Abstract
In a volunteer-based self-organizing network, such as a peer-to-peer
network and a wireless ad-hoc network, trustworthiness of each participant node is crucial to assure information security and resilience of the
whole network. We call this kind of network a “decentralized” network.
In a decentralized network, mutual evaluation of trust among nodes
are considered useful to manage trustworthiness in many studies. As
far as we know, all the preceding related studies discussed trust management upon stable mature networks. However, most decentralized
networks in reality begin with initial states comprised of a small number of nodes, and grow gradually with new-comer nodes joining in.
This paper proposes a new trust management method for a growing decentralized network. The network grows from the initial stage
where we assume all the initial nodes are trustworthy enough. This
paper exhibits that our method extending GossipTrust brings better
performance and better quality of trust evaluation than the original
GossipTrust.
