위치기반 에코 내비게이션 서비스를 위한 GPS 수신 기법

초록

Current mobile device technology has evolved to a point where affordable smart-phones with a variety of functions are readily available to the public. The capability of the onboard GPS (Global Positioning System) make them ideal for developing navigation applications, whereby relevant information is communicated to users based on their actively determined location. However, the use of power consuming GPS application on mobile device pose a burden on battery life. Fortunately, it is notable that the users recognize traffic sign themselves and do not always rely on navigation system before routing is required, hence continuous GPS reception is needless. Based on this observation, we propose a location-based eco-navigation method that reduce the frequency of unnecessary GPS reception during inactive routing intervals. Extensive simulation suggests that power consumption decreases about 47% compared to existing GPS reception method.
