HorNet: Microblogging for a Contributory Social Network
Found in: IEEE Internet Computing
By Daniel Lázaro Iglesias,Joan-Manuel Marquès,Guillem Cabrera,Helena Rifà-Pous,Albert Montané
Issue Date:May 2012
pp. 37-45
Online social networks play an important role in everyday life for many people. However, only a few specialized companies offer services and resources that support social networks. This could expose users to undesired publicity and make them vulnerable to ...
 
Flexible Resource Discovery for Decentralized P2P and Volunteer Computing Systems
Found in: Enabling Technologies, IEEE International Workshops on
By Daniel Lázaro, Joan Manuel Marquès, Xavier Vilajosana
Issue Date:June 2010
pp. 235-240
Resource discovery mechanisms are key for distributed computing. Traditional approaches use dedicated servers to store information about the whole system and make all the scheduling decisions. Many mechanisms exist for decentralized environments, based on ...
 
A Commutative Replicated Data Type for Cooperative Editing
Found in: Distributed Computing Systems, International Conference on
By Nuno Preguica, Joan Manuel Marquès, Marc Shapiro, Mihai Letia
Issue Date:June 2009
pp. 395-403
A Commutative Replicated Data Type (CRDT) is one where all concurrent operations commute. The replicas of a CRDT converge automatically, without complex concurrency control. This paper describes Treedoc, a novel CRDT design for cooperative text editing. An...
 
Design of a Configurable Auction Server for Resource Allocation in Grid
Found in: Complex, Intelligent and Software Intensive Systems, International Conference
By Xavier Vilajosana, Ruby Krishnaswamy, Joan Manuel Marquès
Issue Date:March 2009
pp. 396-401
Large scale systems such as the Grid need scalable and efficient resource allocation mechanisms to fulfil the requirements of its participants and applications while the whole system is regulated to work efficiently. Economics inspired models have shown to...
 
A Best-Effort Mechanism for Service Deployment in Contributory Computer Systems
Found in: Complex, Intelligent and Software Intensive Systems, International Conference
By Daniel Lázaro Iglesias, Joan Manuel Marquès Puig, Josep Jorba Esteve
Issue Date:March 2009
pp. 439-444
This paper presents a simple decentralized service deployment mechanism that can be used to offer services with high availability by using contributed resources with variable, possibly very low availability. It uses little information about the state of th...
 
Information and Regulation in Decentralized Marketplaces for P2P-Grids
Found in: Enabling Technologies, IEEE International Workshops on
By Xavier León, Xavier Vilajosana, René Brunner, Ruby Krishnaswamy, Leandro Navarro, Felix Freitag, Joan Manuel Marquès
Issue Date:June 2008
pp. 133-138
Large scale systems such as the Grid need scalable and efficient resource allocation mechanisms to fulfil the requirements of its participants and applications while the whole system is regulated to work efficiently. Economics inspired models have shown ab...
 
Bidding Support for Computational Resources
Found in: Complex, Intelligent and Software Intensive Systems, International Conference
By Xavier Vilajosana, Joan Manuel Marquès, Ruby Krishnaswamy, Angel A. Juan, Nejla Amara-Hachmi, Leandro Navarro
Issue Date:March 2008
pp. 309-314
The paper presents a bidding specification language and support tools for Grid-oriented open resource marketplaces. The structure of bids is based on trees that permit bidders to express their preferences for Grid resources by means of logical operators. A...
 
An Architecture for Decentralized Service Deployment
Found in: Complex, Intelligent and Software Intensive Systems, International Conference
By Daniel Lázaro, Joan Manuel Marquès, Josep Jorba
Issue Date:March 2008
pp. 327-332
In this paper we present a proposal of the architecture for a system which allows the deployment of services in a group of computers, connected in a peer-to-peer fashion. This architecture is divided in layers, and each of them contains some components whi...
 
Decentralized Service Deployment for Collaborative Environments
Found in: Complex, Intelligent and Software Intensive Systems, International Conference
By Daniel Lazaro Iglesias, Joan Manuel Marques i Puig, Josep Jorba Esteve
Issue Date:April 2007
pp. 229-234
In this paper we present the design of a system which allows service deployment in a small-sized group of computers distributed through the Internet. These groups are formed by users who share a common interest, and voluntarily yield their own resources fo...
 
LaCOLLA: Middleware for Self-Sufficient Online Collaboration
Found in: IEEE Internet Computing
By Joan Manuel Marquès, Xavier Vilajosana, Thanasis Daradoumis, Leandro Navarro
Issue Date:March 2007
pp. 56-64
LaCOLLA middleware makes it possible for collaborators to interact using their own resources without depending on centralized regimes. By contributing their own resources, group members can organize and communicate using a federated peer-to-peer model. Thi...
 
Extending the Scope of Asynchronous Collaboration: A Matter of Being Autonomous and Self-Sufficient
Found in: Enabling Technologies, IEEE International Workshops on
By Joan Manuel Marquès, Leandro Navarro, Thanasis Daradoumis
Issue Date:June 2004
pp. 87-92
Asynchronous collaborative applications and systems have to deal with complexities associated with interaction nature, idiosyncrasy of groups and technical and administrative issues. Inclusion of requirements derived from them is costly (in time, resources...
 
Decentralized resource discovery mechanisms for distributed computing in peer-to-peer environments
Found in: ACM Computing Surveys (CSUR)
By Daniel Lazaro, Joan Manuel Marques, Josep Jorba, Xavier Vilajosana
Issue Date:August 2013
pp. 1-40
Resource discovery is an important part of distributed computing and resource sharing systems, like grids and utility computing. Because of the increasing importance of decentralized and peer-to-peer environments, characterized by high dynamism and churn, ...
