Game theory is applied to studying the P2P resource allocation technologies further in this paper. The mechanism of P2P resource pricing, which shows the relation of supply and demand, was presented based on bidding. Subsequently, we designed the utility function of end system and proved the existence and uniqueness of Nash Equilibrium in P2P resource allocation game. At last, we present a P2P resource allocation algorithm (PRANG) based on the resource allocation game model. The results of experiment and simulation show that PRANG algorithm can provide references for the quantity of resource that users demand and regularize the users' bids. Consequently, the allocation of the whole P2P resource tends to be more reasonable.

recently, intelligent home instruments developed fast and have been deployed widely while a crucial problem of how dealing the left devices and properties come up to the top of the water. This paper presents a remote gas meter reading system based on multimedia Zigbee networks and digital image recognition technologies to alleviate difficulties existing in traditional gas meter reading work while keeping existing gas meters unchanged. In the system, sensor nodes take picture of gas meter by a CMOS camera and send it to the sink node over multi-Zigbee-hop in a residential quarter. Then the gas providing company can access gas meter pictures through the Internet and recognize the data automatically by computer vision technology. Making up the gap between the high bandwidth consuming, high reliable requiring picture transport and the bandwidth constrained, error-prone Zigbee networks, this paper also proposes an opportunistic routing with network coding method to improve end-to-end throughput of the whole network. © 2012 IEEE.

in high-voltage substations, poor contacts at the junctions of contacts can generate heat leading to high temperature, arc and fire disaster in serious condition. In this paper, we present a remote temperature monitor system to monitor and alarm when temperature of the contacts increases. The system measures temperature by sensor node based on low power consuming temperature sensor and Zigbee communication because power consuming becomes a critical fact constrained by long term running and inconvenient maintenance of high-voltage substations. In the system, sensor nodes are deployed on the contacts to be measured, cluster headers in charge of collecting data from sensor nodes are deployed on each distributor and cluster headers are connected with mast monitor computer via RS485 network. This paper presents design, implementation and test of sensor nodes, cluster headers and the master monitor software. © 2012 IEEE.

Treachery is one of the restrictions to the development of electronic commerce. To prevent the treachery from the participants in electronic commerce, in this paper a secure electronic payment scheme is proposed and its security is analyzed. This scheme can prevent the treachery only with the aid of an un-trusted third party. It is very simple and it also improves the security and provides the non-repudiation, accountability, fairness and privacy.

A new security test for the substitution boxes （S-boxes） high-order bit independence criterion （HOBIC） test, is presented. Different from the previous security tests for S-boxes, the HOBIC test can be used to measure the strength of an S-box against attacks that keep some of its input bits constant. Test results over the S-boxes of Data Encryption Standard （DES） and Advanced Encryption Standard （AES） are given and some possible applications of the HOBIC test are analyzed. Meanwhile, the source code for a basic version of the HOBIC test is also provided, the implement process of which shows that it is very fast and efficient for practical applications .

Optoelectronics Letters 2019年第6期15卷 476-480页

A miniature fiber-coupler-based microfluidic system is proposed for trapping of DNA biomolecules. The loop-shaped fiber-coupler is fabricated by using flame tapering technique and integrated in a microfluidic channel. Probe-DNA immobilized on the fiber-coupler surface enables specific recognition of target DNA sequences and effectively facilitates the trapping of target DNA molecules. The binding characteristics of biomolecules on the fiber-coupler surface have been theoretically analyzed and experimentally demonstrated. Experimental results indicate that the spectral response of the loop-shaped fiber coupler immobilized with probe DNA exhibits a red-shift with the trapping of the DNA biomolecules. The proposed microfluidic system possesses such desirable merits as simple structure, label-free method and high integration, which make it a promising candidate for applications in molecular biology and related bioengineering areas.

A resilient trust management scheme for defending against reputation time-varying attacks based on BETA distribution

引用

Science China(information Sciences) 2017年第4期60卷 60-70页

作者： Weidong FANG Wuxiong ZHANG Yang YANG Yang LIU Wei CHEN Key Laboratory of Wireless Sensor Network & Communication Shanghai Institute of Microsystem and Information Technology Chinese Academy of Sciences Shanghai Research Center for Wireless Communication School of Computer Science and Technology China University of Mining and Technology

Compared with the encryption and the authentication which can prevent the external attacks,the trust management schemes are the better approaches for defending against the internal attacks in wireless sensor network(WSN). The reputation time-varying(RTV) attacks are internal attacks. In the reputation timevarying attacks, the reputation value of nodes is manipulated to adjust dynamically by the compromised nodes or malicious attackers. Hence, these attacks have greater covert and invasive. In this paper, we propose a Timewindow-based Resilient Trust Management Scheme(TRTMS) to defend against the reputation time-varying attacks in wireless sensor network. In this scheme, based on BETA distribution, the behaviors of compromised nodes are analyzed for a period of time, and then the difference judgment and the trend analysis are utilized to identify the abnormality of nodes’ reputation value, meanwhile, the control factor Fc and the time window are introduced to verify and remove the compromised modes from the suspected malicious nodes, which refer to those nodes’ reputation value changes are caused by the wireless channel changes. The result of simulation shows that our proposed scheme can defend reputation time-varying attacks effectively and it is convenient to implement.

Securing STAR-FC-RIS empowered integrated sensing and multiuser communications against target eavesdropping

引用

Science China(information Sciences) 2024年第11期67卷 335-346页

作者： Shuying LIN Yulong ZOU Fu XIAO Bin LI School of Telecommunications and Information Engineering Nanjing University of Posts and Telecommunications School of Computer Science Nanjing University of Posts and Telecommunications Key Laboratory of Broadband Wireless Communication and Sensor Network Technology Nanjing University of Posts and Telecommunications

This paper investigates a simultaneous-transmitting-and-reflecting fully-connected reconfigurable intelligent surface(STAR-FC-RIS) empowered integrated sensing and multiuser communications(ISAMC) network, where a dual-functional radar-communication base station detects a malicious radar target nearby and communicates with multiple legitimate users on the other side of the STAR-RIS. We utilize an integrated architecture that combines the fully-connected(FC)-RIS, an emerging type of beyond-diagonal(BD)-RIS, with the time-switching(TS)-STAR-RIS to enhance both the sensing and communications at the cost of possible target intercepting and propose the simultaneous-transmitting-and-reflecting fully-connected RIS(STAR-FCR) schemes to strike a balance between sensing and communications performance. Thereafter, observing the security-reliability performance tradeoff of the downlink ISAMC, we conduct closed-form analyses to compare COPs of round-robin scheduling(RS) and multiuser scheduling(MS) with the aid of a TS-based STAR-FC-RIS. Furthermore, we derive closed-form expressions of the sensing outage probability, communications outage probability(COP), and communications intercept probability, where an average of the three probabilities is exploited to obtain an optimized time allocation(OTA) of the *** results verify that the STAR-FCR-MS scheme outperforms the STAR-FCR-RS scheme in terms of sensing reliability and communications security. Moreover, an OTA remarkably enhances the overall performance of the STAR-FCR schemes of ISAMC systems.
