Abstract

Mobile P2P is an important research field in recent years, due to the defects of mobile environment; network security of mobile P2P becomes a key factor for its application. Therefore, how to establish effective credibility model is an important research content, a master-slave Chord recommended credibility model is presented in the paper. Adopting the different class management, the nodes are divided into the super nodes (index server) and ordinary ones (clients) according to different data structure and functions, which constitutes hybrid credibility model and enhances the velocity and efficiency of credibility value updating and maintenance. Semi-distributed architecture reduces the terminal computational and storage load, which can make the proposed model be applicable to the mobile P2P, meanwhile improve the flexibility and scalability of network.
