Because the node of vehicular ad-hoc networks has the characteristics of high mobility and encounter temporary, a trust management between the nodes in the routing process becomes more difficult. To solve this problem, this paper proposes a new trusted routing protocol in VANET based on GeoDTN＋Nav by using trust management model of Bayesian and the three opportunistic routing forwarding models, which includes four steps of the routing initialization, the routing discovery, the trusted routing establishment and the routing deletion. The proposed protocol not only improves the security of routing, but also has the lower time complexity. Besides, experimental results and analysis show that the protocol has achieved good performance in the removal ratio of malicious nodes, correct reception ratio of packet and the message payload.

Rumor Spreading Model with Trust Mechanism in Complex Social Networks

引用

Communications in theoretical Physics 2013年第4期59卷 510-516页

作者：王亚奇杨晓元韩益亮王绪安 Department of Electronics Technology Engineering University of the Chinese People's Armed Police Force

In this paper, to study rumor spreading, we propose a novel susceptible-infected-removed （SIR） model by introducing the trust mechanism. We derive mean-field equations that describe the dynamics of the SIR model on homogeneous networks and inhomogeneous networks. Then a steady-state analysis is conducted to investigate the critical threshold and the finaJ size of the rumor spreading. We show that the introduction of trust mechanism reduces the final rumor size and the velocity of rumor spreading, but increases the critical thresholds on both networks. Moreover, the trust mechanism not only greatly reduces the maximum rumor influence, but also postpones the rumor terminal time, which provides us with more time to take measures to control the rumor spreading. The theoretical results are confirmed by sufficient numerical simulations.

Virus spreading in wireless sensor networks with a medium access control mechanism

Chinese Physics B 2013年第4期22卷 70-74页

作者：王亚奇杨晓元 Network and Information Security Key Laboratory of armed police Force Department of Electronics Technology Engineering University of the Chinese People's Armed Police Force

In this paper, an extended version of standard susceptible-infected （SI） model is proposed to consider the influence of a medium access control mechanism on virus spreading in wireless sensor networks. theoretical analysis shows that the medium access control mechanism obviously reduces the density of infected nodes in the networks, which has been ignored in previous studies. It is also found that by increasing the network node density or node communication radius greatly increases the number of infected nodes. The theoretical results are confirmed by numerical simulations.

In order to prevent and control the spread of rumors, the implementation of immunization strategies for ignorant individuals is very necessary, where the immunization usually means letting them learn the truth of *** the facts that there is always a delay time between rumor spreading and implementing immunization, and that the truth of rumors can also be spread out, this paper constructs a novel susceptible-infected-removed(SIR) *** propagation dynamical behaviors of the SIR model on homogeneous networks are investigated by using the meanfield theory and the Monte Carlo method. research shows that the greater the delay time, the worse the immune effect of the immunization strategy. It is also found that the spread of the truth can inhibit to some extent the propagation of rumors, and the trend will become more obvious with the increase of reliability of the truth. Moreover, under the influence of delay time, the existence of nodes' identification force still slightly reduces the propagation degree of rumors.

In real life, people usually have a herd mentality. This paper studies the influence of herd mentality mechanism on the dynamical behaviors of rumor spreading, and proposes a novel susceptible-infected-removed（SIR） model. Based on the mean-field theory, both the critical threshold of the homogeneous networks and the final rumor size are investigated. theoretical analysis and numerical simulation show that the existence of herd mentality mechanism obviously reduces the network critical threshold, but increases the final rumor size. It is also found that when considering the impact of herd mentality mechanism, the propagation velocity of a rumor on the networks increases significantly, which relatively shortens the time that the rumor spreading research a steady state. In addition, we show that the network parameters can still have a greater influence on the propagation characteristics of a rumor.
