Nonconcurrent error detection and correction in fault-tolerant discrete-time LTI dynamic systems
(2003)This paper develops resource-efficient alternatives to modular redundancy for fault-tolerant discrete-time (DT) linear time-invariant (LTI) dynamic systems. The proposed method extends previous approaches that are based ...

Nonconcurrent Error Detection and Correction in Fault-Tolerant Linear Finite-State Machines
(2003)In this paper, we construct fault-tolerant linear finite-state machines (LFSMs) in which error detection and correction can be performed nonconcurrently (e.g., periodically). More specifically, by jointly choosing the state ...

On the competitiveness of scheduling dynamically injected tasks on processes prone to crashes and restarts
(2015)To identify the tradeoffs between efficiency and fault-tolerance in dynamic cooperative computing, we initiate the study of a task performing problem under dynamic processes' crashes/restarts and task injections. The system ...

On the robustness of (semi) fast quorum-based implementations of atomic shared memory
(2008)This paper studies a trade-off between fault-tolerance and latency in implementations of atomic read/write objects in message-passing systems. In particular, considering fast or semifast quorum-based implementations, that ...

Performing dynamically injected tasks on processes prone to crashes and restarts
(2011)To identify the tradeoffs between efficiency and fault-tolerance in dynamic cooperative computing, we initiate the study of a task performing problem under dynamic processes' crashes/restarts and task injections. The system ...

Perimeter-based data replication in mobile sensor networks
(2009)This paper assumes a set of n mobile sensors that move in the Euclidean plane as a swarm. Our objectives are to explore a given geographic region by detecting spatio-temporal events of interest and to store these events ...

Periodic and non-concurrent error detection and identification in one-hot encoded FSMs
(2004)State-transition faults in digital sequential systems, such as finite-state logic controllers, have traditionally been handled by embedding the given system into a larger one, in a way that preserves the state evolution ...

Reliably executing tasks in the presence of untrusted entities
(2006)In this work we consider a distributed system formed by a master processor and a collection of n processors (workers) that can execute tasks

Using request queues for enhancing the performance of operations in smart homes
(2012)Modern houses and buildings are being equipped with embedded wireless sensors and actuators, offering advanced automation possibilities. Embedded technology is becoming mature, forming an enticing option for real-life ...
