An asynchronous communication system for pervasive grids
International Journal of Web and Grid Services, 2008Event-driven paradigms have become the leading model for large classes of applications and environments. In particular, pervasive, ubiquitous and grid computing, in which services dynamically plug in and get out, rely on middleware services that use communication channels and events to integrate and coordinate application-level services.

Buffered asynchronous communication mechanisms
Proceedings. Fourth International Conference on Application of Concurrency to System Design, 2004. ACSD 2004., 2004Previous work on asynchronous communication mechanisms (ACMs) has not dealt with buffered forms (n > l). This paper describes a systematic design/synthesis process for ACMs with arbitrary buffer size, a series of resulting buffered ACM algorithms, and the modelling and simulation of these ACMs using Matlab, putting ACMs (esp.

Error correction for asynchronous communication
2016 9th International Symposium on Turbo Codes and Iterative Information Processing (ISTC), 2016We propose a forward error correction scheme for asynchronous sensor communication where the dominant errors consist of pulse deletions and insertions, and where encoding is required to take place in an instantaneous fashion. The presented scheme consists of a combination of a systematic convolutional code, an embedded marker code, and power-efficient ...

Keyless asynchronous covert communication
2016 IEEE Information Theory Workshop (ITW), 2016We consider a scenario in which Alice asynchronously communicates with Bob over a Discrete Memoryless Channel (DMC) while escaping detection from an adversary who observes their communication through another DMC. Specifically, Alice transmits codewords of length n and chooses the transmission epoch T uniformly at random among N available time epochs ...

Error exponents in asynchronous communication
2011 IEEE International Symposium on Information Theory Proceedings, 2011Based on recent work on asynchronous communication, this paper proposes a slotted asynchronous channel model and investigates the fundamental limits of asynchronous communication, in terms of miss and false alarm error exponents. We propose coding schemes that are suitable for various asynchronous communication scenarios, and quantify more precisely ...

New algorithms for asynchronous communication
IEE Proceedings - Computers and Digital Techniques, 1997Concurrent processes are said to communicate asynchronously when there is no mutual timing interference resulting from their communication operations. This property can be achieved by mechanisms which use multiple shared memory locations (slots) to transfer data, and where access to these slots is co-ordinated by small shared control variables ...

An object calculus for asynchronous communication
2006This paper presents a formal system based on the notion of objects and asynchronous communication. Built on Milner's work on π-calculus, the communication primitive of the formal system is purely based on asynchronous communication, which makes it unique among various concurrency formalisms.

Asynchronous health care communication
Communications of the ACM, 2003Patients' desire for online communication with their health care providers is likely to change the course of both telemedicine and e-health technologies.

From Synchronous to Asynchronous Communication [PDF]
, 1990 The design and the verification of distributed systems consisting of communicating processes can be difficult. The task is simpler when the rendezvous mechanism of CSP is used, but this mechanism often leads to rather inefficient implementations. For this reason, an asynchronous communication mechanism is preferred, provided that the correctness of the

Design with Asynchronously Communicating Components
2003Software oriented methods allow a higher level of abstraction than the often quite low-level hardware design methods used today. We propose a component-based method to organise a large system derivation within the B Method via its facilities as provided by the tools.
