Abstract
A packet delivery method for assuring the delivery of packets in an wireless local area network (LAN) having a service access point (AP) and a plurality mobile user devices, said user devices in communication with each other and with the access point. The access point determines when a destination device is in the sleep mode of operation and stores data packets intended for that device in memory. Thereafter the access point determines when the destination device enters the active mode of operation, delivers the data packets to the destination device and informs the source device of delivery of the data packets to the destination device.
