Abstract
To enable seamless integration of ad hoc networks with other Infrastructure LANs and to the Internet, TCP seems to be the natural choice for users of ad hoc networks that want to communicate reliably with each other and with the Internet. It is well-known that due to the nature of multi-hop wireless Ad hoc network applications, TCP throughput instability can have a devastating impact on the QoS requirements and is regarded as one of the main TCP problems. In this paper, we first illustrate the TCP throughput instability simulation results for a chain-topology network that uses the IEEE 802.11 medium access control protocol and ad hoc routing protocol. We then discuss why the performance of TCP is poor in this scenario. A simple solution is proposed that enables the DSR routing protocol to reduce its trigger of unnecessary route error process due to MAC collisions which interrupts and affects the TCP link operation …
