ABSTRACT:
This invention provides a method of transmitting and receiving packets containing data and positional information for a plurality of devices in a radio frequency network in combination with a global positioning system. The periodic position coordinates of each said device are determined using the global positioning system. The position coordinates are transmitted from each device at staggered points in time that are randomized, and the randomizing operation is performed in discrete steps, wherein the time period of each discrete step is of adequate duration for one device to transmit a positional update. A positional update table and proximity table is created and maintained for each device, and these tables are transmitted to every other device in the network at periodic intervals.
