Significant advances have been made in recent years in tackling the problem of heterogeneity in distributed systems with ISOl 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 QoSmanaged
bindings, an enhanced trading service and a new communications protocol. These
extensions are evaluated against the requirements of mobile applications.
