Hence physical-layer identification methods are proposed to validate the authenticity of passive tags. However no existing physical-layer authentication method of RFID tags that can defend against the signal replay attack. This paper presents Hu-Fu, a new direction and the first solution of physical layer authentication that is resilient to the signal replay attack, based on the fact of inductive coupling of two adjacent tags. We present the theoretical model and system workflow. Experiments based on our implementation using commodity devices show that Hu-Fu is effective for physical-layer authentication.","PeriodicalId":328007,"journal":{"name":"HotWireless '17","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128532037","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 has been considered to employ wireless backhaul for moving cell, the problem of which is its limited and unstable bandwidth. To realize high bandwidth with wireless backhaul, a large number of base stations (BSs) are required along the railway. Therefore, this paper proposes the concept of optically backhauled moving network (OBMN) for local trains to efficiently provide backhaul links for local trains. In the OBMN, an autonomous BS (ABS) is set on the top of a train, and is connected to a gateway via optical backhaul. To follow the movement of the train, the length of optical fiber is adequately adjusted with a high-speed reel, which is located along the railway and spins to reel up and send out the fiber. When the train arrives at a transfer point, another ABS is set on the train and the demand is handovered to the newly set ABS. The number of required BSs and deployment cost will be drastically reduced with the proposed OBMN compared with the existing static deployment.","PeriodicalId":328007,"journal":{"name":"HotWireless '17","volume":"168 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121399344","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}

Due to the non-deterministic nature of event arrivals, multi-hop dissemination using state-of-the-art radio duty-cycled protocols leads to a trade-off between latency and energy efficiency. In order to circumvent this system design constraint, we propose BLITZ, a network architecture that leverages interference-based flooding to rapidly wake-up the multi-hop network and disseminate the event on-demand. We show that by embracing network flooding in combination with simultaneous transmissions, we can realize low latency event-triggered multi-hop communication without having to sacrifice energy efficiency. We introduce an analytical model to quantify the limits of our approach, present a prototype implementation using a multi-radio wireless sensor platform, and experimentally evaluate BLITZ in a laboratory setting and in an indoor testbed.","PeriodicalId":328007,"journal":{"name":"HotWireless '17","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115480224","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, wireless many-to-many broadcast has thus far only been studied theoretically or in simulation, and practical solutions hardly meet the requirements of emerging applications, especially in terms of latency. This paper presents Mixer, a communication primitive that provides fast and reliable many-to-many broadcast in dynamic wireless multi-hop networks. Mixer integrates random linear network coding with synchronous transmissions to simultaneously disseminate all messages in the network. To deliver the performance gains our approach enables, we design Mixer's protocol logic in response to the physical-layer characteristics and the theory of network coding. First results from testbed experiments demonstrate that, compared with the state of the art, Mixer is up to 65% faster and reduces radio-on time by up to 50%, while providing a message delivery rate above 99.9%.","PeriodicalId":328007,"journal":{"name":"HotWireless '17","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116656111","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 the open access network model, the municipality/community can act as the network operator and a multitude of services can be provided to the end users over the deployed infrastructure. In this age of wireless networks and mobile users, WiFi must also be an integral part of the open access network. We discuss the need for designing WiFi from the point of view of open access networks. We identify the aspects of WiFi that need to be modified and the challenges that arise due to these modifications. We address these challenges by presenting a simple, yet novel design for enabling WiFi in open access networks using SDN and access point virtualization. Ours is the first attempt towards integrating open access networks and WiFi. We implement a preliminary prototype of our design in the Emulab test bed and successfully verify its operation.","PeriodicalId":328007,"journal":{"name":"HotWireless '17","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121158108","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 past few years have seen signficiant progress with systems demonstrating the ability to synthesise transmissions that are compatible with WiFi, ZigBee or BLE at μWs of power consumption. However, these systems achieve a maximum communication range of tens of meters which severely limits the possible applications. On the other hand, our recent system LoRea demonstrates that backscatter communication can achieve a significantly longer range reaching up to a few kms when the tag is co-located with the carrier source. In our vision, such a large range could be a key enabler to develop wide-area networks of battery-free sensors. In this paper, we build on our system LoRea and identify issues of improving the reliability of weak backscatter links, increasing the range and supporting the operation of multiple tags as the key challenge to our vision, and present our preliminary efforts to address them.","PeriodicalId":328007,"journal":{"name":"HotWireless '17","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115201420","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}

Numerous cellular applications, including video streaming and VoIP, embed logic that attempts to estimate achievable throughput and adapt their behaviour accordingly. We believe that providing applications with reliable predictions several seconds into the future would enable profoundly better adaptation decisions and dramatically benefit demanding applications like mobile virtual and augmented reality. The question we pose and seek to address is whether such reliable predictions are possible. We conduct a preliminary study of throughput prediction in a cellular environment using statistical machine learning techniques. An accurate prediction can be very challenging in large scale cellular environments because they are characterized by highly fluctuating channel conditions. Using simulations and real-world experiments, we study how prediction error varies as a function of prediction horizon, and granularity of available data. In particular, our simulation experiments show that the prediction error for mobile devices can be reduced significantly by combining measurements from the network with measurements from the end device. Our results indicate that it is possible to accurately predict achievable throughput up to 8 sec in the future where 50th percentile of all errors are less than 15% for mobile and 2% for static devices.","PeriodicalId":328007,"journal":{"name":"HotWireless '17","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130628614","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 enables very long range (up to 15 km) wireless communications with very low-power consumption. Many applications are being enabled by LoRa, such as water flow monitoring, animal tracking, smart parking, among many others. Although LoRa has attracted significant attentions from both industry and academia, its current cost and energy consumption are bringing inconveniences for the academia to exploit and improve LoRa's performance, e.g., when massive deployment of LoRa nodes are required in order to study the scalability performance of LoRa networks. In this paper, we design and implement uLoRa, an ultra low-power, low cost, and open-source platform for LoRa networks. uLoRa is built around an ultra low-power ARM processor. Each uLoRa node only costs ≈10 euros. To reduce the energy consumption of uLoRa, we optimize its design and implementation in both the hardware and software. We evaluate the performance of uLoRa with experiments, in terms of energy consumption and communication coverage. Compared to state-of-the-art LoRa platform, uLoRa can reduce the cost by two thirds and can double the battery life of the nodes. We also demonstrate the flexibility of uLoRa through the application of moisture monitoring.","PeriodicalId":328007,"journal":{"name":"HotWireless '17","volume":"180 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115831842","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}
