SOA context-aware mobile data model for emergency situation

At present, the number of mobile device users are increasing as a result of many factors such as today's efficiency of mobile data exchange, the collaboration and support from several business services such as bank system, retail marketing, healthcare, emergency service and etc. Emergency situation is a crisis that needs rapid information retrieval in real time from heterogeneous data source. The appropriate data from multiple data models needs to be chosen for responding in sudden time. However, mobile devices have limitation on memory, battery life time and downlink/uplink bandwidth. Therefore, this paper presents a mSOA (mobile Service Oriented Architecture) data model for emergency environments that based on many factors such as emergency location, emergency type, approximate time when the emergency happened, the patient information and etc.
