A dynamic delayed ACK control scheme on MobilelP networks

摘要

During TCP'IP communications, MobilelP routing optimization functions may transmit out-of-order TCP packet sequences. To solve this problem, we propose a dynamic delayed ACK control scheme in which the wireless link-state management part notifies the upper TCP IP layer of base-station hand-over, and at this time the TCP'IP layer sends dynamic delayed ACKs in response by using two-level-timer (i.e., hard-timer and soft-timer) processing. Simulation results confirm that applying dynamic delayed ACK control to MobilelP networks improves average throughput.
