Millimeter-wave technology is expected to be able to satisfy these demands and complement the highly congested wireless networks operating in the sub-6 GHz band. However, real-world experimentation with millimeter-wave communications is not always feasible due to the significant amount of resources required and its associated costs. For these reasons, researchers resort to high fidelity system-level simulators which provide a high degree of flexibility to test complex network deployments with a reasonable level of abstraction at the physical layer. The ns-3 IEEE 802.11ad model allows researchers to study large-scale wireless networks operating in the 60 GHz band, taking into account all of the essential features supported by the standard. However, the beamforming capabilities in the current implementation still lack both the flexibility and the agility that commercial of-the-shelf devices offer. Additionally, the model relies on a simplified channel model that does not accurately reflect the characteristics of a millimeter-wave channel. In this paper, we augment our ns-3 IEEE 802.11ad model with novel features that enhance its fidelity and provide the user fine grained control over physical and MAC layer aspects of 802.11ad devices. These features include beam codebooks, multi-antenna beamforming training, beam refinement and beam tracking capabilities, and a quasi-deterministic channel model. Our work paves the way for a future implementation of the next generation wireless gigabit standard, IEEE 802.11ay.","PeriodicalId":166981,"journal":{"name":"Proceedings of the 2019 Workshop on ns-3","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131455563","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}

Network emulation is an important feature in ns-3 and can be used to validate its models by comparing the emulation results to those obtained from real testbeds. Typically, ns-3 uses raw sockets of host's kernel stack to support network emulation. However, there is an active interest to enhance ns-3's network emulation features by using kernel bypass libraries. Recently, a new network device called NetmapNetDevice has been proposed for ns-3 to enable its interaction with netmap. In this paper, we extend network emulation support in ns-3 by using Data Plane Development Kit (DPDK). DPDK provides a set of fast packet processing libraries to bypass host network stack and obtain a direct access to Network Interface Card (NIC). We propose a new network device in ns-3 called DpdkNetDevice, intermediating between ns-3 Internet stack and DPDK environment to read/write packets from/to the NIC. We validate the working of DpdkNetDevice by performing various experiments and comparing results obtained from it to those obtained from EmuFdNetDevice and NetmapNetDevice. We observe that network emulations using DpdkNetDevice on a Gigabit Ethernet NIC provide higher throughput with significantly lesser CPU cycles per packet.","PeriodicalId":166981,"journal":{"name":"Proceedings of the 2019 Workshop on ns-3","volume":"99 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123398053","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}

In this work (a continuation of U. Washington efforts), we present improved physical layer abstractions for a key component underlying all 802.11 WLAN MAC performance evaluation - the Clear Channel Assessment (CCA) procedure central to CSMA/CA - for implementation in the ns-3 simulator. We model the preamble correlation process as typically implemented in 802.11 radio and represent the resulting probability of detection as a look-up table with a parameterized correlation threshold for different receive sensitivity strategies. Further, we also added a new carrier sense threshold adjustment mechanism to allow nodes to enable bypassing the default (and to date, fixed) -82dBm threshold. Such a capability aligns ns-3 for performance evaluation of dense networks equipped with new spatial reuse mechanisms. We demonstrate this via simulation of spatial reuse gains from dynamic sensitivity control (DSC) that are verified against IEEE 802.11ax standards group contributions. Using simulation results from a fixed rate multi-BSS network, we then identify valuable design guidelines to maximize the aggregate throughput with DSC.","PeriodicalId":166981,"journal":{"name":"Proceedings of the 2019 Workshop on ns-3","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129089265","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}

It aims at overcoming some of the shortcomings of TCP, while maintaining the logic related to flow and congestion control, retransmissions and acknowledgments. It supports multiplexing of multiple application layer streams in the same connection, a more refined selective acknowledgment scheme, and low-latency connection establishment. It also integrates cryptographic functionalities in the protocol design. Moreover, QUIC is deployed at the application layer, and encapsulates its packets in UDP datagrams. Given the widespread interest in QUIC's flexibility and features, we believe that it is important to provide to the networking community an implementation in a controllable and isolated environment, i.e., a network simulator such as ns-3, in which it is possible to test QUIC's performance and understand design choices and possible limitations. Therefore, in this paper we present a native implementation of QUIC for ns-3, describing the features we implemented, the main assumptions and differences with respect to the QUIC Internet Drafts, and a set of examples.","PeriodicalId":166981,"journal":{"name":"Proceedings of the 2019 Workshop on ns-3","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130041485","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}
