The creation of digital twins of experimental testbeds allows the validation of novel wireless networking solutions and the evaluation of their performance in realistic conditions, without the cost, complexity and limited availability of experimental ...
IEEE WLANs in 5 vs 6 GHz: A Comparative Study
US Federal Communications Commission (FCC) has adopted new rules to open the 6 GHz bands for unlicensed access as the increasing demand for wireless networks. The new ruling limits operation by a Power Spectral Density (PSD) limit in 6 GHz bands that ...
IEEE 802.11 PSM in ns-3: A Novel Implementation and Evaluation under Channel Congestion
With the proliferation of high-throughput Wi-Fi devices, low-power Wi-Fi enabled devices, such as Internet of Things (IoT) sensors, that generate sparse or sporadic traffic must co-exist in increasingly dense wireless network conditions. A key ...
Integration of WAVE and OpenFlow for Realization of SDN-based VANETs in ns-3
While software defined networking (SDN) has been widely deployed in wired networks within the cloud data centers, its applications with both a wireless control and data channel have not been fully realized. One particular use case is vehicular ad hoc ...
Symbolic ns-3 for Efficient Exhaustive Testing: Design, Implementation, and Simulations
Exhaustive testing is an important type of simulation, where a user exhaustively simulates a protocol for all possible cases with respect to some uncertain factors, such as all possible packet delays or headers. It is useful for completely evaluating ...
Revitalizing ns-3’s Direct Code Execution
This paper reports on significant updates that were made to ns-3’s Direct Code Execution (DCE) feature to restore its compatibility with modern Linux distributions and kernel stacks. Recent versions of the GNU C standard library introduced security ...
Clipping for Faster Wireless Network Simulation in ns-3
In this work we present the concept of ‘clipping’, scheduling receive events for wireless transmissions only on receivers within some distance of the transmitter. Combined with spatial indexing, this technique enables faster simulation of large-scale ...
From LENA to LENA-NB: Implementation and Performance Evaluation of NB-IoT and Early Data Transmission in ns-3
With the growing Internet of Things, more small devices require internet connections. To address the scaling number of Internet of Things devices, Narrowband Internet of Things is enhanced with new features for more efficient transmission of small ...
A Sigfox Module for the Network Simulator 3
In recent years, Sigfox has earned a prominent place in the Low-Power Wide-Area Network arena, attracting the attention of industry, academia, and standards development organizations. As sensors and actuators used in the Sigfox devices aim to be ...
Implementation of mmWave-energy Module and Power Saving Schemes in ns-3
Next-generation 5G New Radio (NR) cellular networks operating at mmWave frequencies are targeted to support diverse use cases, such as enhanced Mobile Broadband (eMBB), massive machine-type communications (mMTC), ultra-reliable and low latency ...
ns3-fl: Simulating Federated Learning with ns-3
In recent years, there has been a spike in interest in the field of federated learning (FL). As a result, an increasing number of federated learning algorithms have been developed. Large-scale deployments to validate these algorithms are often not ...
Evaluation of Reinforcement-Learning Queue Management Algorithm for Undersea Acoustic Networks Using ns-3
Addressing quality-of-service (QoS) requirements for software applications in undersea acoustic networks is challenging. This is in part due to the strong dependency of the characteristics on the acoustic propagation environment and the lack of ...
Artificial Intelligence in Vehicular Wireless Networks: A Case Study Using ns-3
Artificial Intelligence (AI) techniques have emerged as a powerful approach to make wireless networks more efficient and adaptable. In this paper we present an ns-3 simulation framework, able to implement AI algorithms for the optimization of wireless ...
Evaluating OSPF Convergence with ns-3 DCE
OSPF routers flood link-state packets to distribute the network topology. When a link fails, the attached routers flood an updated link-state packet. These packets trigger updates to the forwarding tables of potentially all routers inside the network. ...
Enabling NGMN Mixed Traffic Models for ns-3
The recent advances in cellular network technologies allow serving mixed traffic applications with quality-of-service guarantees. Thanks to it, new applications are gaining a lot of momentum, like gaming, video streaming, and web browsing, among ...
