A novel multiple access control protocol with dynamic token algorithm for MANET is proposed in this paper.The algorithm does not need to establish the virtual token transfer ring in advance.The path through which the token transfers is automatically formed according to the current network topology

which makes the path adapt to the dynamic network topology.To simplify the maintenance process of token and satisfy the QoS requirements of real-time service

the token is periodically established and the lifetime of each token is strictly limited.Furthermore

an interactive synchronization method is presented in this protocol

which make the system operation completely independent on the other system (such as GPS etc.)

as well as has the reliable performance and lower complexity.
