A Propagation Model of Reputation Query Request
Reputation is a key factor to enhance reliability and performance of transactions in the network. Many works have focused on rating the reputation of the entities through kinds of technologies. The entities send the request messages about reputation to other entities when they need the reputation of the target entities. Considering the nodes population is highly transient in open network, and the number of requests and responses are also various, this paper builds up a model about propagation of reputation query request. It reveals relationship of query request times, connect rate and response rate. It is a valuable reference to set the scope of TTL in Gnutella. Through reducing the number of query requests, it’s significant to efficiently solve the problems about bottleneck of bandwidth and denial of service attacks.
