The emerging high-rate wireless personal area network (WPAN) technology, currently being developed by IEEE 802.15.3 task group, will provide a very high-speed and short-range transmission capability with QoS provisions. Its standard defines three acknowledgement (ACK) types at the MAC layer: no ACK, immediate ACK, and delayed ACK. Those ACK policies, however, do not consider the status of the transmission link, and it may cause overhead by unnecessary ACK frames or fail to maintain the MAC error control. In this paper, we propose an efficient way of MAC acknowledgement which dynamically adjusts the ACK policy according to the link status: A poor link quality causes frequent ACK frames and a good link reduces the number of ACKs. Extensive simulation results show that our method significantly improves the energy efficiency of the WPAN than the standard way of acknowledgement.
