MAC-level partial checksum for H.264 video transmission over 802.11 ad hoc wireless networks


We present a technique to enhance real-time video transmissions over 802.11-based ad hoc networks. We propose to limit the coverage of the error detection mechanism to the most error sensitive bit class contained in video packets. Packets are retransmitted only if errors affect those bits, instead of retransmitting all corrupted packets irrespective of… (More)
