Abstract
A system and method for data transmission incorporating a hybrid automatic repeat request (ARQ) function at each node in an ad-hoc network. Each node is configured to calculate an optimum segment size for transmission and thereafter executes the ARQ function to transmit and receive data segments with forward error correction and error detection coding. The coding allows the node to detect and locate errors within received segments and to provide an acknowledgement only after all segments are correctly received. A negative acknowledgement from the receiving node states the location of failed segments, and only failed segments are then retransmitted. The failed segments can be retransmitted in their original location and in other segment locations which contained segments that did not fail, thus reducing maximum time to successfully deliver the segments.
