The TCP performance degrades significantly in mobile ad hoc networks due to the packet losses. Most of these packet losses result from the route failures due to network mobility. TCP assumes such losses occur because of congestion, thus invokes congestion control mechanisms such as decreasing congestion windows, raising timeout, etc, thus greatly reduce TCP throughput. However, after a link failure is detected, several packets will be dropped from the network interface queue. TCP will time out because of these packet losses, as well as for acknowledgement losses caused by route failures.
