Abstract
A method for sending messages from a particular device to one or more other devices communicants (300) uses the relative geographic location of the targeted devices as addressing criteria. The particular device forms or joins a network of potential communicants, and exchanges information to determine their relative geographic location with respect to that of the particular device (310, 320). The relative geographic location is preferably defined by a directional component and a range component. The communication device then selects for communication those devices that meet specific criteria, such as a specific direction and range, and transmits a message to the selected devices (330, 332, 334, 336).
