Systems and Methods for Managing Failed Packet Transmissions using a Smart Retransmission Scheme with Hierarchical Packet Analysis

Abstract:

Systems and methods are provided for identifying the true content of a data packet wirelessly transmitted and retransmitted from a first device to a second device. The second device receives an original transmission of the data packet (first packet instance), followed by first and second retransmissions of the data packet (second and third packet instances), thus defining a group of three received packet instances, each including erroneous data. The second device may execute a hierarchical packet analysis algorithm to determine the true content of the transmitted data packet, which includes (a) testing selected pairs of the three packet instances to attempt to determine the true content of the transmitted data packet; and (b) if the pair-wise analysis fails, analyzing the first, second, and third packet instances collectively (triplet analysis) to attempt to determine the true content of the transmitted data packet.
