Wireless sensor network is a key technology in the sensing layer of the Internet of Things. Data security in wireless sensor network is directly related to the authenticity and validity of data transmitted in the Internet of Things. Due to the large number and different types of nodes in wireless sensor networks, layered secret key sharing technology is increasingly used in wireless sensor networks. In a hierarchical secret sharing scheme, participants are divided into sections with different permissions for each team, but the same permissions for participants in the same team. In this article, we follow the approach of the hierarchical secret sharing scheme derived from the linear homogeneous recurrence relations. We design a hierarchical multi-secret sharing scheme for wireless sensor networks on the basis of the elliptic curve public key cryptosystem combined with the linear homogeneous recurrence relations. In the proposed scheme, we do not make sure that the participants are half-truthful. In addition, the participants’ shadows can be reused. Our scheme is computational security. Only one share from each member is required in our hierarchical multi-secret sharing scheme. It is more suitable for wireless sensor networks compared to the up-to-date schemes.
无线传感器网络是物联网传感层的一项关键技术。无线传感器网络中的数据安全直接关系到物联网传输数据的真实性和有效性。由于无线传感器网络中节点数量多、类型不同,分层密钥共享技术越来越多地应用于无线传感器网络。在分层秘密共享方案中,参与者被划分为多个部分,每个团队具有不同的权限,但同一团队中的参与者具有相同的权限。在本文中,我们遵循从线性齐次递推关系导出的分层秘密共享方案的方法。在椭圆曲线公钥密码体制的基础上,结合线性齐次递推关系,设计了一种用于无线传感器网络的分层多秘密共享方案。在拟议的方案中,我们没有确保参与者是半真实的。此外,参与者的阴影可以重复使用。我们的方案是计算安全。在我们的分层多秘密共享方案中,每个成员只需要一个共享。与最新的方案相比,它更适合于无线传感器网络。

In smart systems, attackers can use botnets to launch different cyber attack activities against the Internet of Things. The traditional methods of detecting botnets commonly used machine learning algorithms, and it is difficult to detect and control botnets in a network because of unbalanced traffic data. In this article, we present a novel and highly efficient botnet detection method based on an autoencoder neural network in cooperation with decision trees on a given network. The deep flow inspection method and statistical analysis are first applied as a feature selection technique to select relevant features, which are used to characterize the communication-related behavior between network nodes. Then, the autoencoder neural network for feature selection is used to improve the efficiency of model construction. Finally, Tomek-Recursion Borderline Synthetic Minority Oversampling Technique generates additional minority samples to achieve class balance, and an improved gradient boosting decision tree algorithm is used to train and establish an abnormal traffic detection model to improve the detection of unbalanced botnet data. The results of experiments on the ISCX-botnet traffic dataset show that the proposed method achieved better botnet detection performance with 99.10% recall, 99.20% accuracy, 99.1% F1 score, and 99.0% area under the curve.
在智能系统中,攻击者可以利用僵尸网络对物联网发起不同的网络攻击活动。传统的僵尸网络检测方法通常采用机器学习算法,由于网络中流量数据不均衡,难以对僵尸网络进行检测和控制。在本文中,我们提出了一种基于自编码器神经网络与给定网络上的决策树合作的新型高效僵尸网络检测方法。首先将深流检测方法和统计分析作为特征选择技术,选择相关特征,用于表征网络节点之间的通信相关行为。然后,利用自编码器神经网络进行特征选择,提高模型构建效率。最后,采用tomek -递归边界合成少数派过采样技术生成额外的少数派样本,实现类平衡,并采用改进的梯度增强决策树算法训练并建立异常流量检测模型,提高对不平衡僵尸网络数据的检测。在iscx -僵尸网络流量数据集上的实验结果表明,该方法具有99.10%的召回率、99.20%的准确率、99.1%的F1分数和99.0%的曲线下面积,取得了较好的僵尸网络检测性能。

Aiming at the problems of low data reconstruction accuracy in wireless sensor networks and users unable to receive accurate original signals, improvements are made on the basis of the stagewise orthogonal matching pursuit algorithm, combined with sparseness adaptation and the pre-selection strategy, which proposes a sparsity adaptive pre-selected stagewise orthogonal matching pursuit algorithm. In the framework of the stagewise orthogonal matching pursuit algorithm, the algorithm in this article uses a combination of a fixed-value strategy and a threshold strategy to screen the candidate atom sets in two rounds to improve the accuracy of atom selection, and then according to the sparsity adaptive principle, the sparse approximation and accurate signal reconstruction are realized by the variable step size method. The simulation results show that the algorithm proposed in this article is compared with the orthogonal matching pursuit algorithm, regularized orthogonal matching pursuit algorithm, and stagewise orthogonal matching pursuit algorithm. When the sparsity is 35 < K < 45, regardless of the size of the perception matrix and the length of the signal, M = 128, N = 256 or M = 128, N = 512 are improved, and the reconstruction time is when the sparsity is 10, the fastest time between 25 and 25, that is, less than 4.5 s. It can be seen that the sparsity adaptive pre-selected stagewise orthogonal matching pursuit algorithm has better adaptive characteristics to the sparsity of the signal, which is beneficial for users to receive more accurate original signals.
针对无线传感器网络数据重构精度低、用户无法接收到准确的原始信号等问题,在分阶段正交匹配追踪算法的基础上,结合稀疏自适应和预选策略进行改进,提出了一种稀疏自适应预选分阶段正交匹配追踪算法。在分阶段正交匹配追踪算法的框架下,本文的算法采用固定值策略和阈值策略相结合的方法,分两轮筛选候选原子集,以提高原子选择的准确性,然后根据稀疏性自适应原理,采用变步长方法实现了稀疏近似和精确的信号重构。仿真结果表明,本文提出的算法与正交匹配追踪算法、正则化正交匹配追踪方法和分段正交匹配追踪法进行了比较。稀疏度为35时 < K < 45,与感知矩阵的大小和信号的长度无关,M = 128,N = 256或M = 128,N = 512得到改善,并且重建时间是当稀疏度为10时,在25和25之间的最快时间,即小于4.5 可以看出,稀疏性自适应预选分段正交匹配寻踪算法对信号的稀疏性具有更好的自适应特性,有利于用户接收到更准确的原始信号。

Routing optimization in wireless sensor networks facilitates to reduce the overhead of the maintaining of wireless sensor networks and extend the lifetime of wireless sensor networks. Collection tree-based routing protocol, which does not require route discovery, has been widely used for low overheads of calculation and storage. However, with collection tree-based routing protocol, some nodes easily become the bottleneck points and quickly run out of the energy. To deal with this drawback, this article proposes a collection tree-oriented mesh routing strategy with cooperatively consuming the residual energy among the neighboring sensor nodes. The collection tree-oriented mesh routing is formulated into a linear programming problem with the purpose to maximize the network lifetime. By solving the optimization problem, the optimal mesh routing and data forwarding scheme is derived. Experimental simulations show that the proposed collection tree-oriented mesh routing optimization strategy can extend the network lifetime by more than 20%.
无线传感器网络中的路由优化有助于减少无线传感器网络的维护开销,延长无线传感器网络寿命。基于集合树的路由协议不需要路由发现,由于计算和存储开销小,已被广泛使用。然而,使用基于集合树的路由协议,一些节点很容易成为瓶颈点,并很快耗尽能量。针对这一缺点,本文提出了一种面向集合树的网格路由策略,该策略协同消耗相邻传感器节点之间的剩余能量。面向集合树的网格路由被公式化为线性规划问题,目的是最大化网络寿命。通过对优化问题的求解,得到了网格路由和数据转发的最优方案。实验仿真表明,所提出的面向集合树的网状路由优化策略可以将网络寿命延长20%以上。

Distributed sensor networks have emerged as part of the advancements in sensing and wireless technologies and currently support several applications, including continuous environmental monitoring, surveillance, tracking, and so on which are running in wireless sensor network environments, and large-scale wireless sensor network multimedia applications that require large amounts of data transmission to an access point. However, these applications are often hampered because sensor nodes are energy-constrained, low-powered, with limited operational lifetime and low processing and limited power-storage capabilities. Current research shows that sensors deployed for distributed sensor network applications are low-power and low-cost devices characterized with multifunctional abilities. This contributes to their quick battery drainage, if they are to operate for long time durations. Owing to the associated cost implications and mode of deployments of the sensor nodes, battery recharging/replacements have significant disadvantages. Energy harvesting and wireless power transfer have therefore become very critical for applications running for longer time durations. This survey focuses on presenting a comprehensive review of the current literature on several wireless power transfer and energy harvesting technologies and highlights their opportunities and challenges in distributed sensor networks. This review highlights updated studies which are specific to wireless power transfer and energy harvesting technologies, including their opportunities, potential applications, limitations and challenges, classifications and comparisons. The final section presents some practical considerations and real-time implementation of a radio frequency–based energy harvesting wireless power transfer technique using Powercast™ power harvesters, and performance analysis of the two radio frequency–based power harvesters is discussed. Experimental results show both short-range and long-range applications of the two radio frequency–based energy harvesters with high power transfer efficiency.
分布式传感器网络作为传感和无线技术进步的一部分而出现,目前支持多种应用,包括在无线传感器网络环境中运行的连续环境监测、监视、跟踪等,以及需要向接入点传输大量数据的大规模无线传感器网络多媒体应用。然而,这些应用往往受到阻碍,因为传感器节点能量受限、低功耗、有限的工作寿命、低处理和有限的电力存储能力。目前的研究表明,用于分布式传感器网络应用的传感器具有低功耗、低成本、多功能的特点。这有助于他们的电池快速排水,如果他们要长时间运行。由于相关的成本影响和传感器节点的部署模式,电池充电/更换具有显着的缺点。因此,能量收集和无线电力传输对于长时间运行的应用变得非常关键。本调查的重点是对几种无线能量传输和能量收集技术的当前文献进行全面回顾,并强调了它们在分布式传感器网络中的机遇和挑战。本文重点介绍了无线能量传输和能量收集技术的最新研究,包括它们的机遇、潜在应用、限制和挑战、分类和比较。最后一节介绍了使用Powercast™功率采集器的基于射频的能量收集无线电力传输技术的一些实际考虑和实时实现,并讨论了两种基于射频的功率采集器的性能分析。实验结果表明,这两种基于射频的能量采集器具有高功率传输效率的近距离和远程应用。

Sudden disaster events are usually unpredictable and uncontrollable, and how to achieve efficient and accurate disaster information dissemination is an important topic for society security. At present, social sensor networks which integrate human mobile sensors and traditional physical sensors are widely used in dealing with emergencies. Previous studies mainly focused on the impact of human mobility patterns on social sensor networks. In this article, based on the inherent autonomy property of human individuals, we propose a social sensor information dissemination model, which mainly focuses on the impact of the individual characteristics, social characteristics, and group information dissemination mode on social sensor networks. Specifically, the human sensor model is first constructed based on the inherent social and psychological attributes of human autonomy. Then, various information dissemination models such as one-to-one, one-to-many, and peer-to-peer are proposed by considering different transmission media and human interaction preferences. We simulate the environment of information dissemination in disaster events based on the NetLogo platform. Evaluation matrix is applied to test the performance of social sensor information dissemination model, such as event dissemination coverage, event delivery time, and event delivery rate. With the comparisons to epidemic model, social sensor information dissemination model shows excellent performance in improving the efficiency and accuracy of information transmission in disaster events.
突发灾害事件通常具有不可预测性和不可控性,如何实现灾害信息的高效准确传播是社会安全的重要课题。目前,将人类移动传感器和传统物理传感器相结合的社交传感器网络被广泛应用于突发事件的处理。先前的研究主要集中在人类流动模式对社交传感器网络的影响上。本文基于人类个体固有的自主性,提出了一种社会传感器信息传播模型,主要研究个体特征、社会特征和群体信息传播模式对社会传感器网络的影响。具体而言,人类传感器模型首先是基于人类自主性固有的社会和心理属性构建的。然后,通过考虑不同的传播媒介和人类互动偏好,提出了一对一、一对多和对等等各种信息传播模型。我们基于NetLogo平台模拟了灾害事件中的信息传播环境。评价矩阵用于测试社交传感器信息传播模型的性能,如事件传播覆盖率、事件传递时间和事件传递率。与流行病模型相比,社会传感器信息传播模型在提高灾害事件中信息传播的效率和准确性方面表现出优异的性能。

The idea of applying integer Reversible Colour Transform to increase compression ratios in lossless image compression is a well-established and widely used practice. Although various colour transformations have been introduced and investigated in the past two decades, the process of determining the best colour scheme in a reasonable time remains an open challenge. For instance, the overhead time (i.e. to determine a suitable colour transformation) of the traditional colour selector mechanism can take up to 50% of the actual compression time. To avoid such high overhead, usually, one pre-specified transformation is applied regardless of the nature of the image and/or correlation of the colour components. We propose a robust selection mechanism capable of reducing the overhead time to 20% of the actual compression time. It is postulated that implementing the proposed selection mechanism within the actual compression scheme such as JPEG-LS can further reduce the overhead time to 10%. In addition, the proposed scheme can also be extended to facilitate network-based compression–decompression mechanism over distributed systems.
在无损图像压缩中,利用整数可逆颜色变换提高压缩比的思想已经得到了广泛的应用。尽管在过去的二十年中已经引入和研究了各种颜色转换,但在合理的时间内确定最佳配色方案的过程仍然是一个开放的挑战。例如,传统颜色选择器机制的开销时间(即确定合适的颜色转换)可能占用实际压缩时间的50%。为了避免如此高的开销,通常,无论图像的性质和/或颜色成分的相关性如何,都应用一个预先指定的转换。我们提出了一种健壮的选择机制,能够将开销时间减少到实际压缩时间的20%。假设在实际的压缩方案(如JPEG-LS)中实现所提出的选择机制可以进一步将开销时间减少到10%。此外,该方案还可以扩展到分布式系统上基于网络的压缩-解压缩机制。

In addition, the proposed scheme can also be extended to facilitate network-based compression–decompression mechanism over distributed systems.","PeriodicalId":50327,"journal":{"name":"International Journal of Distributed Sensor Networks","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"65535113","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent years, the rapid development of Internet of Things smart hardware has increased the demand for intelligent control of devices, mainly in the smart home industry. The framework to solve the problem of equipment intelligent control is studied. The advantages and disadvantages of existing context modeling strategies are analyzed. According to the characteristics of household context activities, combined with the design principles of graph databases, a new context modeling method based on object and attribute graph is proposed, which is suitable for Internet of Things scenarios with limited resources. Rule control, mode control, and voice control approaches of smart home interaction are designed. An inference engine is used to map the data of context awareness to the Internet of Things control services that executed automatic control of the system, and a framework of smart control system based on context awareness of Internet of Things is proposed. Considering the behavior habits of users, the concept of user preference is introduced to provide more personalized services. Performance tests with simulated data show that the new context modeling method has a faster system response time than the ontology modeling control mode.

Due to the continuous expansion of congested urban areas, many new tunnels are inevitable to over-cross the existing subway lines and may even affect the operation of existing lines. It is vital to investigate the response of existing tunnel caused by over-crossing tunneling. In this study, a case history of closely spaced twin tunnels excavated above the existing tunnels in soft soil stratum was presented. The deformation of the existing tunnels induced by the excavation of the new tunnels was automatically monitored. In-situ monitoring results showed that the vertical displacement of the existing tunnels was mainly uplift and its development showed obvious phase characteristics. The increase rate of the vertical displacement in Phase I and II induced by the second over-crossing was smaller than that of the first over-crossing. A superposition method was employed to describe the uplift section characteristics of the existing tunnels. The influence ranges of tunnel excavation on the left and right lines of the existing tunnels were approximately 5.5D and 4.5D, respectively. The torsional deformation of the rail bed and the convergence of the existing tunnels are explored, and the reasons for the changes of the over-crossing sections are analyzed at the same time.
由于城市拥挤地区的不断扩大,许多新建隧道不可避免地要与现有地铁线路交叉,甚至可能影响现有地铁线路的运行。研究跨隧道施工对既有隧道的响应具有重要意义。本文介绍了软土地层中在既有隧道之上开挖密距双隧道的实例。对新隧道开挖引起的既有隧道变形进行了自动监测。现场监测结果表明,既有隧道竖向位移以上拔为主,其发展具有明显的阶段性特征。第2次过桥引起的第1期和第2期垂直位移增幅小于第1次过桥。采用叠加法对既有隧道的上拔断面特征进行了描述。隧道开挖对既有隧道左右线的影响范围分别约为5.5D和4.5D。探讨了轨道床的扭转变形和既有隧道的收敛,同时分析了跨断面变化的原因。
