Since WLAN and 3G connectivity might exhibit disparate round-trip times, transmission control protocol (TCP) connections can be affected as a result of a flow handover.
From the simulations of some existing high speed protocols, we observe that these high speed protocols make the round-trip time bias problem and the multiple-bottleneck bias problem more serious than for standard TCP.
For the stop-and-wait ARQ protocol, the round-trip time (RTT) is a key factor to measure the communication efficiency and effective throughput.
Nevertheless, in practice, the PTE can also be calculated in a way that is similar to the way the round-trip time is estimated in network transport protocols to allow the PTE adapt to sample variance more quickly.
While a majority of related authentication protocols are based on measuring the round-trip distance between prover and verifier using several single-bit challenge response pairs, recent discussions include physical proximity verification using ambient conditions to address relay attacks.
a Round-trip time constitution of the traditional stop-and-wait ARQ protocol.
Indoor positioning is also getting a boost in Android P thanks to support for the IEEE 802.11mc protocol, which provides information about Wi-Fi round-trip time, which in turn allows for relatively accurate indoor positioning.
The main problem with DTNs is that existing networking protocols in use today, such as the ubiquitous TCP/IP protocols, assume the availability of an end-to-end path and acceptable round-trip times in communication.
With the use of Real Time Control Protocol (RTCP) signaling, the source node collects the feedback information about the round-trip time from the destination.
Based on this methodology, they first show and prove that, independent of any specific MAC layer protocol, the upper bound of a path's BDP cannot exceed its round-trip hop-count (RTHC).
In this context, the upper layer is considered as Internet Protocol (IP) layer of protocol stack, whose performance are normally evaluated by parameters of packet loss rate (PLR), round-trip time (RTT).
