Extensions to ANSAware for advanced mobile applications

Abstract

Significant advances have been made in recent years in tackling the problem of heterogeneity in distributed systems with ISO/ITU-T standards for a Reference Model for Open Distributed Processing (RM-ODP) now approaching international agreement. It is important, however, that such standards and related technologies are responsive to new developments in computer and communications technologies. This paper reports on experiences of using the RM-ODP based platform ANSAware in the development of mobile applications to support field workers in the electricity industry. A number of extensions to ANSAware are described including QoS-managed bindings, an enhanced trading service and a new communications protocol. These extensions are evaluated against the requirements of mobile applications.
