A Novel Authentication Scheme Based on Trust-value Updated Model in Adhoc Network

There are many difficulties to carry out node authentication in dynamic and self-organized adhoc network. A Trust-value Updated Model (TUM) in Layered and Grouped adhoc network Structure is adopted in this paper, and based on which, we put forward a novel authentication mechanism of leader agent and member surveillance, which can cut down the data traffic of authentication between nodes, and the calculating complexity is reduced greatly, hence the node authentication efficiency is improved, the realtime communication between the nodes is ensured.
