The authentication error in Two-Hop wireless networks is considered without knowledge of eavesdropper channels and location. This paper presents an eavesdropper model with authentication error and two eavesdropping ways. In the model, the authentication error is expressed a pair(p_1, p_2). Based on the authentication error, a cooperative transmission protocol against impersonation attack is presented. Then, the number of eavesdroppers can be tolerated is analyzed while the desired secrecy is achieved with high probability in the limit of a large number of relay nodes. Final, we draw two conclusions for authentication error: 1) the impersonate nodes are chosen as relay is the dominant factor of the transmitted message leakage, and the impersonation attack does seriously decrease the number of eavesdroppers can be tolerated. 2) The Error authentication to legitimate nodes is almost no effect on the number of eavesdroppers can be tolerated.

Frequency shift keying (FSK) modulation function in MATLAB without filter function, leading to poor adjacent channel suppression, which causes aliasing after a non-linear device easily. Based on FSK modulation signal generation principle, designing a better adjacent channel suppression function in this paper, which verified by demodulating through Agilent's vector signal analyzer (89600S), this function gets achieved more satisfactory results in the application of semi physical simulation.

Anonymous aggregator election protocol for wireless sensor networks

Tongxin Xuebao/Journal on Communications 2015年第2期36卷

An anonymous cluster head election protocol in clustered wireless sensor networks was proposed. The protocol detailed the decision rules and mode of cluster construction while an anonymous veto protocol based on bilinear pairings was adopted to verify election results, ensuring the successful election of cluster heads. A corresponding anonymous data aggregation scheme was designed, through which data aggregation can be accomplished without revealing the identities of aggregators. Extensive analysis and simulation results show that the proposed protocol achieves anonymity, energy efficiency and security of cluster heads election simultaneously and can resist eavesdropping attacks, node compromise attacks and collusion attacks effectively. ©, 2015, Tongxin Xuebao/Journal on Communications.

Resource allocation in ofdma-based cognitive radio networks via cooperation with primary users

Journal of Communications 2015年第5期10卷 294-300页

This paper considers an OFDMA-based cooperative cognitive radio network where the secondary users (SUs) act as the relay of the primary users (PUs) while guaranteeing the quality of service (QoS) of the PUs. In return, the SUs access the spectrum licensed to PUs in both time and frequency without impacting the communication of the PUs. A joint resource allocation problem is formulated to maximize the data rate of the SUs. It is proven that the optimization problem can be decomposed into two coupled subproblems which are power allocation and relay selection. The power allocation adopts the water-filling algorithm using the Lagrangian method, and the optimal relay selection is solved by Hungarian method. Simulation results show that the proposed algorithm can bring revenue to both the PUs and SUs. © 2015 Journal of Communications.

10G Ethernet technology has been widely used in modern high speed communication system. As a result, program design for high-speed data capture on 10G Ethernet, as the first and important step in network monitor and analysis system, has become a challenging task. This paper proposed a high-speed data capture method based on WinCap and shared memory pool technology and has features of high speed, low packet loss rate, high efficiency and good portability. The system test and data analysis proved that the proposed method in this paper can effectively capture the data at speed of 6Gbps and stably keep the packet loss rate under 0.03%. © (2014) Trans Tech Publications, Switzerland.

The routing protocol is the core of the Ad Hoc network protocols, which largely determines the performance and features of an Ad Hoc network. Aiming at the characteristics of the Mobile Radio Ad Hoc network, this paper is to design a low-rate mobile Ad Hoc network routing protocols WLRP (Wireless Low-Rate Ad Hoc security Routing Protocol), using the trust evaluation mechanism between neighbour nodes which can effectively prevent attacks from inside the network, to greatly enhance the Ad Hoc Network security. Simulation results show that in low-Rate link environment, the WLRP protocol performs better than AODV.

Role identification for network user plays a very important role in function and behaviour network analysis against criminal groups. Therefore, a network key role identification algorithm based on behaviour accumulation is proposed in the paper. Firstly, behaviour attribution of node (user) in network instance is extracted in the algorithm, description and abstraction of user behaviour by vector mode is performed, simultaneously, K mean algorithm is adopted to make clustering analysis for user behaviour;on the basis of conditions described as above, Hybrid Ant-Colony Algorithm (HBACA) is modified to search relationships between variety of grouping sets in the network instance, and identify each user role in the performing process of network instance. Simulation result shows that the algorithm can extract internal relations of communication behaviours between each network member, in order to obtain key role in a specific network instance.

The aerosol fire extinguishing agent is a complex pyrotechnic composition, and the extinguishing efficiency need a series of experiments to identify. A method is put forward out based on combining back-propagation neural network and genetic algorithm (BP-GA) in this paper, and then the performance of aerosol fire extinguishing agent can be predicted in advance by the formulation. In the method, back-propagation (BP) algorithm was proposed to map the complex relationship between additive components and quality indexes of formulation. The genetic algorithm was employed to optimize the BP neural network weight and threshold. The results showed that the prediction display a satisfied consistence with the test and the error is less than 5%, and also indicated that the combining BP-GA method was an effective tool to predict the performance of aerosol fire extinguishing agent by the formulation designed. © (2014) Trans Tech Publications, Switzerland.

The expansion mechanism of expandable graphite (EG) was studied systematically in this paper. Based on the feature of the structure and the linear expansion of expandable graphite, a simple expansion model was established by the energy balance and mass balance equation. And the model was modified by setting of the boundary conditions. The result showed that a good agreement is confirmed by comparing the test data and model, especially the two inflection points of the growth rate. The study may provide theory support for improving using condition and expand application fields of the expandable graphite. © (2014) Trans Tech Publications, Switzerland.
