Dynamically tuning a timer mechanism according to radio frequency conditions

A computerized method for dynamically tuning a timer mechanism based on a calculated probability of packet-loss, wherein the method comprises:

• transmitting one or more data packets to a destination device;
• enumerating the one or more transmitted data packets in a recorded history;
• receiving one or more requests from the destination device to retransmit at least one data packet that the destination device ascertains to be missing;
• enumerating the one or more received requests in the recorded history;
• calculating a probability of packet-loss utilizing information within a rolling timeframe of the recorded history;
• dynamically tuning a time-interval of the timer mechanism in a source device by enlarging the time-interval to invoke retransmission of the at least one missing data packet when the probability of packet-loss is calculated to be increased and contracting the time-interval to invoke retransmission of the at least one missing data packet when the probability of packet-loss is calculated to be decreased, wherein the timer mechanism, upon elapse of the time-interval, invokes retransmittal of the one or more data packets;
• and
• relaying instructions to the timer mechanism to start the tuned time-interval upon receiving the one or more requests from the destination device.

A computer system for performing a process that dynamically tunes a timer mechanism based on transmitted data packets and requests for retransmission of those data packets that are received out of order, the computer system comprising a processing unit coupled to a computer storage medium, the computer storage medium having stored thereon a plurality of computer software components executable by the processing unit, the computer software components comprising:

• a sending component configured to transmit the data packets to a receiving component based on a predefined ordering, and to enumerate the transmitted data packets in a recorded history;
• and
• the receiving component configured to detect and assemble the transmitted data packets, and to communicate the requests for retransmission of a portion of the data packets that are received out of order in comparison against the predefined ordering, wherein the sending component is further configured to calculate a probability of packet-loss utilizing the recorded history in concert with the requests for retransmission;
• a timer mechanism configured with a time-interval that is capable of being dynamically tuned by enlarging the time-interval to invoke retransmission of the at least one missing data packet when the probability of packet-loss is calculated to be increased and contracting the time-interval to invoke retransmission of the at least one missing data packet when the probability of packet-loss is calculated to be decreased, wherein, upon elapse of the time-interval, the timer mechanism is further configured to invoke the source device to retransmit the data packets.
