A conceptual framework for small WSN configuration using intelligent decision support system

A novel intelligent decision support system (IDSS) based on policy settings is proposed in this paper. This work supports the design and configuration of small wireless sensor networks (WSN) used to supply real time environmental and context related data to emergency response applications specifically in the domain of civil defense. This integrated system is advocated to enhance the quality and the scope of automated individual and group decision making in emergency preparedness and response applications. The conceptual framework is firstly presented after a brief definition of the problem and requirements. Then the solution developed for the design and configuration of the WSN is succinctly described. It consists of eliciting the sensing requirements translated into the homogenous sensor node specifications, localizing these sensor nodes using a preplanning process and configuring them prior to their deployment. The configuration characteristics of the homogenous and heterogeneous sensor nodes are presented in terms of policy settings for the definition of the WSN architecture. Results from the case study are finally presented to illustrate the implementation of the solution in emergency preparedness for fire detection.
