    Potential and methods of wireless communications for Internet of things based on UAV by Qingheng SONG, Fuchun ZHENG

    Published 2019-03-01
    “…In the absence of terrestrial infrastructure for Internet of things (IoT),an effective low-cost wireless connection can be provided by an unmanned aerial vehicle (UAV) based wireless communication platform.Compared with the terrestrial IoT communication platform,the low-altitude UAV wireless communication system enjoys the advantage of rapid deployment,low cost,on-demand deployment,flexible configuration and better communication channel quality due to short-range line-of-sight links.On the other hand,several new challenges must be overcome due to the high mobility and energy consumption limitations of UAV.An overview of UAV enabled IoT wireless communication was provided,including the air-to-ground channel model,the power consumption model,as well as the applications in UAV based data dissemination/collection and relay,with particular reference to the new opportunities and solutions in these application areas.…”

    Blockchain-based ARP defense scheme by Fanming LIU, Wei SHI

    Published 2018-09-01
    “…In order to improve the difficulty of maintaining the static binding method when defending against ARP attacks,a defense method was designed with the features of low cost of defense and easy maintenance by using the idea of a blockchain technology.The blockchain structure had been improved,and the transaction index table structure had been designed to identify attacks and update data in a timely manner to prevent subsequent attacks.The content of the transaction index table was updated after the IP address was changed normally to ensure the correctness of the query.Analysis and experiments show that the blockchain-based defense method has the following merits:high security,guaranteeing the data is not tampered with,low cost of maintenance,and effective prevention against ARP spoofing attacks.…”
