无线传感网络节点模糊信任演化模型
EVOLUTIONARY MODEL FOR FUZZY TRUST OF NODES IN WIRELESS SENSOR NETWORKS
摘要
Abstract
In order to solve the problems of trust evaluation fuzziness and dynamic evolution of trust decision for nodes in wireless sensor networks,this article presents a fuzzy theory-based evolutionary model for trust of nodes in WSNs.The model introduces the subjective trust fuzziness of nodes,and effectively improves the accuracy of trust value classification.On the basis of evolutionary process of trust strategy selection of sensor nodes,it deduces the replicator dynamic equation in sensor nodes’trust evolution process and the theorem of evolutionary stable strategy existence under certain conditions,as well as improves the trust management mechanism of WSNs nodes.Simulation explains the robustness of fuzzy trust value calculation model,verifies the theorem conclusion and analyses the influence of incentive mechanism on steady-state.关键词
