The techniques to achieve data consistency using operational transformation approach to support real-time and non-real-time collaborative editing are discussed. A proposed collaborative editing prototype system called Adaptive Collaborative Editing (ACE) helps in demonstrating the adaptive data consistency management, adaptive logical time-stamping and adaptive notification. The collaborative environment enables computer-based collaboration in wide-area network. The main objective of a collaborative environment is to allow coherent and consistent object sharing and manipulation by distributed users.
Grid computing presents a new trend to distributed computation and Internet applications, which can construct a virtual single image of heterogeneous resources, provide uniform application interface and integrate wide...

The grid execution management for legacy code architecture (GEMLCA) describes a solution for exposing and executing legacy applications through an OGSI grid service. This architecture has been introduced in a previous paper by the same authors where the general concept was demonstrated by creating an OGSI/GT3 version of the MadCity traffic simulator. The class structure of the architecture is described presenting each component and describing the relationships between them. Also, the current architecture implementation is evaluated through test results gained by running the MadCity traffic simulator as a C/PVM legacy application.

Modelling and simulation permeate all areas of business, science and engineering and increasingly complex simulation systems often require huge computing resources and data sets that are geographically distributed. The widely adopted platform for building distributed simulations is the High Level Architecture (HLA). Deficiencies associated with HLA have been well discussed in the literature. The advent of Grid technology enables the use of distributed computing resources and facilitates the access of geographically distributed data. In this paper, we propose a framework for executing large-scale distributed simulations using Grid services. The framework addresses some of the deficiencies of HLA, including dynamic discovery and resource utilization. End-users can construct large-scale distributed simulations using this framework with ease.

Multiagent systems provide a valuable tool for handling increasing software complexity and supporting rapid and accurate problem solving. This paper presents a general architecture in which autonomous agents are embedded in a distributed virtual environment and are enabled to communicate with each other. We focus on the interaction issues, using cooperation and coordination patterns. Different cases of the agents' teamwork to improve their efficiency are investigated and compared. A prototype system has been implemented, with message templates and algorithms identified. Finally, some experimental results are given.

Summary form only given. Mobile ad hoc networks (MANET) and the Internet exhibit differences in their network architecture. These differences concern the various sorts of assumptions imposed not only on the structure and topology of the underlying networks, but also on communication patterns of mobile nodes in both networks. Integrating MANET and the Internet into a hybrid network is a challenging problem due to these differences. We propose a three-layer approach that uses both mobile IP and dynamic destination-sequenced distance vector (DSDV) to integrate these two types of networks into a hybrid environment, in order to provide MANET nodes with Internet connectivity and access to the Internet resources. Our approach is based on the use of mobile gateways as an interface between MANET and the Internet. These mobile gateways can use mobile IP when they communicate with the Internet and DSDV when they interact with MANET. We also show the results of several simulation experiments that were conducted to study the integrated environment.
