Many distributed systems face the problem of load imbalance between machines. With the advent of Big Data, large datasets whose values are often highly skewed are produced by heterogeneous sources to be often processed in real time. Thus, it is necessary to be able to adapt to the variations of size/content/source of the incoming data. In this...

Hash functions are at the heart of data insertion and retrieval in DHT-based overlays. However, a standard hash function destroys the natural ordering of data. To perform efficient range queries processing, in a minimum number of hops, more and more systems opt for an order-preserving hash function to place data. Unlike a standard hash...

Storing highly skewed data in a distributed system has become a very frequent issue, in particular with the emergence of semantic web and Big Data. This often leads to biased data dissemination among nodes. Addressing load imbalance is necessary, especially to minimize response time and avoid workload being handled by only one or few nodes. Our...

Stocker des informations du web sémantique implique d'être capable de pouvoir potentiellement gérer de très importants volumes de données. D'où le besoin d'opter pour une solution forcément distribuée, entre autres de type pair-à-pair, pour pouvoir passer à l'échelle. Un système de stockage RDF réparti requiert de mettre en place un algorithme...
