi-way joins on top of Distributed Hash Tables (DHTs). We present a novel algorithm, called recursive join (RJoin), that takes into ...

Efficient Processing of Continuous Join Queries using Distributed Hash Tables
... In order to assess our approach, we compare the network traffic of DHTJoin against a complete implementation of RJoin [13] which is the most relevant related work (see Section 5). RJoin uses incremental evaluation based ...

Authentication in stealth distributed hash tables
... For example, when a stealth node joins or leaves the network, no service nodes need to update their routing ta- bles, which prevents them from being affected by stealth nodes churning. This is especially important from a ...

Heterogeneity and Load Balance in Distributed Hash Tables
... ID space balance for heterogeneous DHTs. Comparatively few schemes handle node heterogeneity. Dabek et al [9] suggested that each physical node have a number of virtual servers proportional to its capacity, which we have ...

Bounding Communication Cost in Dynamic Load Balancing of Distributed Hash Tables
