Design and Implementation for Child Tracking System using GPS and WiFi under Android Environment

Recently feature phones are being replaced by smartphones. Because smartphones have various sensors, there are many applications and research works that utilize them. Very few feature phones have GPS modules but all smartphones are equipped with a GPS sensor. One of the hot issues for smartphone research and development is point interest research. In this paper, we will develop an application which protects children using GPS and WiFi.. If a child gets out of the interest-area which is established by parents or guardian, our system sends them messages.
