摘　　要：本文设计了一种采用动态令牌算法的MANET多址接入协议,解决了隐藏终端和入侵终端问题.利用这种算法,不再需要为令牌的传递预先建立虚拟的令牌逻辑环路,而是根据当前的网络拓扑结构自动地形成令牌的传递路由,使得令牌的传递能够适应网络拓扑结构动态的动态变化.同时,通过周期性地产生令牌并严格地限制每个令牌的生存时间,简化了令牌的维护过程,并为时延敏感的业务提供良好的QoS保障.另外,该协议采用一种互同步技术,具有成本低廉、运行可靠的特点,可完全独立于其它系统(如GPS等),且已应用于实际的MANET网络.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 comolexity.
