Abstract
A method for locating machines in space, comprises the steps of determining a location of each machine via a global positioning system calculation performed at the machine. The GPS position is used to determining a cell corresponding to the determined location in which the machine is located. Each machine waits for a time slice allocated for the cell to broadcast a message indicative of the machine's position. In turn, the broadcasted messages are received from a plurality of machines and used determine the locations of the plurality of machines.
Claims31
A method for locating machines in space, comprising the steps of:
- at each machine, determining a location of the machine via a global positioning system calculation;
- at each machine, determining a cell corresponding to the determined location;
- at each machine, broadcasting a message at a time slice allocated for the cell;
- and
- receiving broadcasted messages from a plurality of machines;
- and
- using the received broadcasted messages to determine the locations of the plurality of machines.
A system including memory and processor for locating machines in space, comprising:
- at each machine, a global positioning system for determining a location of the machine;
- at each machine, means for determining a cell corresponding to the determined location;
- at each machine, means for broadcasting a message at a time slice allocated for the cell;
- and
- means for receiving broadcasted messages from a plurality of machines;
- and
- means for using the received broadcasted messages to determine the locations of the plurality of machines.
A computer program product in a computer readable medium for locating machines in space, comprising:
- global positioning system instructions for determining a location of the machine;
- means for determining a cell corresponding to the determined location;
- means for broadcasting a message at a time slice allocated for the cell;
- and
- means for receiving broadcasted messages from a plurality of machines;
- and
- means for using the received broadcasted messages to determine the locations of the plurality of machines.
