MES: a system for location-aware smart messaging in emergency situations

Location is considered the most significant element of context in ubiquitous computing. Location information, besides system context information, can offer rich queries for handling information especially in emergency systems. This paper introduces the Mona Emergency System that uses context information in providing emergency services such as sending warning messages to an identified location. MES context information includes actor, danger and point of interest information. This paper describes the MES methodology to obtain and distribute warning messages during emergency situations. MES is a new approach that defines message targets and content using spatial relations.
