Gossip, also known as epidemic dissemination, is becoming an in- creasingly popular technique in distributed systems. Yet, it has remained a partially open question: how robust are such protocols? We consider a natural ex- tension of the random phone-call ...

Embedded sensors and actuators are revolutionizing the way we perceive and interact with the physical world. Current research on such Cyber-Physical Systems (CPSs) has focused mostly on distributed sensing and data gathering. The next step is to move from ...
In this paper, we show that distributed systems are vul- nerable to routing attacks and propose an architecture to obviate this vulnerability. A somewhat surprising finding is that even a small-scale routing attack can completely dis- rupt the operation of ...
Fault-tolerant computing is the art and science of building computer systems that continue to operate normally in the presence of faults. The fault tolerance field covers a wide spectrum of research area ranging from computer hardware to computer software. ...
High performance computing will probably reach exascale in this decade. At this scale, mean time between failures is expected to be a few hours. Existing fault tolerant protocols for message passing applications will not be efficient anymore since they eit ...
The last three decades have seen computers invading our society: computers are now present at work to improve productivity and at home to enlarge the scope of our hobbies and to communicate. Furthermore, computers have been involved in many critical system ...
Transportation safety, one of the main driving forces of the development of vehicular communication (VC) systems, relies on high-rate safety messaging (beaconing). At the same time, there is consensus among authorities, industry, and academia on the need t ...
Problems in fault-tolerant distributed computing have been studied in a variety of models. These models are structured around two central ideas: (1) degree of synchrony and failure model are two independent parameters that determine a particular type of sy ...
Group communication in partitionable systems has been the focus of many research activities over the last decade. Fault-tolerant applications in a partitionable system model generally rely on two basic services: a group membership service and a reliable mu ...
