MicroJIAC 2.0 - The Agent Framework for Constrained Devices and Beyond. MicroJIAC 2.0 is a matured version of a JAVA-based agent framework born and raised in a diploma thesis. Its development followed a bottom up approach starting with resource constraint devices. Consequently MicroJIAC is also usable on more capable devices. Experiences from projects using the framework lead to modifications of the basic concepts. All derived requirements could be met while retaining the broad field of application.
