Abstract
A method that does not rely on signal strength for detecting the presence of a broken optical wireless link. The method controls the packet transfer rate in a manner that minimizes both network overhead and computational requirements. Upon completion of the acquisition process, the control packet transfer rate is significantly reduced, since a high control packet transmission rate is only necessary during the acquisition process in order to expedite the acquisition process. The need for reacquisition is based, for example, on the number of consecutive missing packets, or the rate of missing versus received packets.
