“…An example is Multipath TCP (MPTCP), the multipath extension of TCP which makes it possible to transmit data on multiple subflows (i.e., a mobile user could simultaneously transmit on a Wi-Fi subflow and a cellular subflow) [109]. At the time of writing, it was implemented for ns-3 by different projects [110], [111], but none of them is completely compliant with the MPTCP specification, and they are not integrated in the main ns-3 release and validated. With DCE, instead, it is possible to use the MPTCP code developed and tested by the same MPTCP protocol designers [112].…”

Due to its potential for multi-gigabit and low latency wireless links, millimeter wave (mmWave) technology is expected to play a central role in 5th generation (5G) cellular systems. While there has been considerable progress in understanding the mmWave physical layer, innovations will be required at all layers of the protocol stack, in both the access and the core network. Discrete-event network simulation is essential for end-to-end, cross-layer research and development. This paper provides a tutorial on a recently developed full-stack mmWave module integrated into the widely used open-source ns-3 simulator. The module includes a number of detailed statistical channel models as well as the ability to incorporate real measurements or raytracing data. The Physical (PHY) and Medium Access Control (MAC) layers are modular and highly customizable, making it easy to integrate algorithms or compare Orthogonal Frequency Division Multiplexing (OFDM) numerologies, for example. The module is interfaced with the core network of the ns-3 Long Term Evolution (LTE) module for full-stack simulations of end-to-end connectivity, and advanced architectural features, such as dualconnectivity, are also available. To facilitate the understanding of the module, and verify its correct functioning, we provide several examples that show the performance of the custom mmWave stack as well as custom congestion control algorithms designed specifically for efficient utilization of the mmWave channel.This work has been submitted to IEEE Communication Surveys and Tutorials for possible publication.

“…Feng et al 11 have clearly discussed the requirement of higher bandwidth in mobile Internet for flying drones, specifically for blockchain‐based applications. To get around this limitation, an idea of simultaneously using all the active interfaces of SMD without much changing the existing Internet infrastructures has been investigated 1,5,12–16 . All these investigations are the proposals around the use of MPTCP.…”

Summary Today's smart mobile devices (SMDs) are equipped with multiple interfaces, powerful processors, and workable battery power. Such SMDs are making future networks truly heterogeneous. In such future mobile networks, there is an opportunity to utilize the SMD's interfaces concurrently. There are challenges in the implementation of this idea, because regular TCP does not support path aggregation, multihoming, and full‐mesh networking. The multipath TCP (MPTCP) is a power set of TCP extensions that provide the subflows on each SMD's interface. The MPTCP runs over the existing infrastructure of the TCP by using TCP options field, without compromising the normal TCP functions. An end‐to‐end data scheduling and data reordering are important issues in such mobile Internet across multiple subflows of MPTCP. In this paper, we proposed the mechanisms for multipath scheduling, device‐centric data reordering, and buffer management to achieve concurrent utilization of SMD's LTE and Wi‐Fi interfaces for video stream applications on mobile Internet. We modeled the approaches for multipath scheduling and reordering to ensure the improved utilization of SMD's interfaces and decrease the buffer usage. The proposed approaches consider the outstanding data bytes and latency of each MPTCP subflow. The proposed approaches are tested on a MPTCP‐supported testbed, and captured data are analyzed in terms of gross throughput, buffer usage, end‐to‐end performance, and path utilization of subflows on SMD's LTE and Wi‐Fi interfaces. The performance is evaluated and compared with related state‐of‐the‐art approaches, and significant improvement is observed.

“…A significant number of MPTCP research works depend on the ns-3 simulator. In the research articles [ 13 , 14 , 15 , 16 ], the authors propose implementations of MPTCP in ns-3. Some of these MPTCP implementations have been used to study MPTCP performance as in the sequel.…”

The multipath transmission control protocol (MPTCP) is considered a promising wireless multihoming solution, and the 3rd generation partnership project (3GPP) includes it as a standard feature in the fifth-generation (5G) networks. Currently, ns-3 (Network Simulator-3) is widely used to evaluate the performance of wireless networks and protocols, including the emerging MPTCP protocol. This paper investigates the fidelity of the Linux kernel implementation of MPTCP in the ns-3 direct code execution module. The fidelity of MPTCP simulation is tested by comparing its performance with a real Linux stack implementation of MPTCP using a hardware testbed for two different setups. One setup emulates the existence of a bottleneck link between the sending and receiving networks, whereas the other setup does not have such a bottleneck. The fidelity of ns-3’s simulation is tested for four congestion control algorithms, namely Cubic, linked-increases algorithm (LIA), opportunistic LIA (OLIA) and wVegas for relatively short and long data flows. It is found that the uplink MPTCP throughput performance exhibited by the ns-3 simulator matches the hardware testbed results only if the flows are long-lived and share no common bottleneck link. Likewise, the MPTCP throughput achieved during a downlink scenario using the ns-3 simulator and the hardware testbed are close to each other across all algorithms except wVegas regardless of the flow size if there is no bottleneck link. Moreover, it is observed that the impact of LTE handover on MPTCP throughput is less significant in the simulator than the real hardware testbed, and it is setup-dependent.
