Practical Method for Emergency Intervention in Smart Cities

Today almost anyone carries at least one mobile phone. Help in case of emergency can be requested by dialing a special number, like 112. A normal emergency call contains the description of the emergency, its localization by communicating the exact address, the caller identification by giving personal information like name, home address etc. The process becomes challenging if the victim panics and cannot clearly communicate verbally or he is unsure about his current location. In the case of robberies, it can be assumed that the attacker would not let the victim perform an emergency call. The paper proposes a practical emergency intervention method to resolve these critical situations for almost everyone. It can help the user communicate its situation and exact location at a touch of a screen and without arousing the suspicion of the aggressors, if it is the case. The complete architecture, procedures and results obtained with the first prototype are presented in the paper.
