In the times of a disaster, there is a need for coordination of resources and quick response in order to minimize and rectify the damage done. Quick Response Co-ordination System (QRCS) provides a robust, mobile web application architecture to locate, allocate and track resources. It concentrates on quick communication and coordination between the disaster management team and resource handlers for better managing and mapping of resources for faster aid and rescue. A context-aware infrastructure manages the context model representing contextual information and provides appropriate information. In this paper, we introduce Context-Aware Middleware for QRCS as a context-aware infrastructure for a distributed intelligent QRCS and discuss the JSON-based context modeling and reasoning approach which will be used in the infrastructure.
