Avoiding Spurious TCP Timeouts in Wireless Networks by Delay Injection

Overview The Transmission Control Protocol (TCP) has been designed to provide reliable transport of packets by adjusting the transmission rate to the network congestion level. While TCP can adapt to small fluctuations in the delay between the sender and the receiver, adverse affects (most importantly spurious timeouts) have been observed under large delay variability. This paper exhibits the presence of such delay spikes in wireless networks and discusses their possible origins. Then it investigates a new methodology for avoiding spurious TCP timeouts by appropriately injecting additional random delay along the communication path.
