Abstract
To reduce interference and increase battery life, a method and apparatus for transmitting location data within an ad-hoc communication system is provided herein. During operation, a portion of a beacon payload is reserved to broadcast location information (coordinates) for a node as well as other parameters that may be needed for location estimation. In addition to a node's location, an accuracy of the nodes location is also included within the beacon field. Because nodes will no longer have to awake outside their beacon transmit times to broadcast location information, battery life is extended. In addition, because nodes will no longer be transmitting location information outside their guaranteed time slot, system interference is also reduced.
