基于信任度评估的移动自组织网络路由协议
Routing Protocol for Mobile Ad Hoc Network Based on Trust Degree Evaluation
摘要
Abstract
Specific to reliability and security problems in Mobile Ad Hoc Network( MANET) ,a trust evaluation model based on Dempster-Shafer( D-S) evidence theory is proposed. Direct trust degree is calculated with historical interaction information and indirect trust is obtained from neighbor nodes’ commendations. The direct trust degree and indirect trust are combined according to Dempster combination rule after being amended with weight,to obtain node’ s comprehensive trust finally. On this basis, it optimizes the Multi-point Relaying ( MPR ) technology in Optimized Link State Routing Protocol(OLSR),and proposes an improved routing protocol ( TOLSR). Simulation result shows that the model can discoveries selfish nodes and malicious nodes,thus effectively improves the reliability of MANET,which also proves the validity and rationality of the trust evaluation model.关键词
