Adjourn state concurrency control avoiding time-out problems in atomic commit protocols
(2008)The use of atomic commit protocols in mobile ad-hoc networks involves difficulties in setting up reasonable timeouts for aborting a pending distributed transaction. This paper presents the non-blocking Adjourn State, a ...

Analyzing the number of slow reads for semifast atomic read/write register implementations
(2009)Developing fast implementations of atomic read/write registers in the message passing model is among the fundamental problems in distributed computing. Typical implementations require two communication round trips for read ...

Blocking reduction for distributed transaction processing within MANETs
(2009)Atomic commit protocols for distributed transactions in mobile ad-hoc networks have to consider message delays and network failures. We consider ad-hoc network scenarios, in which participants hold embedded databases and ...

Brief announcement: On the robustness of (semi)fast quorum-based implementations of atomic shared memory
(2008)Atomic (linearizable) read/write memory is a fundamental abstractions in distributed computing. Following a seminal implementation of atomic memory of Attiya et al.[6], a folklore belief developed that in messaging-passing ...

Cover-ability: Consistent versioning in asynchronous, fail-prone, message-passing environments
(Institute of Electrical and Electronics Engineers Inc., 2016)An object type characterizes the domain space and the operations that can be invoked on an object of that type. In this paper we introduce a new property for concurrent objects, we call coverability, that aims to provide ...

Fault-tolerant semifast implementations of atomic read/write registers
(2009)This paper investigates time-efficient implementations of atomic read-write registers in message-passing systems where the number of readers can be unbounded. In particular we study the case of a single writer, multiple ...
