Agent substitution mechanism for dataflow networks: Case study and implementation in Smart-M3

Abstract

The paper continues the study of dataflow networks based on top of Smart-M3 platform. The goal is to provide support for implementation of reliable ubiquitous services based on the dataflow model. We propose agent substitution as a way to make services robust and describe behaviour and implementation aspects of the agent substitution mechanism in semantic information broker. The mechanism allows to safely transfer computational context from one agent to another preventing long service downtime when an agent unanticipatedly disconnects from the network. The potential benefit of using such a mechanism is discussed for the medical telemonitoring service. © 2013 Springer-Verlag.
