Pusher-watcher: An approach to fault-tolerant tightly-coupled robot coordination
, 2001
"... We present a distributed planar object manipulation algorithm inspired by human behavior. The system, which we call pusher-watcher, enables the cooperative manipulation of large objects by teams of autonomous mobile robots. The robots are not equipped with gripping devices, but instead move objects ..."

Fault-Tolerant Clock Synchronization for Embedded Distributed
, 2002
"... Embedded computer control systems become more and more common for different functional tasks in cars, airplanes, and factory automation systems. In addition, systems for different functional tasks become interconnected and system functions more integrated. As a consequence, these systems become larg ..."

larger and more complex. Multi-cluster systems are a way to structure large distributed systems to manage complexity and overcome communication bandwidth limitations. A cluster is a system where nodes are tightly coupled and are connected via direct communication links. Nodes of different clusters
Fault-Tolerant Distributed Applications in LiPS
- Hochschule Darmstadt, FB Informatik
, 1996
"... Performing computations using networks of workstations is increasingly becoming an alternative to using a supercomputer. This approach is motivated by the the vast quantities of unused idle-time available in workstation networks. Unlike computing on a tightly coupled parallel computer, where a fixed ..."

This paper shows how fault-tolerant distributed applications are implemented within LiPS version 2.4, a system for distributed computing using idle-cycles in networks of workstation. This system currently is used at the Universitat des Saarlandes in Saarbrucken to perform
A Scalable Byzantine Fault Tolerant Secure Domain Name System
, 2001
"... The domain name system is the standard mechanism on the Internet to advertise and access important information about hosts. At its inception, DNS was not designed to be a secure protocol. The biggest security hole in DNS is the lack of support for data integrity authentication, source authentica ..."

As a solution, we present the design and implementation of a Byzantine-fault-tolerant domain name system. The system

Lock-free parallel algorithms: An experimental study
- In Proceedings of the 11th International Conference High Performance Computing
, 2004
"... Abstract. Lock-free shared data structures in the setting of distributed computing have received a fair amount of attention. Major motivations of lock-free data structures include increasing fault tolerance of a (possibly heterogeneous) system and getting rid of the problems associated with critical ..."

Building Multirobot Coalitions Through Automated Task Solution Synthesis -- A group of robots can move to, or push boxes to, specified locations by sharing information when individual robots cannot perform the tasks separately
, 2006
"... This paper presents a reasoning system that enables a group of heterogeneous robots to form coalitions to accomplish a multirobot task using tightly coupled sensor sharing. Our approach, which we call ASyMTRe, maps environmental sensors and perceptual and motor control schemas to the required flow ..."

Through combining the logic programming language Prolog with a data driven execution mechanism we may be closer to solving the problems encountered when designing tightly coupled multiprocessors involving more than a trivial number of processor elements.

Database replication based on group communication, or simply GCS-based database replication, has recently been the focus of much attention as a promising technology to achieve strong consistent large-scale data management. GCS-based database replication is expected to provide increased dependability ..."

Software Architecture Patterns for Distributed Embedded Control Systems
"... Abstract. Embedded systems are often tightly coupled with their environment, implying specific requirements – such as distribution, real-time, and fault toler-ance – to software, to be taken into account in the design of software architecture. Yet, there is little systematic support for designing su ..."
