A service-oriented dynamic trust vector model for ad hoc networks

In service oriented architecture, Quality of Service (QoS) is an important index for an interaction or a cooperation in network. Whereas, considering the particular properties of service, more attention needs to be paid to the transmission environment and the requirement of service. In this paper, we introduce a trust vector to evaluate the network, including secondhand information and propose a fast-decreasing, slow-increasing trust management system, which incarnates a punishment to malicious behaviors. Also, a routing approach based on trust vector to select the most appropriate routing for services is proposed. And a simulation is given in the end, which shows a better performance of trust vector model.
