适合于多频道移动Ad Hoc网络的媒体接入控制协议研究

提出了一种适用于移动Ad Hoc网络的媒体接入控制协议．在该协议中，所有的节点被划分成若干个子网，且每个节点可处于不同的子网．相邻的子网采用不同的频道．在一个子网中，采用令牌来控制各个节点依次进行传输，以便解决传输的碰撞问题．通过限制每个子网中的最大节点数，来保障实时业务的服务质量．同时，文中还提出一种动态令牌传递算法，该算法无需预先建立逻辑的令牌传递环路，而是根据网络的拓扑结构，动态地选择令牌的传递路径．因此，它能很好地适应网络拓扑结构的变化，并简化了令牌的维护过程．

Study of the medium access control protocol for the multiple channels mobile Ad Hoc network

A novel medium access control protocol is presented for the mobile Ad Hoc with multiple channels.In this protocol,all nodes are clustered into several subnets and it is possible for a node to belong to more than one subnet.Different subnets are in different channels.In each subnet,a token is used to control the nodes transmited in turn,which can solve the problem of transmitting collisions.The quality of service(QoS) for real-time traffic is guaranteed by limiting the maximum number of nodes in each subnet.Besides these,the token dynamic transfer algorithm is proposed which can adaptively choose a path to transfer the token,so it has the ability to adapt the dynamic network topology and simplifies the process of token maintenance.
