Semantic Driven Self-Adaptation of Communications Applied to ERCMS

To adapt communication in order to maintain the connectivity and the quality of communications in group-wide collaborative activities becomes challenging when considering mobile entities in a wireless environment, requiring responsiveness and availability of the communication system, and designing self-adaptable communication architecture remains a complex task. To simplify this task, semantic presents a very attractive alternative to support self-adaptation and context awareness. This paper proposes three ontologies to model different aspects related to communication (organizational, collaborative and contextual) and to forecast future problems in accordance with priorities. Adaptation actions are also proposed for self-adaptation in communicating architecture. These actions deal with different changing context parameters such as resource constraints and architecture evolution requirements. To illustrate the proposed ontologies and some adaptation actions, we use ERCMS (Emergency Response and Crisis Management Systems) scenarios of the ROSACE project as a case study from the more general group communication systems.
