However, experimentation is limited in aspects where simulation excels, such as repeatability and reproducibility. Real wireless experiments are hardly repeatable. Given the same input they can produce very different output results, since wireless communications are influenced by external random phenomena such as noise, interference, and multipath. Real experiments are also difficult to reproduce due to testbed operational constraints and availability. We have previously proposed the Trace-based Simulation (TS) approach, which uses the TraceBasedPropagationLossModel to successfully reproduce past experiments. Yet, in its current version, the TraceBasedPropagationLossModel only supports point-to-point scenarios. In this paper, we introduce a new version of the model that supports Multiple Access wireless scenarios. To validate the new version of the model, the network throughput was measured in a laboratory testbed. The experimental results were then compared to the network throughput achieved using the ns-3 trace-based simulation and a pure ns-3 simulation, confirming the TS approach is valid for multiple access scenarios too.","PeriodicalId":231834,"journal":{"name":"Proceedings of the 2018 Workshop on ns-3","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132564797","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The standard was only published in May 2017 and hardware supporting Wi-Fi HaLow is not available on the market yet. As such, research on 802.11ah has been mostly based on mathematical and simulation models. Mathematical models generally introduce several simplifications and assumptions, which do not faithfully reflect real network conditions. As a solution, we previously developed an IEEE 802.11ah module for ns-3, publicly released in 2016. This initial release consisted of physical layer models for sub-1GHz communications and an implementation of the fast association and Restricted Access Window (RAW) channel access method. In this paper, we present an extension to our IEEE 802.11ah simulator. It contains several new features: an online RAW configuration interface, an energy state model, adaptive Modulation and Coding Scheme (MCS), and Traffic Indication Map (TIM) segmentation. This paper presents the details of our implementation, along with experimental results to validate each new feature. The extended Wi-Fi HaLow module can now support different scenarios with both uplink and downlink heterogeneous traffic, together with real-time RAW optimization, sleep management for energy conservation and adaptive MCS.","PeriodicalId":231834,"journal":{"name":"Proceedings of the 2018 Workshop on ns-3","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127179866","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the key steps towards this objective is the inclusion of a set of numerologies, which are specified by subcarrier spacing and cyclic prefix. Different numerologies can be exploited to meet different quality-of-service (QoS) requirements in terms of latency and throughput. To achieve this, 3GPP specifies that the NR system shall support multiplexing of numerologies in time and/or frequency domain. In this work, we focus on frequency division multiplexing (FDM) of numerologies. To allow simulation of FDM of numerologies in the ns-3 network simulator, we have extended the mmWave module with some of the key features defined for NR systems. These extensions include support for NR frame structure, numerologies, and on top of that the FDM of numerologies. To implement the FDM of numerologies, we leveraged the carrier aggregation (CA) feature of ns-3 LTE module, and for that purpose, we have extended the mmWave module to support the CA functionality. In this paper, we describe these extensions and we carry out a performance evaluation of numerologies and FDM of numerologies.","PeriodicalId":231834,"journal":{"name":"Proceedings of the 2018 Workshop on ns-3","volume":"2009 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125591515","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are two strategies to generate output from ns-3, either using generic predefined bulk output mechanisms or using the ns-3's Tracing system. Both require parsing the raw output data to extract and process the data of interest to obtain meaningful information. However, parsing such output is in most cases time consuming and prone to mistakes. Post-processing is even harder when a large number of simulations needs to be analyzed and even the tracing system cannot simplify this task. Moreover, results obtained this way are only available once the simulation is finished.Therefore, we developed a user-friendly interactive visualization and post-processing tool for IEEE 802.11ah called ahVisualizer. Beside the topology and MAC configuration, ahVisualizer also plots our traces for each node over time during the simulation, as well as averages and standard deviations for each traced parameter. It can compare all the measured values across different simulations. Users can easily download figures and data in various formats. Moreover, it includes a post-processing tool which plots desired series, with desired fixed parameters, from a large set of simulations. This paper presents the ahVisualizer, its services and its architecture and shows how this tool enables much faster and easier data analysis and monitoring of ns-3 simulations with 802.11ah.","PeriodicalId":231834,"journal":{"name":"Proceedings of the 2018 Workshop on ns-3","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131554606","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
