Abstract
WLP(WiMedia Logical link control Protocol) is a protocol to support IP services on the WiMedia UWB platform. It defines that DRP needs to be employed using TSPEC parameters when the packets from upper layer transmit with QoS. However, there is no appropriate means to provide QoS when the TSPEC of the traffic is unknown. In this paper, we propose TSPEC estimation scheme to provide QoS for such unknown applications by monitoring the traffic in realtime. Also, the scheme to estimate the effective TSPEC is proposed that compensate the packet losses in the wireless environment to provide the required QoS. The performances of the proposed TSPEC estimation schemes are evaluate by simulation assuming random wireless packet loss and 1mm-ACK mechanism.
