This paper describes a group communication system called the timewheel group communication system that has been designed for a timed asynchronous distributed system model. The timewheel group communication system consists of three protocols: a clock synchronization, an atomic broadcast protocol, and a group membership protocol. All these protocols have been designed to be fail-aware in the sens...

We introduce dQUOBEC, the event channel communication system used by dQUOB. It is a publish-subscribe system implemented as event channels and uses Portable Binary Input Output (PBIO) for data transfer. It supports typed channels, in that a channel transfers events having the same type. dQUOBEC has been implemented with C++ and provides C++ and Java API for applications. The main features of dQ...

We propose a setup for an odor communication system. Its different parts are described, and ways to realize them are outlined. Our scheme enables an output device-the whiffer-to release an imitation of an odorant read in by an input device-the sniffer-upon command. The heart of the system is the novel algorithmic scheme that makes the scheme feasible. We are currently at work researching and de...

This paper presents an architecture to dynamically change from a given group communication protocol to another. Such an architecture allows a system designer to create a distributed system that takes advantage of the different features of various group communication protocols by selecting the most favorable one under particular circumstances. The system wraps a set of independent group communic...

Abstract: This paper focuses on the various advantages of current mode circuits over the widely used voltage mode circuits in communication system. The individual blocks of a basic communication system are designed in voltage mode and the circuits are then converted into their equivalent voltage mode. Conclusions are drawn based on the various responses observed in both the modes. The existing ...

Ant colony optimization is an ant algorithm framework that took inspiration from foraging behavior of ant colonies. Indeed, ACO algorithms use a chemical communication, represented by pheromone trails, to build good solutions. However, ants involve different communication channels to interact. Thus, this paper introduces the acoustic communication between ants while they are foraging. This proc...

Our journal started six years ago in response to the opinions of many researchers around the globe that there was a need of an on-line, peer reviewed, scholarly journal which could address fundamental issues of electronic commerce research and practice. One reason for this opportunity was the rapid evolution of electronic commerce. The continuing changes in the technological innovations on whic...
