Ad-hoc networks have mass of applications; though, a dynamic problem regarding their security aspects must be answered in order to realize these applications. Validating the source and ensuring the integrity of the message traffic become an essential constraint for the operation and management of the network. The authors focus on the security problem of protecting the network connectivity between nodes in ad-hoc network. New nodes start to contribute in the network as guests; they can only become full members with a network signed certificate after their authenticity has been warranted by some other members. In this paper, they introduce routine of multicast Protocol for tired authentication between the multilevel of ad-hoc network.
