摘　　要：提出了适用于移动AdHoc网络中的一种新的令牌传递算法,即令牌动态传递算法。该算法无需预先建立虚拟的逻辑令牌传递环路,而是根据网络的拓扑结构,动态地形成令牌的传递路径。因此,在移动AdHoc环境下应用时,能够根据网络的拓扑结构的变化,动态地改变令牌的传递路径,具有很好的适应拓扑结构变化的能力。A novel algorithm of token transfer,named as token dynamic transfer algorithm(TDTA) ,is proposed in this paper, which can be adopted as the multiple access control (MAC) protocol in mobile Ad Hoc network. The logic token transfer ring needs not to be established in advance for the TDTA. The path through which the token transfers is dynamically formed according to the network topology. When the network topology is changed, the path of token transfer can automatically adapt to the change. So TDTA make the token transfer has the ability to fit the mobile Ad Hoc network.
