ABSTRACT:
Methods and apparatus for delivering ordered and duplicate-free wireless data frames are generally described and claimed herein. Other embodiments may also be described herein. In an embodiment, a source address, a destination address, and a message sequence number are acquired from a wireless data frame. The message sequence number is compared against a last-received message sequence number and a last-delivered message sequence number. The destination address is also compared to a current address. In response to the compares, a decision is made to forward the wireless data frame to the destination address, discard the wireless frame as a duplicate wireless data frame, queue the wireless data frame, or release the wireless data frame to a next protocol layer.
