Smart Home brings a new people-oriented home life experience. However, the edge devices in this system are facing severe threats\nsuch as data security and equipment safety. To solve the above problems, this paper proposes an intrusion detection scheme based\non repeated game. We first use the K-Nearest Neighbors (KNN) algorithm to classify edge devices and equip the intrusion\ndetection system to cluster heads. Secondly, we use the regret minimization algorithm to determine the mixed strategy Nash\nequilibrium of the one-order game and then take a severe punishment strategy to domesticate malicious attackers. Thirdly, the\nintrusion detection system can detect malicious attackers by reduction of payoff. Finally, the detailed experimental results show\nthat the proposed scheme can reduce the loss of attacked intrusion detection system and then achieve the purpose of defending\nagainst the attacker....
In this paper, the game theoretical analysis method is presented to provide optimal strategies for anomaly-based intrusion\ndetection systems (A-IDS). A two-stage game model is established to represent the interactions between the attackers and\ndefenders. In the first stage, the players decide to do actions or keep silence, and in the second stage, attack intensity and detection\nthreshold are considered as two important strategic variables for the attackers and defenders, respectively. The existence,\nuniqueness, and explicit computation of the Nash equilibrium are analyzed and obtained by considering six different scenarios,\nfrom which the optimal detection and attack actions are provided. Numerical examples are provided to validate our\ntheoretical results....
Although haze risk management is mainly under government control, willingness of stakeholders is compulsory to determine.\nTherefore, this study constructs a tripartite game model of government, public, and enterprises and determines the haze risk\nevolution model considering the initial willingness of stakeholders. Moreover, numerical simulation analysis was also conducted.\nThe results revealed that stakeholders were affected by the change due to initial willingness to participate in and reach the\nequilibrium at different speeds. It is found that if subsidy coefficient of the government is big, it will reach equilibrium faster. The\nbigger the penalty coefficient is, the better the pollution reduction effect of pollutant discharge enterprises. It is found that, at the\nfinal equilibrium stage, the government will eventually choose to withdraw from supervision, but the speed of withdrawing varies\nwith different regulatory intentions. Study results stress that the government should actively participate in supervision to reduce\nenvironmental pollution....
With technology getting to the next level, many resources cannot only educate\nour children and youth, but also let them know what our religion is all\nabout. The idea is to educate and make our children aware, but in a way that\nmakes them happy and suits the cause. Designing an application, which let\nusers know about various verses and words of Holy Quran in easy way, is\nvery important. This study helps children to relate all those words with real\nlife, reel life and later then will recognize them easily. The illustration in this\nstudy plays a key role to do the research in a right way....
The smoothness of surface shape is one of the key issues to simulate coalescence of underwater bubbles. In this paper, B-spline\nclosed curve is used to realize the visual simulation of multibubble coalescence. The main idea of the proposed algorithm is to\nconstruct a continuous bubble deformation which is guided by the normal direction of each control point and weighted by the\ndistance from the point to the geometry center of the contour. The advantages of this algorithm include the smoothness of the\nbubble contour in the processing of deformation and the randomness of dynamic process and coalescence process. Experiment\nresults show that the simulation algorithm works well and can be used in 3D computer games and animations....
