Abstract
Tracking a person problem in a specific city and knowing his geographic location is a big issue. When we know the location of a specific person, we can solve a lot of problems related to security and emergency. On the other hand the introduction of Internet of Things (IoT) is considered as the key infrastructure in a smart city. Therefore we present in this paper a Person Tracking System using the concept of Internet of Things based on Arduino Microcontroller and GPS/GSM/GPRS technologies. Our approach follows an active tracking mode where GPS coordinates are stored in a remote database periodically after a specified time interval. A supervisor can view locations in through web application based on Google Map.
