Performance improvement of TCP on a wireless ad hoc network

We describe a new technique for improving TCP performance in an ad hoc network that uses a table-driven type of routing protocol paying attention to short-duration link failure. We took as the object of research a flexible radio network (FRN), which is an ad hoc network for data collection. We also evaluated the case in which the effect of the collision of a data packet and an ACK packet is suppressed by delayed ACK and resending the ACK packet preferentially. We showed through simulation the combination of these improvements could increase TCP throughput about 20%.
