Specific primary user sensing for wireless security in IEEE 802.22 network

作者： Zhenxing Luo Caiyi Lou Shichuan Chen Shilian Zheng Shaowei Li Science and Technology on Communication Information Security Control Laboratory Jiaxing China

Cognitive Radio (CR) is considered as an effective technology for alleviating the spectrum shortage problem by enabling secondary users to utilize vacant spectrum allocated to a primary user (PU). IEEE 802.22 which is the first standard based on CR is developed to increase the efficiency of TV bands. However the physical layer security of IEEE 802.22 has been studied rarely. In this paper, we propose a scheme to sense the specific primary user for dealing with Primary User Emulation (PUE) Attack which is a possible threat to wireless security. According to ATSC digital TV which is one of the important PUs, we estimate the accuracies of pilot and symbol rate as RF fingerprint (RFF), and Support Vector Data Description (SVDD) is introduced to sense the fine differences of RFF to distinguish PUE attacker from PU. The simulation results show that the proposed scheme is feasible to verify the PUE attacker at a relative high SNR level.

Aiming at the modulation recognition problem of mixed signal set {BPSK, QPSK, BPSK-FM, QPSK-FM} with unknown parameters, this paper proposes a modulation recognition algorithm based on two-fold PLL (phase locked loop) and goodness of fit test. The PLL is used to extract the features of the composite modulation signal, and the goodness of fit test is used to measure the distance of the phase cumulative distribution of the demodulation information. Theoretical analysis and simulation results show that the performance of the recognition method based on two-fold PLL and goodness of fit test is better than the widely used modulation recognition method based on constellation. ©2021 IEEE.

International Conference on communication technology (ICCT)

作者： Jianjun Jiang Shilian Zheng Science and Technology on Communication Information Security Control Laboratory Jiaxing China

In cognitive radio networks, when a primary user reoccupies the channel, cognitive radios (CRs) need to vacate the channel and reestablish a link on some other channel to avoid interference to primary users, resulting in spectrum handoff. A joint spectrum handoff delay and link maintenance optimization problem for spectrum handoff is formulated in this paper. A binary shuffled frog leaping algorithm (SFLA) based algorithm is proposed to solve this problem. Simulations show that the proposed algorithm performs far better than random target channel visiting scheme. It can obtain solutions with low handoff delay and low probability of handoff failure which are very close to the optimal solutions.

International Symposium on communications and information Technologies (ISCIT)

作者： Shilian Zheng Xiaoniu Yang Science and Technology on Communication Information Security Control Laboratory Jiaxing China

Wideband spectrum sensing is a fundamental problem in cognitive radio networks. In this paper, a wideband spectrum sensing procedure which consists of four steps, i.e., coarse support recovery, fine binary detection, band edges detection and clustering, for modulated wideband converter (MWC) based cognitive radio system at sub-Nyquist rate is proposed. Simulations show that with a sub-Nyquist sampling rate, the proposed spectrum sensing procedure can locate spectrum holes correctly.

Since the advancement of mobile communication technology, traditional industries are gradually transforming and upgrading, which leads to problems such as insufficient computing resources and excessive energy consumption of Internet of Things (IoT) devices. To address this issue, a resource allocation algorithm for the mobile edge computing-assisted industrial IoT (IIoT) is proposed. First, a mobile edge computing-assisted IIoT network model was constructed. Using the collaboration between IoT devices, mobile edge computing (MEC) servers, and cloud servers, the issue of minimizing all IIoT devices energy cost was proposed. Subsequently, in order to address the optimization issue, obtain its optimal solution, the alternating direction method of multipliers (ADMM) algorithm is introduced. Finally, the ADMM algorithm's convergence was verified through an experimental simulation. In contrast to baseline algorithm 1 and algorithm 2, the ADMM algorithm can significantly diminish energy cost, proving the effectiveness of the proposed scheme. © 2023 IEEE.

International Symposium on communications and information Technologies (ISCIT)

作者： Shilian Zheng Xiaoniu Yang Caiyi Lou Science and Technology on Communication Information Security Control Laboratory Jiaxing China

Spectrum sensing is one of the fundamental problems for cognitive radio. In cognitive radio networks, cognitive radios can cooperatively sense the spectrum to detect the presence of primary users with higher sensitivity. This paper proposes distributed consensus algorithms for decision fusion based cooperative spectrum sensing. Both theoretical analysis and simulations are performed to show the convergence property of the algorithms. Results show that the proposed algorithms can realize central OR, AND, and M-out-of-n decision fusion rules by locally exchanging information among each radio and its adjacent neighbors in a distributed way.

As the space environment of information transmission becomes more and more complex, the accuracy of communication becomes a new challenge. In order to study the anti-jamming performance of code shift keying (CSK), this paper mainly simulates the performance of CSK and binary phase shift keying (BPSK) under 5 signal interferences, and discusses it according to the bit error rates (BER) obtained by simulation. In the face of different forms of signal interference, CSK has better anti-jamming performance than BPSK. Under various forms of signal interference, CSK has the strongest anti-interference ability to multi-tone interference, and its anti-interference ability to pulse interference, 50% narrowband interference, single-tone interference and channel noise decreases successively. © 2022 IEEE.

Wireless communication network has such features as limited bandwidth, changeful channel and dynamic topology, etc. Ad hoc network has lots of difficulties in accessing control, bandwidth distribution, resource assign and congestion control. Therefore, a wireless resource distributing algorithm based on communication transmission performance factors is proposed in the paper. The algorithm makes quantitative and qualitative analysis for influencing factors of transmission performance, as a result, node resource distribution "relative unfairness" is introduced to realize resource re-distribution while network resource is changing. At the same time, in order to ensure fairness of data transmission and timeliness of network packets, transmitting priority levels for each data packets are established based on latency time and its original priority level in the node. The simulation results show that the algorithm can ensure fairness and timeliness of network transmission, as well as improve ad hoc network resource integrated utilization efficiency. © 2012 IEEE.

A method of time difference of arrival (TDOA) location for shortwave signal source by four receiving stations is introduced. The precision of time difference and the Geometric Dilution of Precision (GDOP) of TDOA location are analyzed and simulated. The results show that TDOA estimation performance is positively correlated with signal bandwidth, signal cumulative time and signal-to-noise ratio (SNR), while TDOA location precision is positively correlated with TDOA estimation precision and distance between the receiving stations. At the same time, the simulation analysis of station arrangement among multiple stations is carried out, and the results show that Y-shaped station mode gets the best location effect. © 2021 IEEE.
