Abstract
Abstract According to the principles of the invention, there is provided a system, apparatus, and method for conserving energy in a mobile station ( 100 ) of an ad hoc wireless data network ( 10 ). Information concerning motion of the mobile station is obtained, and a rate of motion is used to adjust network parameters such as a beaconing rate ( 202 ) and a link change granularity ( 216 ). These parameters may be adjusted to reduce network overhead transmissions, and the power usage associated therewith, at appropriate times. In one embodiment, network-related transmissions, such as beacon signals and link state announcements, are reduced when the mobile station is moving quickly.
