This document talks briefly about making the current P- Grid implementation secure. We realize the following two requirements which we feel are essential for making communication on P-Grid the most secure one. ...
Message-based communication offers potential benefits of providing stronger specification and cleaner separation between components. Compared with shared-memory interactions, message passing has the potential disadvantages of being more expensive (no direc ...
Within only a couple of generations, the so-called digital revolution has taken the world by storm: today, almost all human beings interact, directly or indirectly, at some point in their life, with a computer system. Computers are present on our desks, co ...
The paper addresses the cost of consensus algorithms. It has been shown that in the best case, consensus can be solved in two communication steps with f < n/2, and in one communication step with f < n/3 (f is the maximum number of faulty processes). This l ...
Classic Paxos is a round-based distributed consensus algorithm. Normally, proposals are sent to the round leader and decided in two communication steps more. Fast Paxos extends Classic Paxos by allowing also fast rounds, in which a decision can be learned ...
We consider large sensor networks where the cost of collecting data from the network nodes to the data gathering sink is critical.~We propose several algorithms that use limited local communication and distributed signal processing to make communication mo ...
Group communication provides one-to-many communication primitives that simplify the development of highly available services. Despite advances in research and numerous prototypes, group communication stays confined to small niches. To facilitate the accept ...
The communication shows an alternative for introducing soil-structure interaction in the analysis of cut-and-cover tunnels. An uncoupled method is illustrated through two examples representative of the situations found in practice. The main features of eac ...
ELU-ULS 2006 - Symposium international sur les états limites ultimes des ouvrages géotechniques2006
Network information theory explores the fundamental data transport limits over communication networks. Broadcasting and relaying are two natural models arising in communication contexts where multiple users share a common communication medium. Number of re ...
This technical report describes the advancements on our research on collaborative annotations of maps. Particularly, we are trying to answer the following research question: does making explicit the location references of the elements of a discourse enhanc ...
