This interest has exacerbated in 2020 and became a vital need during the current global pandemic. However, providing end-users of various educational backgrounds access to radio devices from a heterogeneous set of vendors is challenging. This paper introduces OneLNK, a remotely accessible testbed consisting of radio devices from three different vendors and developed using open source cloud-native technologies. End-users can access the functionalities of OneLNK from a single webpage without any local installations. Using the web URL, users can operate radio devices, set experiment parameters, observe results in real-time, and save generated experiment data for all radio devices. The interactive web UI and its working mechanism for supporting radio equipment are covered with specific experiment capabilities. A diverse set of radio equipment (mmWave, sub-GHz SDR, and sub-6GHz SDR) are facilitated to explain these capabilities. Moreover, measurements of path loss, Received Signal Strength (RSS), and Signal-to-Noise Ratio (SNR) using devices from three different vendors operating on a vast spectrum (568 MHz, 5.8 GHz, and 60 GHz) are reported. The majority of the remotely accessible OneLNK platform was developed remotely during the pandemic by a team of experts from five U.S. states.","PeriodicalId":347962,"journal":{"name":"Proceedings of the 15th ACM Workshop on Wireless Network Testbeds, Experimental evaluation & CHaracterization","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122509489","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 such approach is via Multipath TCP (MPTCP), a transport layer protocol that is transparent to applications and requires no changes to the underlying wireless drivers. However, MPTCP (as well as other bundling approaches) have only been evaluated to date in 60 GHz WLANs with laptop clients. In this work, we port for first time the MPTCP source code to a dual-band smartphone equipped with an 802.11ad and an 802.11ac radio. We discuss the challenges we face and the system-level optimizations required to enable the phone to support Gbps data rates and yield optimal MPTCP throughput (i.e., the sum of the individual throughputs of the two radios) under ideal conditions. We also evaluate for first time the power consumption of MPTCP in a dual-band 802.11ad/ac smartphone and provide recommendations towards the design of an energy-aware MPTCP scheduler. We make our source code publicly available to enable other researchers to experiment with MPTCP in smartphones equipped with millimeter wave radios.","PeriodicalId":347962,"journal":{"name":"Proceedings of the 15th ACM Workshop on Wireless Network Testbeds, Experimental evaluation & CHaracterization","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116750623","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 inherent complexity of the RAN ecosystem and the fact that it is rapidly evolving makes Open RAN a rich area of research into use cases, system realization, security, and more. This same complexity, however, hampers research efforts. Specifically, there is a lack of end-to-end open source software and fully-developed use cases associated with the Open RAN ecosystem. Further, to truly advance the state of the art will require use cases to be explored in realistic wireless environments. This paper describes our efforts to address these shortcomings by realizing NexRAN, a top-to-bottom, open-source Open RAN use case in the POWDER mobile and wireless research platform. Specifically, NexRAN allows closed-loop control of a RAN slicing realization in an O-RAN ecosystem. RAN slicing is implemented in the srsRAN open source mobility stack and is exposed through a custom service model to the NexRAN xApp, which executes on a RAN intelligent controller (RIC) from the O-RAN Alliance. The NexRAN xApp realizes policy driven closed-loop control of RAN slices by reading the current state of RAN elements (using the O-RAN key performance measurements (KPM) service model) and controlling slice behavior via the custom slicing service model. We demonstrate and evaluate NexRAN in the POWDER platform and have open sourced all aspects of our realization to enable research into this domain.","PeriodicalId":347962,"journal":{"name":"Proceedings of the 15th ACM Workshop on Wireless Network Testbeds, Experimental evaluation & CHaracterization","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115936815","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 framework was built on COSMOS, an advanced wireless testbed designed to support real-world experimentation of next generation wireless technologies and applications. Our deployed framework supports experimentation over a large number of wireless networks, with a PUB-SUB based network interaction structure, based on the Collaborative Intelligent Radio Networks (CIRN) Interaction Language (CIL) developed by DARPA for the Spectrum Collaboration Challenge (SC2). As such, it enables interaction and message exchanges between the networks for the purposes of coordinating spectrum use. For our experiment, the message exchanges are aimed primarily for, but not limited to, Spectrum Consumption Model (SCM) messages. RF devices/systems use SCM messages which contain detailed information about their wireless transmission characteristics (i.e., spectrum mask, frequency, bandwidth, power and location) to determine their operational compatibility (non-interference) with prior transmitters and receivers, and to dynamically determine spectrum use characteristics for their own transmissions.","PeriodicalId":347962,"journal":{"name":"Proceedings of the 15th ACM Workshop on Wireless Network Testbeds, Experimental evaluation & CHaracterization","volume":"133 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123761727","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}

When integrating unmanned aerial vehicles (UAVs) into cellular networks, their cell association needs to be carefully managed for coexistence with other cellular users. UAVs move in three dimensions and may traverse several cells on their flight path, and so may be subject to several handovers. In order to enable research on mobility management with UAV users, this paper describes the design, implementation, and testing methodology for handover experiments with aerial users. We leverage software-defined radios (SDRs) and implement a series of tools for preparing the experiment in the laboratory and for taking it outdoors for field testing. We use solely commercial off-the-shelf hardware, open-source software, and an experimental license to enable reproducible and scalable experiments. Our initial outdoor results with two SDR base stations connected to an open-source software core network, implementing the 4G long-term evolution protocol, and one low altitude UAV user equipment demonstrate the handover process.","PeriodicalId":347962,"journal":{"name":"Proceedings of the 15th ACM Workshop on Wireless Network Testbeds, Experimental evaluation & CHaracterization","volume":"390 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122849689","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}

Among the many protocols governing IoT operation, MQTT has seen wide adoption, but comes with rudimentary security support. Specifically, while the MQTT standard strongly recommends that servers (brokers) offer Transport Layer Security (TLS), it is mainly concerned with the message transmission protocol, leaving to implementers the responsibility for providing appropriate security features. However, well-known solutions for Web Security (OAuth2) exist, which may benefit MQTT. This paper presents systematic implementation efforts and practical experimentation to evaluate the feasibility of one such approach, namely the MQTT-TLS profile for the Authentication and Authorization in Constrained Environments (ACE), recently specified by the IETF. Our implementation includes the functionality for (1) the Authorization Server (AS), to handle client registration, authorization policies, and Access Tokens; (2) the MQTT broker, to enforce authentication in both MQTT versions 3.1.1 and 5. Together, these enable ACE-MQTT clients to use (3) OAuth2-based authentication and authorization via Proof of Possession tokens. We make the source-code of our ACE-MQTT implementation publicly available, and evaluate it against plain MQTT systems in realistic settings with different computation constraints. To assess the cost of security, we measure the CPU, memory, network usage, and energy consumption. The results obtained confirm that the ACE requirements match the capabilities of moderately constrained devices, hence providing an affordable mechanism to secure MQTT systems.","PeriodicalId":347962,"journal":{"name":"Proceedings of the 15th ACM Workshop on Wireless Network Testbeds, Experimental evaluation & CHaracterization","volume":"22 8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131584260","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}
