Energy Efficient Dynamic Navigation System

In the recent years there is considerable growth in the Vehicular system, driver safety and assistance system. In the current trend, Global positioning system (GPS) is one such system used for navigation assistance. Cell phone has become a part and parcel of many people in the world today. If both cell phone and GPS receiver are operational, it leads to increase in the cost and energy of navigation. The main objective of this work is to reduce the cost and minimize the amount of energy consumed in the navigation system. In this paper we propose, an energy efficient, high accuracy, low cost navigation system architecture for the dynamic navigation using the existing infrastructure. It has three techniques for accessing location maps for the navigation system namely; (1) uses reservoir as the source of location maps for cell phone (without Internet connection). It uses cell phone as interface between the navigation system and the reservoir. (2) It is assumed that some of the vehicles in Vehicular Adhoc Network (VANET) have location information. In this case cell phone is used as an interface between VANET and navigation system for transmission of location map and (3) cell phone uses Internet as the source of location maps and transfers location map to the navigation system. Proposed navigation system comprises of memory, Graphical User Interface (GUI), audio/visual system and short range Radio Frequency(RF) communication system.
