Abstract: Mobile Ad hoc network is a special peer-to-peer network that is infrastructure-less, self-organizing and dynamically reconfiguration and mobile. And now people pay more attention to the using of ad hoc network in emergence area such as battlefield and disaster rescue. Despite security targets of wireless network, MANET has not only its special security requirement, but also additional vulnerabilities and features pertinent to this networking paradigm. This paper presents a novel global trust model and gives a distributed implementation method. Mathematic analyses and simulations show that, compared to the current global trust model, the proposed model is more robust on trust security problems.

Key words: ad hoc networks, trust, recommendation, fuzzy set
