Information lookup and distribution in mobile ad hoc networks

Kummer, Raphaël ; Kropf, Peter (Dir.) ; Felber, Pascal (Codir.) ; Konstantas, Dimitri (Codir.) ; Olivera, Rui (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2010.

Dans cette thèse, nous proposons deux nouveaux algorithmes: un algorithme de recherche pour table de hachage distribuée (DHT) et un algorithme construisant des arbres de multicast. Ces algorithmes ont été spécifiquement conçus pour tirer avantage des caractéristiques principales des réseaux mobiles ad-hoc (MANETs) telles que la communication par diffusion, les ressources limitées (en...

Resource Warehouses; a Distributed Information Warehouse Infrastructure

Khoury, Simon ; Kropf, Peter ; Babin, Gilbert

In: Advanced Simulation Technologies Conference (ASTC), 2002, p. 239-244

This paper presents work related to the design of distributed systems, which is useful for emerging Internet applications. We propose algorithms for searching and managing distributed information about resources and services using locally available warehouses. The concept of warehouses has been introduced in the Web Operating System (WOS) (Kropf 1999). Warehouses have the ability to decide which...

On non-intrusive workload-aware database replication

Narváez, Vaide ; Pedone, Fernando (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2009 ; 2009INFO002.

Performance and high-availability are the crucial factors in the development of nowadays distributed database systems. Both of these challenges are commonly addressed by means of the same technique, database replication. The overall throughput of the system is increased by leveraging parallel computation on different sites, and in case of replica failures, availability is improved by...
