Abstract

By using current positions or predictions of future positions of mobile wireless communication devices, the performance of an ad hoc mesh network is improved. Current positions and predictions of future positions can be used to determine when to set up communication channels between devices. Current and future positions can be determined by the use of a Global Positioning System (GPS) Receiver or other position-determining devices. The GPS Receiver uses signals received from Satellites to determine current position, velocity and acceleration of a mobile wireless communication device. The predictions using current position, velocity and acceleration can be further improved by using devices that “know” the final destination or route of the mobile wireless communication device. An example of such a device would include, but not be limited to, automobile navigation systems that use internal maps and GPS Receivers to guide a driver to a final destination.
