    Data-driven data transmission of the Internet of things based on sensing spectrum by Xuanheng LI, Yi SUN, Jie WANG, Haixia ZHANG

    Published 2019-06-01
    “…Facing the problem of spectrum shortage caused by the mass data,in order to share as a solution,how operators use the sensing spectrum reasonably to transmit data was studied.Considering the limitation of Internet of things(IoT) devices,the ultra-dense cognitive heterogeneous network architecture was designed,based on traffic demand and perception cost,an optimal access control and perception decision method was designed to maximize network utility.Considering the uncertainty of the perceived spectrum,the optimal programming scheme was modeled as a mixed integer stochastic optimization problem,and a data-driven probabilistic solution method based on statistical characteristics was proposed.In the case of unknown probability distribution of available bandwidth,data transmission requirements meeting various service requests were counted.…”

    ALVIC versus the Internet: Redesigning a Networked Virtual Environment Architecture by Peter Quax, Jeroen Dierckx, Bart Cornelissen, Wim Lamotte

    Published 2008-01-01
    “…The Architecture for Large-Scale Virtual Interactive Communities (ALVICs) was originally developed to serve as a generic framework to deploy networked virtual environment applications on the Internet. While it has been shown to effectively scale to the numbers originally put forward, our findings have shown that, on a real-life network, such as the Internet, several drawbacks will not be overcome in the near future. …”

    Data comparable encryption scheme based on cloud computing in Internet of things by Qian MENG, Jianfeng MA, Kefei CHEN, Yinbin MIAO, Tengfei YANG

    Published 2018-04-01
    “…The previously proposed short comparable encryption (SCE) scheme can infer the plaintext relationship by comparing the ciphertexts relationship as well as ensuring data security in Internet of things.Unfortunately,it will incur high storage and computational burden during the process of comparing ciphertexts and generating tokens.To this end,an efficient short comparable encryption scheme called SCESW was proposed,which was utilizing the sliding window method with the same size window.Formal security analysis shows that the scheme can guarantee weak indistinguishability in standard model as well as data security and integrity.The experimental results demonstrate that the storage of the SCESW scheme is <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML"> <mfrac> <mn>1</mn> <mi>t</mi> </mfrac> <mo stretchy="false">(</mo><mi>t</mi><mi>></mi><mn>1</mn><mo stretchy="false">)</mo></math></inline-formula> times shorter than that of the SCE scheme and the efficiency of the SCESW scheme is superior to that of the SCE scheme.…”
