The Study Of Multi-strategy Trust Evolution Model For Internetware Based On Wright-Fisher

According to the basic characters of Internetware, this paper studies the trust problem ofInternetware in complex and open network environment. Combined with evolutionarycharacteristic of Internetware, according to fuzzy theory, information entropy theory,evolutionary game theory, ecological evolution theory and classic game theory, this paperproposes multi-strategy trust evolution model of Internetware based on Wright-Fisher.Considering of the present shortcomings of existing researches, this paper studies the trustproblem of Internetware from the following aspects:1. To solve the uncertainty problem of trust property values, this paper builds trustmeasure model of Internetware using fuzzy theory and information entropy theory.2. To describe the diversity and fuzziness of trust behaviors in complex networkenvironment and further enhance adaptability of trust evolution model, as well as improveprediction accuracy about trust evolution, this paper puts forward the Wright-Fishermulti-strategy trust evolution model of Internetware based on discriminatory service.3. To avoid free-riding problem, this paper proposes an incentive mechanism based ongame theory to promote entities to select trust strategy and improve the trust of system.In view of above problems, this paper proposes a kind of trust measure model forInternetware based on rough-fuzzy. For solving uncertainty problem of trust property values,this paper brings rough-fuzzy theory into trust measure, and puts information entropy theoryinto the weights calculation of different trust property values. Combined with the complexitycharacteristic of open network, this paper proposes a kind of Wright-Fisher multi-strategytrust evolution model of Internetware based on the discriminatory service theory to simulateand predict trust evolutionary trend of Internetware system. On basis of the model, this paperestablishes corresponding incentive mechanism, so as to improve efficiency of network andmake profit of Internetware achieve optimal.
