Similarity-based hierarchical structured trust and reputation model in peer-to-peer networks

Trust and reputation system has been a key component in P2P networks since all peers are intellectual and autonomous. Previous researches either ignore particular peer's needs or sacrifice efficiency in storage and retrieval to adapt to diversity of peer's preferences. This paper aims to propose a scheme achieving quicker access and more precise calculation of reputation data. This system utilizes peer's self estimation in calculation and provides a hierarchical structure for retrieving information.
