1. A method for communicating data between a network and devices of a vehicle, comprising:
- selecting, by a processor, a first timeframe from a plurality of timeframes when vehicle speed is below a speed threshold;
selecting, by the processor, a second timeframe from the plurality of time frames when the vehicle speed is above the speed threshold, wherein the second timeframe is smaller than the first timeframe;
sampling, by the processor, within the selected timeframe a plurality of round trip times associated with the network,determining, by the processor, a minimum round trip time from the plurality of round trip times;
determining, by the processor, a ratio by dividing the minimum round trip time by a current round trip time;
adjusting, by the processor, a size of a window used in communication with the network based on the ratio; and
communicating data between the network and the devices of the vehicle based on the size of the window.

Abstract
Methods and systems for communicating data between a network and devices of a vehicle are provided. A method includes: determining, by a processor, a value associated with a round trip time based on vehicle information; adjusting, by the processor, a size of a window used in communication with the network based on the value; and communicating data at least one of to and from the network based on the size of the window.

11. A system for communicating data between a network and devices of a vehicle, comprising:
a non-transitory computer readable medium, comprising; a first module that selects, by a processor, a first timeframe from a plurality of timeframes when vehicle speed is below a speed threshold, that selects, by the processor, a second timeframe from the plurality of time frames when the vehicle speed is above the speed threshold, wherein the second timeframe is smaller than the first timeframe, that samples, by the processor, within the selected timeframe a plurality of round trip times associated with the network, that determines, by the processor, a minimum round trip time from the plurality of round trip times, and that determines, by the processor, a ratio by dividing the minimum round trip time by a current round trip time; a second module that adjusts, by the processor, a size of a window used in communication with the network based on the ratio; and a third module that, by the processor, communicates data between devices of the vehicle and the network based on the size of the window. - View Dependent Claims (12, 13, 14)
