Android based energy aware real-time location tracking system

Mobile devices are common and mobile internet access is increasingly possible everywhere in daily life of modern people. Commonly used mobile operating systems are Android, iOS and Windows. Android stands out with its open source nature and working capabilities on inexpensive mobile devices. Real-time location tracking is continuously monitoring a vehicle or a person by using obtained coordinates with GPS, Wi-Fi or Cell-Id. Considering that the client person uses mobile phone with internet on it, location tracking can be done with a mobile application. Therefore, using GPS sensor suffers from rapid energy consumption. This paper presents design and implementation of an android based energy aware real-time location tracking system (EWAREL) using GPS sensor. Its hybrid positioning technique employs other inertial sensors and data sending mechanism for saving energy to be efficient. Introduced EWAREL is a lifesaving application especially for real-time monitoring elderly people suffering from Alzheimer's. Alzheimer's people are monitored with EWAREL application and are prevented from being lost. EWAREL is ready to be generalized for other scenarios such as other health monitoring applications, giving direction, monitoring and directing of field staff.
