Aiming at problems such as insufficient communication coverage, high power consumption and complex deployment, a low- power wide-area monitoring network architecture based on LoRa technology is proposed in this paper. The network adopts the dual-star hybrid topology, combines the dynamic spread factor allocation and time division multiplexing mechanism, and realizes the balance between low power consumption and long distance communication by optimizing the configuration of LoRa parameters (bandwidth, spread factor, coding rate).Regarding hardware design, the STM32 series microcontroller and SX1268 RF module are used to build terminal nodes, which support multi-sensor access and power partition management. At the software level, an adaptive anti-collision algorithm is proposed, which combines signal enhancement and collision decoding technology to improve network reliability.

These days, Cloud Computing is widely used in different applications such as Civis Analytics and AWS (Amazon Web Services). Through the virtualization of hardware and software, Cloud Computing delivers various services to users over the Internet. The main challenge of providing satisfactory quality of service to the users is workflow scheduling, an NP-hard problem that has been a topic of much research. In this paper, BRADO, a recently-developed swarm intelligence algorithm, has been introduced for allocating and scheduling tasks to appropriate resources. This proposed algorithm aims to minimize the total execution time of the whole workflow, known as makespan. The performance of this proposed algorithm has been evaluated using the CloudSim Plus toolkit. Moreover, the results have been compared with some well-known algorithms, including PSO and SA. Our findings show the superiority of the BRADO algorithm in allocating and scheduling tasks. © 2022 IEEE.

software vulnerabilities are bugs in a program that an attacker can exploit to make the program deviate from its specification. An attacker exploits a vulnerability by crafting input that causes the program to behave incorrectly. Such an input is called an exploit. This article deals with diagnosing exploits, i.e., given an exploit, the task is to return the vulnerability that allowed it. We show that existing software diagnosis algorithms are ill-suited for this problem, and introduce two novel techniques for adapting them to this problem. This includes manipulating an automated testing tool to generate additional inputs that are similar to the given exploit, and tracing below the desired granularity level to improve diagnostic accuracy. Experimental evaluation on real exploits from four open-source projects shows that our algorithm significantly reduces diagnostic efforts.

Cyber-attacks are evolving at a disturbing rate. Data breaches, ransomware attacks, crypto-jacking, malware and phishing attacks are now rampant. In this era of cyber warfare, the software industry is also growing with an increasing number of software being used in all domains of life. This evolution has added to the problems of software vendors and users where they have to prevent a wide range of attacks. Existing watermark detection solutions have a low detection rate in the software. In order to address this issue, this paper proposes a novel blind Zero code based Watermark detection approach named KeySplitWatermark, for the protection of software against cyber-attacks. The algorithm adds watermark logically into the code utilizing the inherent properties of code and gives a robust solution. The embedding algorithm uses keywords to make segments of the code to produce a key-dependent on the watermark. The extraction algorithms use this key to remove watermark and detect tampering. When tampering increases to a certain user-defined threshold, the original software code is restored making it resilient against attacks. KeySplitWatermark is evaluated on tampering attacks on three unique samples with two distinct watermarks. The outcomes show that the proposed approach reports promising results against cyber-attacks that are powerful and viable. We compared the performance of our proposal with state-of-the-art works using two different software codes. Our results depict that KeySplitWatermark correctly detects watermarks, resulting in up to 15.95 and 17.43 percent reduction in execution time on given code samples with no increase in program size and independent of watermark size.

The availability of inexpensive software defined radios (SDR) has enabled the deployment of cognitive radio (CR) features in large-scale networks such as internet-of-things (IoT). However, such radio receivers are limited by their non-ideal characteristics like coloured noise, IQ imbalance, phase noise etc. Performance of existing spectrum sensing algorithm degrade in coloured noise due to swelling effect of received signal covariance matrix. To overcome this limitation, we propose a novel spectrum sensing technique based on extreme learning machine (ELM) which uses eigenvalue and log determinant (LogDet) of covariance matrix features. Experimental results show the effectiveness of the proposed technique over existing algorithms in literature. © 2022 IEEE.

The security of smart devices is facing great challenges. This article presents a new hybrid cipher framework suitable for such devices. Using software/hardware (SW/HW) co-design method, an efficient encryption/decryption and digital signature scheme based on SM2, SM3, and SM4 algorithms is implemented. First, the framework is partitioned into software and hardware parts based on the analysis result of a pure software solution and the hardware overhead under the conditions of design constraints. Second, the flow of the whole scheme and embedded algorithms are realized by SW/HW co-design. Finally, an improved implementation of SM2/3/4 algorithms is proposed to achieve higher efficiency. In this implementation, some SW/HW modules are parallelized to reduce the running time and enhance the performance. The proposed design is safe and can resist simple power analysis (SPA) attacks. Especially, the AHB bus interface IP and software scheduling approach are adopted in data transfer and manipulation. The design is taped-out on a silicon chip with SMIC 110-nm technology process. The chip uses about 199K logic gates and 1-mm(2) areas. The operating frequency of the design is 36 MHz and the chip consumes 23-mW power. The comparison with similar previous works shows our proposed design is more efficient with speed increasing of more than 10%.

Development of dedicated software for analyzing the currents under fault conditions in a network has quite important prospects. A computer program simulating real emergency conditions of network operation is able to yield much more accurate data in comparison with the analysis procedures suggested in regulatory documents. This is especially the case in simulating arc faults, because models take into account the arc breakdown nonlinearities. In addition, a study of arc characteristics will help develop and further sophisticate special equipment for protection against the occurrence of arch breakdowns in a network. In this article, we present our developments of an arc simulation model in the Matlab/Simulink software package and suggest an algorithm of a program for numerically analyzing the currents occurring under fault conditions in a low voltage distribution network. © 2022 IEEE.

Swarm robotics and coordinated navigation have many important applications in smart cities. For example, on the street, autonomous cars may coordinate with each other to optimize the routes and city traffic;in a building, multiple robots may allow the coordinated search of trapped people in the building after a fire or natural hazard. It is important to study how to design and optimize the coordinated search strategy in those complicated smart city environments. This paper introduces RoboMaze, a simulator for swarm robotics and coordinated navigation study, where the robots may communicate with each other and optimize their paths with the goal of completing the search in a minimum amount of time. RoboMaze has been implemented and demonstrated in multiple software and hardware platforms. It not only greatly facilitates the development and test of new algorithms, but also serves as a wonderful education and outreach tool for smart city awareness. © 2021 IEEE.

Compared with fossil energy with limited reserves and high pollution, clean and reliable distributed power supply has increasingly become an excellent substitute for traditional fossil energy. The gradual increase of the grid-connected scale of distributed power generation in the power grid system has brought great challenges to the existing distribution network protection, and the traditional three-stage protection is difficult to meet the needs of the development of the future power grid system. In this paper, firstly, the output characteristics of distributed power supply and the fault characteristics of distribution network with distributed power supply are analyzed, the fault information of each location of distribution network is obtained by communication, the correlation matrix between nodes and branches and nodes is constructed, and the matrix optimal path is obtained by using Dijkstra algorithm. Based on this, the current protection optimization scheme of distribution network based on multi-point information is formed. Finally, an example is simulated by PSCAD/EMTDC and MATLAB simulation software, and the simulation results verify the reliability of the scheme. © 2022 IEEE.
