Achieving this goal for wideband spectrum and in real-time is a challenging problem. Existing methods are limited to a small bandwidth, and lack the capability to detect and classify multiple RF emissions in every part of a wide spectrum with a unified detection and classification solution. We present WRIST, a Wideband, Real-time RF Identification system with Spectro-Temporal detection,framework and system. Our resulting deep learning (DL) model is capable to detect, classify, and precisely locate RF emissions in time and frequency using RF samples of 100 MHz spectrum in real-time(over 6Gbps incoming I&Q streams). Such capabilities are made feasible by leveraging a deep learning-based one-stage object detection framework, and transfer learning to a multi-channel visual-based RF signals representation. We also introduce an iterative training approach which leverages synthesized and augmented RF data to efficiently build large labelled datasets of RF emissions. WRIST's detector achieves 90 mean Average Precision even in extremely congested environment in the wild. WRIST model classifies five technologies (Bluetooth, Lightbridge, Wi-Fi, XPD, and ZigBee) and is easily extendable to others.","PeriodicalId":349943,"journal":{"name":"Proceedings of the 19th ACM International Symposium on Mobility Management and Wireless Access","volume":"342 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124229972","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}

We look at ways to extend the protocol to support credential provisioning and configuration of new client devices. As large numbers of IoT devices are deployed, the task will be simplified by combining the network connectivity, identity and certificate provisioning, and application-layer connectivity to one process. The solution will also allow the use of a one-time credential for the initial authentication, so that the long-term device certificate is issued automatically after the first connection to the network. The paper analyzes the requirements and architectural design options that implement such a user experience. We consider solutions that transfer short bootstrapping data inside the EAP session and then implement the provisioning and configuration with web APIs over HTTPS. This allows future flexibility and speed of development in the provisioning and configuration steps. We designed and implemented several architecturally different solutions and present the comparison results and also compare with previous proposals that have similar goals.","PeriodicalId":349943,"journal":{"name":"Proceedings of the 19th ACM International Symposium on Mobility Management and Wireless Access","volume":"149 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114636873","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 attributes that set vehicular clouds apart from conventional clouds is resource volatility. As vehicles enter and leave the cloud, new compute resources become available while others depart, creating a volatile environment where the task of reasoning about fundamental performance metrics becomes very challenging. Just as in conventional clouds, job completion time ranks high among the fundamental quantitative performance figures of merit. With this in mind, the main contribution of this work is to offer easy-to-compute approximations of job completion time in a dynamic vehicular cloud model involving vehicles on a highway. We assume estimates of the first moment of the time it takes the job to execute without any overhead attributable to the working of the vehicular cloud. A comprehensive set of simulations have shown that our approximations are very accurate.","PeriodicalId":349943,"journal":{"name":"Proceedings of the 19th ACM International Symposium on Mobility Management and Wireless Access","volume":"148 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133264662","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}

Low-power operation of commercial Wi-Fi enabled IoT modules (typically powered by replaceable batteries) is critical in order to achieve a long battery life, while maintaining connectivity, and thereby reduce the cost and frequency of maintenance. In this work, we focus on commonly used sparse periodic uplink traffic scenario in IoT. Through extensive experiments with a state-of-the-art Wi-Fi enabled IoT module (Texas Instruments SimpleLink CC3235SF), we study the performance of the power save mechanism (PSM) in the IEEE 802.11 standard and show that the battery life of the module is limited, while running thin uplink traffic, to ~30% of its battery life on an idle connection, even when utilizing IEEE 802.11 PSM. Focusing on sparse uplink traffic, a prominent traffic scenario for IoT (e.g., periodic measurements, keep-alive mechanisms, etc.), we design a simulation framework for single-user sparse uplink traffic on ns-3, and develop a detailed and platform-agnostic accurate power consumption model within the framework and calibrate it to CC3235SF. Subsequently, we present five potential power optimization strategies (including standard IEEE 802.11 PSM) and analyze, with simulation results, the sensitivity of power consumption to specific network characteristics (e.g., round-trip time (RTT) and relative timing between TCP segment transmissions and beacon receptions) to present key insights. Finally, we propose a standard-compliant client-side cross-layer power saving optimization algorithm that can be implemented on client IoT modules. We show that the proposed optimization algorithm extends battery life by 24%, 26%, and 31% on average for sparse TCP uplink traffic with 5 TCP segments per second for networks with constant RTT values of 25 ms, 10 ms, and 5 ms, respectively.","PeriodicalId":349943,"journal":{"name":"Proceedings of the 19th ACM International Symposium on Mobility Management and Wireless Access","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130562371","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}

Wireless Mesh Networks (WMNs) using Dynamic Spectrum Access (DSA), such as Television White Spaces (TVWS), create new avenues for research due to the additional constraints and complexity. For the production of controlled and repeatable experiments and design of CA algorithms without the drawbacks and difficulties of real hardware, we use Network Simulator 3 (ns3). In this paper we address the construction of an experimental setup in ns3 for evaluating CA algorithms in a DSA WMN environment. Additionally, we propose a solution to the CA problem in this scenario using Simulated Annealing. We simulate TVWS device operation by adding TVWS channels (this can be extended to include any new DSA bands), provide a framework for multi-radio multi-channel WMN experiments, and present and analyse the performance of a CA algorithm. Results show that the proposed algorithm provides channel assignments with much improved performance (120%-755% better) over random channel assignments.","PeriodicalId":349943,"journal":{"name":"Proceedings of the 19th ACM International Symposium on Mobility Management and Wireless Access","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126871787","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}

However, research and development in this field are hindered because there is a lack of a framework that can be easily extended to collect various types of monitoring data from the WiFi stack. In this paper, we propose FLIP, a framework for leveraging eBPF to augment WiFi access points and investigate the performance of WiFi networks. Using this framework, we focus on two important aspects of monitoring the WiFi stack. First, considering the high delay experienced by packets at access points, we show how switching packets from the wired interface to the wireless interface can be monitored and timestamped accurately at each step. We build a testbed using FLIP access points and investigate the factors affecting packet delay experienced in access points. Second, we present a novel approach that allows access points to track the duty-cycling pattern and energy consumption of their associated stations accurately and without the need for any external energy measurement tools. We validate the high energy measurement accuracy of FLIP by empirical experiments and comparisons against a commercial tool.","PeriodicalId":349943,"journal":{"name":"Proceedings of the 19th ACM International Symposium on Mobility Management and Wireless Access","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126580930","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 includes ranging capabilities based on Fine Timing Measurements (FTM) and can sustain connectivity to a Wi-Fi network while participating in a NAN cluster. Android is currently the only operating system to support it, offering a limited and proprietary interface. NAN shares many fundamental properties with Apple's Wireless Direct Link protocol, which is used by millions of devices today. To facilitate research in this area, we present OpenNAN: the first open source NAN stack. It supports Linux and requires just common and cheap off-the-shelf Wi-Fi hardware. Using OpenNAN we perform a security analysis of NAN and identify three attacks. First, any malicious node can manipulate the Anchor Master Selection to become the Anchor Master. Second, a malicious Anchor Master can desynchronize individual nodes by sending synchronization beacons as unicast. And finally, we show a Machine-in-the-Middle (MitM) on the NAN Service Discovery Protocol. We successfully perform all attacks against different Android versions and NAN stacks.","PeriodicalId":349943,"journal":{"name":"Proceedings of the 19th ACM International Symposium on Mobility Management and Wireless Access","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124769369","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}
